New York, Jan 20, 2026, 16:10 EST — After-hours
- Micron shares closed up 0.9% after a volatile session that briefly pushed the stock above $381
- The chipmaker plans to spend $1.8 billion to buy Powerchip’s P5 fab site in Taiwan, aiming to ramp up DRAM output by 2027
- TD Cowen lifted its price target on Micron to $450, citing deepening memory shortages.
Micron Technology’s shares closed Tuesday up 0.9% at $366.00. The stock swung between a low of $350.22 and a high of $381.04 as investors digested news of a Taiwan expansion deal and fresh analyst upgrades. About 44.9 million shares changed hands during the session.
This shift matters because memory chips, especially those used alongside AI processors in data centers, remain one of the clearest examples of tight supply in the market. When supply is constrained, price fluctuations hit earnings in this semiconductor segment almost immediately.
Capacity updates are grabbing investor focus for a reason. In Micron’s case, the question isn’t whether demand exists—it’s which player can supply enough chips fast enough without driving prices down.
Micron has inked a letter of intent to buy Powerchip Semiconductor Manufacturing’s P5 fab in Tongluo, Taiwan, shelling out $1.8 billion in cash. This acquisition adds around 300,000 square feet of cleanroom space, critical for chip making. The company plans to ramp up DRAM wafer production starting in the second half of 2027 and aims to seal the deal by Q2 2026, pending regulatory sign-off. TrendForce projects this initial phase could account for more than 10% of Micron’s global capacity by the end of 2026. 1
TD Cowen boosted its price target for Micron to $450 from $300 on Tuesday, holding firm on a buy rating. The firm pointed to worsening memory shortages as the key driver. Their analysis forecasts stronger DRAM and NAND prices in the latter half of 2026, which could lift Micron’s earnings potential that year. 2
Stifel’s Brian Chin bumped his price target to $360 from $300 and maintained a buy rating after the Taiwan deal. He called the memory market “favorably tight” and remains “upbeat” on conditions through Micron’s fiscal 2026. 3
DRAM acts as the main working memory in servers and PCs, while NAND flash drives storage devices such as solid-state drives. These markets can shift sharply when supply loosens, making Wall Street particularly attentive to contract talks and “long-term agreements.”
The Taiwan plant won’t solve any supply issues right away, and the timeline remains uncertain. Regulatory approval is still outstanding, raising fresh doubts. According to Investing.com, Aletheia Capital downgraded Micron from buy to hold. The move reflects concerns about HBM3E—the newest high-bandwidth memory technology—and questions over the stock’s valuation relative to its historical price-to-book levels.
Upcoming catalysts are pretty routine. Traders will watch for finalized deal documents and any new details on the Taiwan transaction. Early signs that supply contracts are settling at higher prices into the second half of 2026 will also be in focus.
Keep an eye on macro factors. The U.S. personal consumption expenditures (PCE) price index, a key inflation gauge watched by the Federal Reserve, is set to drop on Jan. 22. 4
