Micron Q3 Earnings Preview: Gross Margin Expected to Break the 80% Mark? Wall Street Is Unanimously Bullish, Sold-Out HBM Capacity Becomes Greatest Backing

TradingKey - As the June 24 release window for Micron Technology ( MU )'s fiscal third-quarter 2026 earnings report approaches, Wall Street's performance expectations for this memory giant are being pushed to new heights.

The market consensus forecasts that Micron's Q3 EPS will reach $19.72, skyrocketing 932% year-over-year, while revenue is expected to top $34.38 billion, representing a 270% surge year-over-year, slightly higher than the company's previous revenue guidance of $33.5 billion and EPS guidance of $18.90.

The core driver supporting this staggering growth is the explosive demand for high-bandwidth memory (HBM) from AI servers—Micron's HBM capacity for the entire year of 2026 has already been fully booked, with orders stretched to the end of the year.

Q2 Earnings Review

Looking back at Micron's fiscal second-quarter 2026 performance, it already amply demonstrates its strong growth momentum.

Revenue for the quarter reached $23.86 billion, surging 196% year-over-year and growing 75% quarter-over-quarter, which not only exceeded the upper limit of the company's guidance but also beat market expectations by 21%. Adjusted gross margin reached a record 75%, and adjusted EPS was $12.20, soaring 682% year-over-year and beating market expectations by over 33%, marking the company's largest earnings beat in nearly three years.

Both of its core business segments delivered stellar performances, with the Cloud Memory Business Unit (CMBU) seeing revenue grow 47% quarter-over-quarter, and the Core Data Center Business Unit (CDBU) posting a 139% quarter-over-quarter revenue increase.

In terms of cash flow, Micron also delivered a robust performance, with second-quarter operating cash flow reaching $11.9 billion, free cash flow at $6.9 billion, and cash reserves of nearly $14.6 billion at the end of the period, while GAAP net income skyrocketed 770.8% year-over-year to reach $13.79 billion.

Growth in the HBM business

Micron's High Bandwidth Memory (HBM) capacity for the entirety of 2026 and even into early 2027 has been fully booked by customers, a robust demand that underscores the central strategic role of HBM in the AI server market.

Notably, the production ramp-up speed of Micron's next-generation HBM4 has reached twice that of the previous-generation HBM3. This technological breakthrough not only significantly shortens the capacity ramp-up cycle but also demonstrates Micron's robust technical reserves in addressing the explosive growth of AI computing demand.

In the upcoming earnings report, investors should monitor the visibility of its 2027 HBM supply, which directly impacts Micron's ability to meet the long-term demands of the AI server market, as well as the mass production progress of HBM4 and its integration with Nvidia's Vera Rubin architecture.

As the complexity of AI models continues to rise, demand for high-bandwidth, low-latency memory will sustain its growth. As a leader in the global memory market, Micron's technological prowess and capacity footprint will directly influence the pace of development in the global AI industry.

Focus on record-high gross margin guidance

As Micron Technology approaches its fiscal third-quarter 2026 earnings release, the market's focus is locked on a key metric: management's 81% gross margin guidance. Achieving this target would not only break the company's profit records once again, but also serve as a landmark event in the industry's evolution. It would prove that Micron has secured unprecedented pricing power in the memory chip sector; while revenue growth can be driven by increased shipments, a gross margin as high as 81% is a dual testament to product premium capability and cost-control prowess.

Looking back at the fiscal second-quarter earnings released in March, Micron's financial results demonstrated that the memory chip industry is undergoing a profound transformation. Its gross margin soared to 74.4% from 36.8% a year earlier. This breakthrough, exceedingly rare in a traditionally cyclical industry, completely shattered the market's perception of memory manufacturers' earnings ceilings.

In terms of industry trends, the memory chip sector is transitioning from a 'cyclical industry' to a 'growth industry.' AI has not only generated massive demand for memory but has also reshaped the technical standards and value propositions of memory products. The traditional cyclical patterns of wild price swings driven by supply-demand mismatches are being disrupted by AI-fueled long-term demand growth.

Micron CEO Sanjay Mehrotra has repeatedly emphasized during earnings calls that both AI servers and traditional servers are currently facing DRAM and NAND supply shortages. This supply crunch is expected to persist beyond 2026, providing solid support for product pricing in both the short and medium term.

Micron's earnings guidance is in focus.

For the upcoming third-quarter earnings report, the market's focus is not just on the financial results themselves, but more importantly on Micron's forward guidance and its outlook on industry trends.

Nova Capital pointed out that two core variables in the current memory chip industry are rewriting traditional cyclical logic: first, the strategic scarcity of memory chips, and second, the operational strategy of leading manufacturers to actively control production.

Memory chip manufacturers now prefer to extend the cycle through long-term supply agreements and securing commitments from strategic customers, ensuring stable production volumes and pricing over the coming quarters.

Research from Nova Capital shows that even though manufacturers began capacity expansion last year or even earlier, new market supply will remain highly limited between 2026 and 2027.

Micron’s two giant fabs in Idaho and New York will not achieve volume shipments until mid-2027 and 2028–2030, respectively. Its newly built NAND flash facility in Singapore is also not expected to begin production until the second half of 2028. Similarly, SK Hynix’s M15X line and Samsung’s P5 line will not ease supply tightness until late 2027 to 2028, reflecting an industry-wide capacity shortage.

Nova Capital emphasized that a reversal in the industry's upward cycle would require oversupply, but based on current conditions, this is highly unlikely to occur over the next 12 to 18 months. Consequently, upstream manufacturers are expected to maintain strong pricing power over the long term.

Wall Street is unanimously bullish

Recently, major Wall Street investment banks have collectively raised their price targets for Micron Technology, demonstrating strong optimism regarding the memory chip giant's growth prospects in the AI era.

UBS analyst ( UBS) Timothy Arcuri's latest report is particularly noteworthy, as he hiked Micron's price target from $535 to $1,625, a massive 204% increase, setting the highest price target currently given to Micron on Wall Street.

UBS analysts believe that Micron has signed long-term volume and pricing agreements (LTAs) with the vast majority of its core customers. These agreements not only secure revenue for multiple years to come but also mark a fundamental transformation of the company's business model from a traditional cyclical stock to a growth tech stock.

In addition to UBS, institutions such as Deutsche Bank and TD Cowen have also raised Micron's price target, lifting it to $1,500, while Morgan Stanley and Raymond James set their price targets at $1,050 and $1,100, respectively.

Independent Wall Street research firm Aletheia Capital has also joined the bullish camp, not only raising its price target from $650 to $1,600, but also maintaining its Buy rating.

Aletheia Capital provided a highly aggressive forecast in its research report, predicting that the value share of AI memory components in AI hardware systems will surpass 70% by 2027, completely disrupting the market's traditional perception of the status of memory chips.

The core logic behind this forecast lies in the continuous surge in HBM and server DRAM prices, as well as a structural leap in the share of memory components within the AI hardware bill of materials (BOM). If this prediction materializes, Micron is poised to become one of the primary beneficiaries of this AI hardware cycle.
