Can Micron's AI Memory Focus Help It Outpace SK Hynix and Sandisk?

Micron Technology, Inc. MU is sharpening its focus on artificial intelligence (AI) memory as demand for high-bandwidth memory (HBM), DRAM and data-center storage accelerates. The strategy is producing strong financial results, but Micron still faces tough competition from SK Hynix Inc. SKHY in HBM and Sandisk Corporation SNDK in NAND.

Micron's third-quarter fiscal 2026 revenues surged 346% year over year to $41.46 billion, while non-GAAP earnings reached $25.11 per share compared with $1.91 a year earlier. Data-center demand was particularly strong, with revenues exceeding $25 billion during the quarter.

HBM is central to Micron's AI strategy. The company has already generated more than $1 billion in HBM4 revenues, while its 12-high HBM4 ramp is progressing twice as fast as its HBM3E 12-high ramp. HBM4 is already shipping in high volumes to a lead customer, with additional customers receiving qualification samples.

However, SK Hynix remains a formidable HBM competitor, with a reported 58% HBM market share, according to a Counterpoint report. Micron competes with Sandisk mainly in the NAND memory market. Sandisk holds a 13% share in the global NAND memory market, according to a Counterpoint report. Micron has a 21% share in the global HBM market and 13% in the global NAND memory market.

Micron's advantage is its broad exposure to both memory and storage, along with rapidly improving HBM4 execution. If it maintains this pace while expanding advanced packaging capacity, AI could help Micron narrow SK Hynix's HBM lead and outperform Sandisk's storage-focused growth. The Zacks Consensus Estimate for fiscal 2026 and 2027 revenues indicates a year-over-year increase of 247% and 91%, respectively.

How Do SK Hynix and SanDisk Fare Against Micron?

SK Hynix is Micron’s strongest competitor in HBM, where AI accelerator demand is driving rapid growth. Its early HBM leadership gives it an important advantage. The rapid buildout of AI data centers has triggered a global shortage of memory products, driving demand across industries ranging from cloud computing to consumer electronics.

As a key supplier of AI memory chips to NVIDIA, SK Hynix is well-positioned to capitalize on the AI boom. Leveraging its relationship with NVIDIA, the company is expanding its manufacturing capacity to keep pace with rising demand fueled by the ongoing global AI investment cycle. In the recently reported results for the second quarter of 2026, SK Hynix’s revenues surged 257% year over year, while net income jumped 1,242%.

Sandisk is a more direct competitor in NAND and enterprise SSDs, rather than HBM. In the fourth quarter of fiscal 2026, Sandisk’s revenues soared 372% year over year to $8.97 billion, while non-GAAP net income jumped to $6.16 billion from $42 million in the year-ago quarter. Sandisk is benefiting from AI-led demand that is lifting enterprise SSD adoption and supporting pricing across NAND end markets. Its data-center revenues jumped 437% year over year to $5.15 billion in fiscal 2026.

SanDisk also has signed long-term supply agreements, adding some demand visibility. During its fourth-quarter fiscal 2026 earnings call, SanDisk revealed that it holds eight long-term contracts with six customers worth $93.9 billion. The average length of contracts is four years. SanDisk expects half of its bit production to be covered by these deals in fiscal 2027 and two-thirds in fiscal 2028.
