Micron Technology will release its earnings report after the U.S. stock market closes on Wednesday, with market attention having shifted from the results themselves to management's commentary on the AI capital expenditure outlook from hyperscale cloud customers for next year. This commentary will directly determine whether the stock's 40% rally from its July low can be sustained.

Against the backdrop of persistently robust AI infrastructure demand, Micron Technology (NASDAQ: MU) shares have rebounded more than 40% from their July 29 low, adding approximately $370 billion in market capitalization. Daniel Morgan, senior portfolio manager at Synovus Trust, stated that if management explicitly indicates on the earnings call that they "do not expect hyperscale customers to significantly cut capital expenditure budgets next year and anticipate spending will continue," it would serve as a strong catalyst for the stock.

However, despite recent strong fundamentals, Micron Technology (NASDAQ: MU) shares still trade at approximately 7 times forward earnings, well below the roughly 10 times average of the past two years and significantly lagging the S&P 500's 19 times. Market expectations for a sharp slowdown in growth for fiscal years 2027 and 2028, along with the inherent cyclical risks of the memory industry, continue to weigh on valuation.

Earnings Likely to Be Revised Upward, but by a Narrower Margin

Analysts broadly expect Micron Technology (NASDAQ: MU) to post record-high results for the quarter, but the room for upward revisions has narrowed compared to previous quarters.

According to analyst average estimates compiled by Bloomberg, Micron Technology (NASDAQ: MU) is expected to report net income of $36 billion for its fiscal fourth quarter ending in late August, with revenue of approximately $51.5 billion, representing year-over-year growth of over 1000% and 350%, respectively. Gross margin is projected at 86%, a substantial increase from 46% in the fourth quarter of fiscal year 2025.

Morgan Stanley analysts led by Joseph Moore forecast revenue of $50.024 billion for the quarter, up 20.7% quarter-over-quarter and 342.1% year-over-year, slightly below the market consensus. Their gross margin estimate is 86.4%, above the consensus of 85.3%; their earnings per share forecast is $31.20, slightly below the consensus of $31.49.

In a research note dated September 28, Morgan Stanley indicated that earnings for the quarter are expected to be revised upward, but by a smaller magnitude than in previous quarters. The team noted that current DRAM and NAND market demand is strong with rising prices, but some long-term agreements have price caps, and the quarter spans 14 weeks, which could introduce some technical headwinds.

Next Quarter Outlook: Pricing Momentum Continues, Revenue Could Beat Expectations

For the next fiscal quarter ending in late November, Morgan Stanley forecasts revenue of $57.560 billion, up 15.1% quarter-over-quarter and 321.9% year-over-year, above the consensus of $56.644 billion. DRAM prices are expected to rise 12% quarter-over-quarter, while NAND prices are expected to increase 10%. Gross margin is projected at 88.1%, above the consensus of 85.3%; earnings per share is forecast at $35.57, also above the consensus of $35.07.

Morgan Stanley believes that upward pricing momentum in the DRAM market has become a market consensus, and the NAND market is also gradually forming consensus after TrendForce significantly raised its forecasts. The team estimates that entering the fourth calendar quarter, the starting point for memory prices has already risen 15% to 20% from the previous quarter, with some categories seeing even larger increases.

Regarding demand structure, Morgan Stanley noted that despite some uncertainty in the consumer market, supply has continued to shift toward the enterprise segment, and its channel research indicates that memory purchased by enterprises is being deployed immediately, with limited inventory buildup risk.

Core Debate: Cycle Durability, Not the Height of the Boom

The core debate surrounding Micron Technology (NASDAQ: MU) has shifted from "how good can the boom get" to "how long can the good times last," a transition with profound implications for the stock's repricing.

According to Bloomberg data, Micron Technology's revenue growth is expected to slow dramatically from 247% in fiscal year 2026 to 96% in fiscal year 2027, and further narrow to 12% in fiscal year 2028. This sharp decline in the growth trajectory is the core rationale behind the current valuation discount at 7 times forward earnings.

Shaon Baqui, senior equity analyst at Janus Henderson, stated that if the memory industry can sustain gross margins above 80% and maintain consistent cash flow, it could ultimately drive a repricing of the stock to a higher price-to-earnings multiple.

Morgan Stanley, meanwhile, listed three major investor concerns about the durability of this upcycle: first, the risk of AI server de-specking; second, China's memory supply expansion; and third, capex-driven overall supply increases. In response, the team addressed each concern, stating that AI compute deployment has low price sensitivity for memory demand, China's supply expansion is unlikely to surpass Western manufacturers in the current environment, and its industry research indicates that supply-demand conditions will be even tighter in 2027 and 2028 than currently. Morgan Stanley maintains its overweight rating on Micron Technology (NASDAQ: MU) with a $1,200 price target.

Stock Rebound Sustainability: Valuation Discount Racing Against Catalysts

Micron Technology (NASDAQ: MU) shares have rebounded more than 40% from their July low, with a year-to-date gain of 273%, making it the fourth-best performer on the S&P 500. However, the stock still trades approximately 12% below its June 25 all-time high, and the path to valuation recovery remains incomplete.

Recently, semiconductor sector sentiment has experienced significant volatility. The Philadelphia Semiconductor Index plunged nearly 6% in a single day on September 14, triggered by Anthropic CEO Dario Amodei's call to slow frontier AI model development to strengthen safety safeguards. Subsequently, the popularity of Meta's Muse AI assistant reignited market confidence in consumer AI adoption, driving the semiconductor index to rebound more than 13%.

Additionally, Morgan Stanley noted that Micron Technology's (NASDAQ: MU) share buyback progress also warrants attention. Due to restrictions related to the CHIPS Act, Micron Technology's cash returns have been constrained during this cycle, and buyback capacity is expected to expand after December, though the team advises investors to maintain cautious expectations.

Overall, management's specific commentary on hyperscale customers' 2027 AI capital expenditure during this earnings call will be the key variable determining whether Micron Technology (NASDAQ: MU) shares can break through their previous high and complete a valuation repricing.
