Micron Technology earnings preview: AI demand puts margins and guidance in the spotlight

Micron Technology reports its fiscal fourth-quarter results after the US close on 30 September, with the memory-chip maker's latest earnings set to provide an important test of whether the artificial intelligence boom can continue to drive record revenue, margins and cash flow.

Micron has become one of the major beneficiaries of the surge in AI infrastructure spending. Demand for high-bandwidth memory (HBM), which is used alongside advanced AI processors in data centres, has transformed the company's earnings outlook and helped push profitability to levels rarely seen in the memory-chip industry.

The question for investors is whether the momentum can continue into fiscal 2027.

What is expected from Micron's results?

Micron's own guidance for the fiscal fourth quarter calls for revenue of $50bn, plus or minus $1bn, non-GAAP gross margin of around 86% and adjusted earnings per share (EPS) of approximately $31, plus or minus $1.

Those figures would represent another huge year-on-year increase following a record fiscal third quarter.

Q3 revenue jumped to $41.46bn, from $23.86bn in the previous quarter and $9.30bn a year earlier. Non-GAAP EPS reached $25.11, while operating cash flow surged to $25.39bn.

Gross margin was particularly striking, rising to 84.6%, compared with 74.4% in Q2 and just 37.7% a year earlier.

The fourth-quarter guidance therefore implies that Micron expects both revenue and profitability to continue increasing as the AI-related memory shortage persists.

According to LSEG Data & Analytics, analysts expect Q4 revenue to rise to $51.07bn, pre-tax profit to $42.45bn and EPS to $31.61, all over a 100% higher than in Q4 2025.

AI and HBM remain the main growth engines

The biggest driver of Micron's earnings is increasingly its exposure to AI data centres.

High-bandwidth memory is particularly important because AI accelerators require large amounts of very fast memory to process increasingly complex workloads. Micron's HBM4 products have entered high-volume shipments for leading customers, while the company has also been preparing HBM4E for volume production in 2027.

The scale of the opportunity is reflected in Micron's business mix.

Its Cloud Memory Business Unit generated $13.77bn of revenue in Q3, up sharply from $7.75bn in Q2. Core Data Center revenue more than doubled sequentially to $11.52bn.

Investors will therefore be listening closely to management's comments on HBM demand, customer commitments and the pace at which new products are being adopted.

Memory pricing is the key to margins

For Micron, strong demand is only half the story. The other half is pricing.

Memory manufacturers have historically suffered from severe boom-and-bust cycles. When supply exceeds demand, prices can collapse rapidly and margins can disappear. Conversely, periods of constrained supply can produce dramatic increases in profitability.

The current cycle is unusual because AI-related demand is absorbing a growing proportion of advanced memory production.

Micron's forecast of an approximately 86% non-GAAP gross margin for Q4 suggests management currently expects favourable pricing and product mix to persist.

That makes commentary on Dynamic Random-Access Memory (DRAM) and non-volatile memory (NAND) pricing particularly important.

Samsung has also indicated that HBM could consume an increasingly large proportion of industry DRAM capacity. If manufacturers continue allocating capacity towards HBM, supplies of conventional DRAM could remain relatively constrained, potentially supporting pricing.

The risk, however, is that the industry eventually adds too much capacity. Investors will therefore want to know how Micron is balancing capacity expansion against demand visibility.

Fiscal 2027 outlook could overshadow Q4

While the September-quarter numbers will be important, the market reaction could ultimately depend more on what Micron says about fiscal 2027.

Expectations have risen rapidly alongside the company's earnings. That means simply beating its own $50bn revenue guidance may no longer be sufficient to drive the shares higher if management adopts a more cautious outlook.

Investors will want evidence that AI demand is creating a more durable memory upcycle rather than simply producing another short-lived period of supply shortages and elevated prices.

Particular attention is likely to be paid to:

• HBM demand and pricing
• DRAM and NAND average selling prices
• Hyperscaler and data-centre spending
• Capital expenditure plans
• HBM4 and HBM4E production
• Fiscal 2027 revenue and margin expectations

Multi-year customer agreements are also becoming increasingly important because they could give Micron greater visibility over future demand and reduce some of the cyclicality traditionally associated with the memory market.

Capital expenditure will be closely watched

Micron is investing heavily to expand production capacity.

The company spent $7.1bn on capital expenditure in Q3, although this was more than offset by its substantial cash generation. Adjusted free cash flow reached $18.3bn and Micron ended the quarter with $30.2bn of cash, marketable investments and restricted cash.

The investment programme is necessary if Micron is to capture the expected growth in AI-related memory demand.

However, investors will be watching for signs that capital expenditure could eventually create excess capacity. This is particularly important given the memory industry's history of aggressive investment followed by periods of oversupply.

The balance between capacity growth and demand growth could therefore be one of the most important longer-term issues discussed on the earnings call.

Buybacks could become a catalyst

Shareholder returns are another potential area of interest.

Micron currently pays a quarterly dividend of $0.15 per share, but the bigger potential catalyst is the company's ability to resume share repurchases.

Restrictions associated with funding received under the US Chips Act have limited Micron's ability to buy back shares. Those restrictions are expected to expire in December 2026, potentially giving management greater flexibility to return excess cash to shareholders.

With cash generation accelerating sharply, investors may look for an indication of how Micron intends to allocate capital once those restrictions expire.

Micron shares: what matters now?

The extraordinary improvement in Micron's fundamentals has already changed the way investors view the company. It is no longer simply a cyclical memory-chip manufacturer waiting for the next upturn in pricing.

AI infrastructure spending has created a powerful new source of demand, while HBM has become strategically important to the semiconductor supply chain.

But that also means expectations are considerably higher.

A strong fourth-quarter result accompanied by bullish fiscal 2027 guidance could reinforce the view that the current memory cycle has further to run. Conversely, signs that HBM demand is slowing, pricing is approaching a peak or capital expenditure is running ahead of demand could raise concerns about the sustainability of current margins.

Technical analysis of the Micron share price

​The Micron Technology share price – up 269% year-to-date – remains in a strong uptrend with the September peak at $1,108.72 remaining in sight. If bettered on a daily chart closing basis, the June all-time high at $1,255 may be back in sight.

​Micron Technology weekly candlestick chart

​The medium-term uptrend is deemed to remain intact while the 24 August low at $887.61 holds on a daily chart closing basis.

​For now good support lies between the 9 July-to-9 September highs at $1,042.40-to-$1,011.77 and withstands downside pressure.

​Only a bearish reversal and fall through the late August low at $887.61 may push the late July low at $737.88 to the fore.

Key figures to watch on 30 September

​The bottom line: Micron's September results are likely to be less about whether the company can deliver another record quarter and more about how long the AI-driven memory boom can sustain its exceptional growth and margins.

​With the market already expecting extraordinary numbers, fiscal 2027 guidance, HBM demand and the outlook for memory pricing could prove more important than the headline Q4 results themselves. The key question is whether Micron can turn the current AI-driven surge into a durable, less cyclical earnings cycle.
