Micron Earnings Beat: Gross Margin Exceeds Nvidia, Memory Shortage May Extend to 2028

Against a backdrop of rising global semiconductor industry activity, Micron Technology's recent quarterly earnings injected strong confidence into the market. Not only did revenue and profit both beat Wall Street expectations, but its gross margin historically surpassed chip giant Nvidia, and management's forecast of an extended memory shortage shocked investors—supply-demand tightness could persist until 2028. These signals not only highlight Micron's leadership in memory but also profoundly impact the investment logic of the US semiconductor sector.

Earnings Highlights: Record Gross Margin

Micron's latest quarterly report showed revenue growth of over 80% year-over-year, with an even more significant net profit increase. Most striking was its gross margin of 62%, not only well above market expectations but also surpassing Nvidia's margin for the first time. This breakthrough was driven by strong pricing power in DRAM and NAND Flash core businesses, as well as cost optimization from advanced processes. Analysts note that driven by demand for AI servers, data centers, and high-end storage, Micron's high-value product shipment share increased significantly, effectively lifting overall profitability.

Memory Shortage Continues: Supply Bottlenecks Hard to Resolve

More alarming for the industry, Micron management clearly stated during the earnings call that the current memory market supply-demand imbalance will not ease in the short term and is expected to extend to 2028. This forecast far exceeds the previous consensus of a recovery by 2025-2026. Three structural factors combine: first, the exponential growth in demand for high-bandwidth memory (HBM) from AI model training and inference consumes significant advanced process capacity; second, global semiconductor manufacturing equipment delivery cycles remain at 18-24 months, with slow ramp-up of new fabs; third, limited supply elasticity for mature memory products due to return on investment constraints.

Notably, Micron is not alone in issuing warnings. Samsung and SK Hynix have also indicated that capex in 2024-2025 will remain focused on HBM, with significantly slower expansion of conventional DRAM and NAND. This means that from smartphones and PCs to automotive electronics, almost all memory-dependent end industries will face sustained cost pressure.

Profound Impact on US Semiconductor Sector

Micron's earnings beat and long-cycle shortage forecast are reshaping valuation logic for the semiconductor industry. On one hand, sustained memory price increases will directly boost cash flow for major players like Micron and Samsung, enabling more investment in next-generation R&D, forming a virtuous cycle. On the other hand, GPU makers like Nvidia and AMD face the embarrassment of being overshadowed in margins—Nvidia had enjoyed gross margins above 65% thanks to AI chip dominance, but Micron's rapid approach suggests the focus of AI infrastructure investment is shifting from compute chips to memory architecture.

However, a profit model overly reliant on price increases also carries risks. If the macro economy slides into recession, downstream demand could suddenly shrink, leading to inventory buildup and price crashes. Micron has experienced boom-bust cycles multiple times. The forecast extending to 2028 is based on current AI wave assumptions. Breakthroughs in technology paths or alternatives (e.g., compute-in-memory, new non-volatile memory) could disrupt the current landscape.

Conclusion: Opportunities and Challenges Coexist

Overall, Micron's latest earnings not only solidify its status as a core beneficiary of the memory cycle reversal but also reveal a trend in the global semiconductor industry evolving from 'compute-centric' to 'memory-centric'. For US stock investors, Micron and its supply chain companies (e.g., equipment maker Applied Materials, materials supplier Dow Chemical) could become long-term allocation targets for years. However, caution is needed: if the ultra-long shortage expectation is disproved, the industry will face significant valuation pressure. Whether Micron's gross margin can sustain its lead over Nvidia, and whether the memory shortage can truly last until 2028, are key variables determining core trends for semiconductors over the next five years.
