Micron Technology (NASDAQ: MU) shares climbed on Wednesday after SK hynix reported record third-quarter earnings and said its dynamic random-access memory (DRAM) and high-bandwidth memory (HBM) output was effectively sold out through 2029. The announcement strengthened the outlook for a memory market where artificial intelligence infrastructure spending is driving demand faster than suppliers can expand production.
Micron rose 4.12% to $967 in premarket trading, according to TipRanks at 09:41 UTC on October 28. The move extended during the US session, with Investing.com later recording shares at $980.33, up 5.55% from Tuesday’s $928.76 close. SanDisk (NASDAQ: SNDK) also advanced in premarket trading, gaining 4.4% to $1,362.24.
The latest advance puts Micron approximately 11.7% above its October 23 closing price of $877.55 and 8.5% above its October 26 close of $903.70. The distinction matters because the $877.55 reference price preceded the October 26 session, when Micron had already advanced nearly 3%.
The immediate catalyst was SK hynix’s earnings announcement in Seoul, which provided fresh evidence that demand for AI memory remains strong. For Micron investors, the central question is whether prolonged supply constraints will sustain selling prices and profitability, or whether additional production capacity and changes in customer spending will eventually weaken the current pricing environment.
SK Hynix Earnings Reinforce the Memory Supply Squeeze
SK hynix reported third-quarter revenue of 104.62 trillion won, exceeding analyst expectations of approximately 98.34 trillion won. Operating profit reached 83.33 trillion won, an increase of approximately 632% year over year. The company reported an operating margin of about 80%, reflecting the strength of demand and pricing for its memory products.
According to SK hynix’s earnings briefing, the combination of existing long-term supply agreements and customer demand under detailed negotiation means its DRAM and HBM volumes are effectively sold out through 2029. The company said long-term agreements already cover more than half of its production capacity for 2027 and 2028.
The distinction between contracted volumes and broader demand is important. SK hynix’s statement does not mean every unit of global memory production has been sold, nor does it establish that all future sales prices are fixed. Rather, it indicates that the company has secured substantial forward demand while continuing to negotiate additional business with customers.
SK hynix also expects the supply-demand imbalance to persist through 2030, according to reporting on its earnings briefing. That outlook suggests the shortage may extend beyond a temporary inventory cycle, although the duration and severity of the imbalance will depend on capacity expansion, customer purchasing decisions and the pace of AI infrastructure investment.
The wider market reaction reflected the strength of the results. The Kospi gained 6.63% on Wednesday, while Samsung Electronics rose 9.01%, according to Korea JoongAng Daily. The gains indicate that investors were reassessing the outlook for the broader semiconductor sector, rather than responding exclusively to Micron-specific developments.
Why Memory Pricing Matters More Than the Headline Rally
For Micron, the most important implication is the potential persistence of elevated average selling prices. Memory manufacturers face substantial capital expenditure requirements, and the profitability of new production depends on the prices they can secure for the chips they manufacture. When demand exceeds available supply, manufacturers can gain greater negotiating leverage with customers, particularly when those customers need reliable access to memory for AI servers.
HBM is particularly important because it is designed to deliver the high memory bandwidth required by advanced AI accelerators. Conventional DRAM also remains essential for server infrastructure, while NAND flash serves a different role in storage products. SK hynix’s comments therefore provide evidence of tight conditions across important memory categories, but the effect on each supplier will depend on its product mix and competitive position.
Micron’s own disclosures have already highlighted the importance of long-term customer commitments and pricing arrangements. FinanceFeeds previously examined the company’s record quarterly results and its outlook for a prolonged memory shortage in Micron’s $54 Billion Quarter and the Shortage Extending Toward 2028. SK hynix’s latest announcement provides an additional industry data point supporting the argument that supply constraints could remain significant beyond the current reporting period.
However, a shortage does not guarantee that prices will rise indefinitely. Manufacturers can increase output, customers can adjust their purchasing schedules, and improvements in chip efficiency can change the amount of memory required for a given computing workload. If new capacity arrives faster than expected or AI infrastructure investment slows, the balance between supply and demand could change.
Competition also remains relevant. FinanceFeeds previously covered concerns about Chinese memory producer CXMT’s plans to advance its DRAM technology in Its Analysis of Micron Stock and the Risks Posed by Expanding Chinese Memory Production. Those concerns do not negate the current supply shortage, but they illustrate why investors must assess both near-term pricing power and the longer-term potential for additional competitors to increase supply.
Micron Stock Gains as Analysts Reassess the Outlook
The latest rally follows a difficult period for semiconductor stocks, when concerns about the sustainability of AI spending and the possibility of a future memory glut weighed on valuations. SK hynix’s results offered a counterpoint to those concerns by showing that current demand is translating into record revenue and operating profit.
TipRanks reported an average analyst price target of $1,621.67 for Micron, based on its analyst consensus aggregate. That figure represents the combined average of individual analyst estimates, not a single bank’s forecast. It should not be interpreted as a guaranteed future price or as evidence that the stock is undervalued without considering the assumptions behind those estimates.
The scale of the difference between the consensus target and Micron’s market price makes the underlying earnings assumptions particularly important. Investors need to determine whether the current pricing environment can support earnings expectations over multiple years, rather than extrapolating one strong quarter or a short-term share-price rally.
Micron’s next results and management commentary will be important for assessing how the company is converting tight industry supply into financial performance. Investors should monitor average selling prices, DRAM and NAND demand, HBM production and customer commitments, capital expenditure, manufacturing yields and the timing of new capacity. Developments in long-term supply agreements may also reveal how much future demand is supported by firm commitments rather than less certain forecasts.
The company’s labour negotiations in Taiwan remain a separate operational consideration. As discussed in FinanceFeeds’ October 26 Micron Stock Analysis Ahead of the Taoyuan Talks and SK Hynix Results, the labour dispute was one of the issues facing investors during the week. The latest industry rally does not resolve that issue, although the immediate share-price response indicates that memory-market developments have become a major focus.
For now, SK hynix has supplied concrete evidence that demand for important memory products remains exceptionally strong and that substantial future capacity is already committed or under negotiation. Micron’s gains reflect the potential benefit of those conditions, but the durability of its pricing power will depend on how supply expands, how customers manage AI spending and whether the company can sustain its own earnings performance as the market develops.
