Micron Technology (NASDAQ:MU) Stock

Shares of memory provider Micron Technology have surged more than 310% over the past year. AI-driven demand for the company’s memory solutions and higher pricing amid a supply crunch have boosted investor sentiment.

After delivering a 196% rise in its Q2 FY26 revenue, the company expects continued momentum in its business. Micron expects to deliver top-line growth of $33.5 billion plus or minus $750 million in Q3 FY26, reflecting a tremendous jump from $9.3 billion in the prior-year quarter.

Despite fears that Alphabet-owned Google’s GOOGL -0.54% ▼ new compression method, TurboQuant, could lower the need for memory, most analysts remain bullish on Micron stock due to continued demand and pricing strength.

Is Micron a Good Stock to Buy?

Following his meetings with over 15 tech supply chain companies in Asia, RBC Capital analyst Srini Pajjuri reiterated a Buy rating on Micron stock. The 5-star analyst noted that AI and data center component demand remains strong, with no indications of a deceleration. Pajjuri expects tight supply conditions to persist through 2026, driving prices higher in many cases. Furthermore, he noted that limited cleanroom space remains the major hurdle for memory and 3nm chip supply, with EUV (Extreme Ultraviolet) lithography machines emerging as the next potential challenge.

Meanwhile, Pajjuri sees a continued rise in DRAM (dynamic random access memory) pricing, given persistent cleanroom constraints that are expected to last until the second half of 2027. Additionally, Pajjuri noted that data centers are expected to account for more than 70% of the DRAM market in 2026, so any drop in demand from PCs and smartphones should not have a significant impact on pricing.

With 26 Buys and three Holds, Wall Street has a Strong Buy consensus rating on Micron stock. At $533.53, the average MU stock price target indicates about 46% upside potential.

Seagate Technology (NASDAQ:STX) Stock

Seagate Technology offers mass-capacity data storage. The company is seeing solid growth in revenue and earnings, driven by demand for data storage to support AI training and inferencing. In Q2 FY26, the company delivered a 210 basis-point sequential expansion in adjusted gross margin to 42.2% and a 290 basis-point sequential jump in adjusted operating margin to 31.9%, reinforcing strong data center demand trends.

In the Q2 conference call, CEO William Mosley said that Seagate’s nearline capacity through calendar year 2026 is fully allocated and the company expects to begin accepting orders for the first half of calendar year 2027 in the months ahead. STX stock has risen 56% year-to-date and jumped 402% over the past year.

Is Seagate a Good Stock to Buy?

Recently, JPMorgan analyst Samik Chatterjee initiated coverage of Seagate Technology stock with a Buy rating and a price target of $525. Despite the spike in STX stock since early 2025, the analyst assigned a Buy rating, citing the potential for significant upside to consensus estimates, with the hard disk drive (HDD) industry well-positioned to benefit from hyperscaler spending plans and higher pricing.

The 5-star analyst expects Seagate to deliver a 25% revenue CAGR (compound annual growth rate) and more than 50% operating earnings CAGR over the medium-term.

Overall, Wall Street has a Strong Buy consensus rating on Seagate Technology stock based on 13 Buys and four Holds. The average STX stock price target of $465.81 indicates 8.5% upside potential.

Marvell Technology (NASDAQ:MRVL) Stock

Marvell Technology stock has risen 69% over the past year, driven by the demand for custom AI chips and networking solutions in data centers. Last month, the company reported impressive results for the fourth quarter of Fiscal 2026 and issued robust guidance for Fiscal 2027.

Notably, the company expects its year-over-year revenue growth to accelerate in each quarter of Fiscal 2027, driven by continued strength in its data center business. Meanwhile, Marvell is strengthening its product portfolio with strategic acquisitions. It recently completed acquisitions of Celestial AI and XConn Technologies and expects them to add $250 million in aggregate revenue in Fiscal 2028.

Recently, Nvidia NVDA +0.93% ▲ announced a $2 billion investment in Marvell as part of a new partnership, which will enable customers to develop next-generation infrastructure on NVDA architectures with greater choice and flexibility.

Is MRVL Stock a Buy, Sell, or Hold?

Following the news of the Nvidia deal, RBC Capital analyst Srini Pajjuri reiterated a Buy rating on Marvell Technology stock with a price target of $115. The 5-star analyst expects Nvidia’s investment to further bolster Marvell’s solid presence in scale-out and scale-up optical connectivity markets, enhance its XPU franchise, and expand SAM (serviceable addressable market) through NVLink Fusion and Telecom/Edge markets.

Though surprised by Nvidia’s equity investment, Pajjuri considers it a “validation” of Marvell’s connectivity leadership and custom silicon capabilities. While the analyst left his estimates intact, he sees upside to Fiscal 2028 from the Nvidia collaboration.

Overall, Wall Street has a Strong Buy consensus rating on Marvell Technology stock based on 23 Buys and five Holds. The average MRVL stock price target of $120.48 indicates 12.5% upside potential.

Conclusion

The three AI infrastructure stocks discussed here are well-positioned to gain from continued demand. Currently, Wall Street is bullish on the growth prospects of Micron, Seagate, and Marvell. Of the three AI infrastructure stocks, analysts see higher upside potential in Micron stock, driven by strong memory demand and elevated pricing amid supply constraints.
