Introduction

Late June is typically an off-season for US earnings reports, with most major companies having already disclosed results weeks earlier. However, one report due this week is enough to capture the attention of global investors: US memory chip giant Micron Technology will release its FY2026 Q3 earnings after the US market close on Wednesday. For the market, this is not just an ordinary quarterly scorecard but an important window to observe the health of the AI industry chain, the position of the semiconductor cycle, and changes in the overall earnings structure of US stocks.

Over the past year, Micron's stock performance has been exceptionally strong. It has risen about 260% year-to-date and over 8-fold in the past year, officially joining the trillion-dollar market cap club last month. This rapid rise is not simply due to valuation expansion but is driven by fundamental improvements from the changing supply-demand landscape in the memory market and the explosive growth in AI demand.

1. Wall Street Raises Expectations Ahead of Earnings

On the eve of the earnings report, several major Wall Street banks have raised their target prices for Micron, reflecting institutional optimism about its profit outlook. Wedbush raised its target from $550 to $1,300, Stifel from $550 to $1,500, and Deutsche Bank from $1,000 to $1,500. Such dense and significant upward revisions are rare among large tech stocks, indicating market confidence in Micron's earnings momentum over the coming quarters.

This optimism is not unfounded. As Micron scales up and its margins improve significantly, its earnings performance is having a growing impact on the S&P 500. FactSet data shows that Nvidia and Micron are expected to be the largest contributors to S&P 500 Q2 profit growth. Joe Butters, senior earnings analyst at FactSet, noted that without Nvidia and Micron, the expected earnings growth rate for the S&P 500 in Q2 would drop from 22% to 14.9%. This means Micron is no longer just a cyclical representative in the semiconductor space but a key pillar for overall US stock profit growth.

2. AI Demand Drives Memory Chip into High Prosperity Cycle

The core logic behind Micron's earnings explosion is the reevaluation of storage demand driven by artificial intelligence. The previous semiconductor cycle focused more on computing chips, but the market is now recognizing the critical role of storage in AI infrastructure. Whether for training large models or deploying inference applications, data throughput, bandwidth, and latency are crucial, making HBM (High Bandwidth Memory) a core component of the AI era.

Morningstar analyst William Kerwin noted that Micron's growth over the past 12 months has been "stunning," essentially driven by tight memory chip supply causing prices to soar, leading to substantial profit growth, almost directly translating into profits. Unlike traditional cycles, this price increase is not only due to demand recovery but also to structural upgrades in demand: AI servers, data centers, and high-performance computing require far more advanced storage products than before.

Meanwhile, Micron is accelerating its shift toward the HBM business. Compared with traditional DRAM, HBM products have higher technical barriers, stronger profitability, and greater customer stickiness. For Micron, this means its revenue growth no longer relies solely on a single price cycle but is gradually embedding itself into the core of the AI supply chain with greater certainty.

3. Profit Growth May Peak, but Absolute Levels Are Still Rising

FactSet survey shows the market expects Micron's adjusted EPS for the May quarter to reach $20.57, a year-over-year increase of nearly 1,000%. This figure is itself highly striking, far above the $1.91 in Q3 FY2025. Many analysts believe Micron will likely significantly beat expectations this quarter because memory chip prices remain high and industry supply expansion is limited.

However, from a growth rate perspective, this quarter may approach the peak of the current cycle. The market expects Micron's EPS growth rate for the August quarter to be about 725%, still impressive but lower than the current quarter's year-over-year increase. This does not mean Micron's growth momentum is weakening; rather, it reflects base effects, and future earnings will be more characterized by "high absolute growth" rather than "extreme high growth."

Looking further ahead, the market expects Micron's EPS for the next May quarter to reach $31.70, with a year-over-year growth rate of 54%, but in terms of profit scale, it is still a leapfrog improvement. In other words, Micron is transitioning from a "burst recovery" phase to a "high-profit plateau," with profitability expected to stabilize at a higher level.

4. Reshaping Industry Landscape, Micron's Strategic Value Rises

From an industry standpoint, Micron has become a backbone of the Philadelphia Semiconductor Index. According to Dow Jones market data, Micron's net profit for calendar years 2026 and 2027 is expected to be second only to Nvidia in the semiconductor sector. Even more striking, Micron's net profit for calendar year 2027 is projected to reach $136.7 billion, nearly on par with Apple and well above Amazon and Meta Platforms. Although this forecast still involves cyclical and supply-demand variables, it shows that capital markets are beginning to view Micron as a "high-quality profit asset," not just a traditional cyclical stock.

Stifel analyst Brian Chin believes Micron is in the true sweet spot of its cyclical expansion, with unprecedented momentum. This judgment is based on the resonance of industry supply constraints and AI demand expansion: on one hand, capacity expansion takes time, and supply release is limited in the short term; on the other hand, AI server construction is accelerating, driving sustained demand for HBM and high-end DRAM. Jack Gold, chief analyst at J.Gold Associates, also noted that memory chip prices are unlikely to decline significantly until capacity catches up with demand, a process that will last at least 12 to 18 months.

Conclusion

Overall, Micron's upcoming earnings report is both a periodic test of its high-speed growth over the past year and a key sample to observe whether the AI industry chain still has strong resilience. The company is not facing the question of "whether it will grow" but rather "how long growth can last and how high profits can climb."

In the short term, market expectations have been significantly raised, and earnings volatility may increase; but in the medium to long term, Micron's strategic position in HBM, high-end DRAM, and AI infrastructure determines its strong earnings extensibility. If this earnings report continues to validate the three logics of firm memory prices, strong demand, and margin expansion, Micron will not only further consolidate its semiconductor leadership but also become a key engine driving S&P 500 profit growth.

For investors, Micron's value is no longer just a trading opportunity from "cycle reversal" but a microcosm of the repricing of the storage industry in the AI era.
