Micron Technology's latest quarterly revenue and profit both beat market expectations, but more noteworthy than the results themselves is management's view on long-term supply and demand: for the first time, the company made clear that HBM capacity supply in 2027 and 2028 will be tighter than in 2026, while simultaneously expanding HBM production at four major manufacturing sites in Taiwan, China: Taoyuan, Taichung, Tongluo, and Tainan.

According to a report by Taiwan, China media outlet DigiTimes on October 2, Dong Huilu, Vice President of Micron's Asia DRAM Front-End Manufacturing and Chairman of Micron Taiwan, confirmed that AI is driving strong memory demand, and the company is advancing expansion at all four sites in parallel. Extending the tight-supply judgment explicitly to 2027 and 2028 is the biggest incremental information from this earnings report.

This statement upgrades HBM's supply constraint from a short-term narrative to a medium-term structural judgment. Its direct implication is that even if the entire industry is expanding capacity, HBM's strong pricing cycle may last longer than previously expected, and the support period for memory makers' profit center will also be extended.

Analysts believe that Micron proactively flagging tighter supply while beating earnings not only endorses its own expansion logic, but also means downstream AI chip makers will still face a tight bargaining environment in 2027 and 2028.

Meanwhile, Morgan Stanley released a latest research note pointing out that Micron Technology's latest quarterly results were basically in line with prior expectations. Although the pace of sequential improvement slowed somewhat, the business's strong resilience remains prominent.

More critically, the company extended its qualitative supply-demand guidance to 2028 and expects memory supply-demand conditions in 2027 and 2028 to be tighter than this year. The bank believes this signal may not be fully priced in by investors in the short term, but it is consistent with its view that the strength of AI demand will reshape the memory industry. Morgan Stanley maintained its overweight rating on Micron with a price target of $1,200.

Tight expectations extended to 2028 for the first time

Micron's revenue and profit for the fourth quarter of fiscal 2026 both exceeded expectations. Compared with the results, the company's statement on the long-term supply-demand landscape has more pricing implications: capacity supply in 2027 and 2028 will be tighter than in 2026.

This judgment is consistent with previous management comments. Micron CEO Sanjay Mehrotra previously said that AI-driven memory demand is extending tight supply and demand beyond 2027, and data center customers' current purchase intentions are about 150% of the company's committable supply, meaning demand exceeds supply by about 50%. Long construction cycles for new wafer fabs and constraints on skilled workers and energy infrastructure make it difficult for supply to keep up quickly.

Four major Taiwan sites expand in parallel

Micron disclosed simultaneous HBM capacity expansion at four major manufacturing sites in Taiwan, China: Taoyuan, Taichung, Tongluo, and Tainan. Dong Huilu confirmed that AI is the core driver of this round of expansion. The company did not disclose the specific expansion scale and production timeline for each site.

Taiwan, China is an important pillar of Micron's HBM capacity expansion. Previous industry information showed that Micron plans to increase monthly HBM capacity to about 100,000 wafers by the end of the year, nearly doubling from last year, with HBM packaging operations mainly advancing at its Tongluo plant in Taiwan, China. The simultaneous moves at four sites show that Micron is turning Taiwan into a core base for HBM capacity expansion.

In the HBM market, Micron has long ranked third. According to data from market research firm Counterpoint Research, in global HBM market share in the second quarter of this year, SK Hynix led with 50%, Samsung Electronics accounted for 32%, and Micron accounted for 18%.

Micron is accelerating its catch-up. Its HBM4 has begun mass production supply for Nvidia's Vera Rubin platform, and it plans to mass produce HBM4E next year. At the same time, it is locking in long-term demand through five-year strategic customer agreements. By the end of June, it had signed with 16 customers, and its capital expenditure plan for fiscal 2026 exceeds $25 billion. If supply is indeed tighter in 2027 and 2028, customers that lock in capacity early will receive priority supply, and Micron's ranking in market share is expected to move further up.
