Why Micron stock hit a new ATH ahead of earnings

Shares of Micron Technology climbed to an all-time high of $458.21, pushing the company’s market capitalisation to roughly $510 billion, as investors continued to bet on sustained demand for artificial intelligence infrastructure.

The rally marks a sharp 346.88% gain over the past year, reflecting a broader re-rating of memory chip makers amid the ongoing AI boom.

The stock’s move comes just ahead of the company’s quarterly results, scheduled for release after markets close on Wednesday.

The latest rally follows a brief pullback in semiconductor stocks last week, when broader markets declined after US strikes on Iran heightened geopolitical tensions.

Memory stocks have since rebounded, supported by strong underlying demand trends and improving pricing dynamics.

Strong growth expected in upcoming results

Wall Street is anticipating a sharp acceleration in Micron’s financial performance, driven by rising memory prices and robust demand from data center and AI applications.

Analysts expect revenue to rise about 138% year over year to approximately $19 billion.

Adjusted earnings are projected to increase 455% to $8.56 per share, with expectations for third-quarter sales growth of around 140%.

The anticipated surge underscores how quickly the memory cycle has turned, with pricing power returning after a prolonged downturn in DRAM and NAND markets.

AI demand drives memory cycle upswing

The rebound in Micron shares aligns with broader strength across the semiconductor sector, particularly among companies tied to AI infrastructure.

A rapid expansion in data centres and AI servers is driving demand for high-performance memory, including DRAM and high-bandwidth memory (HBM), tightening supply conditions and pushing prices higher.

This dynamic has lifted margins for producers while simultaneously increasing cost pressures for consumer electronics manufacturers.

Industry executives also expect supply constraints to persist.

Chey Tae-won, chairman of SK Group, said the global chip wafer shortage could continue until 2030.

HBM4 rollout strengthens Nvidia ties

Earlier this month, Micron began volume shipments of its latest high-bandwidth memory product, designed for next-generation AI systems.

The company is supplying HBM4 36GB 12H memory for Nvidia’s Vera Rubin platform.

The new memory delivers pin speeds exceeding 11 Gb/s and bandwidth of more than 2.8 TB/s — roughly 2.3 times higher than its previous HBM3E generation — while also improving power efficiency by over 20%.

The rollout positions Micron to capture a larger share of AI-driven memory demand, particularly as hyperscalers ramp up spending on next-generation computing infrastructure.

To support rising demand, Micron is expanding its manufacturing footprint.

The company announced plans to build a new facility at its Tongluo site in Taiwan, aimed at increasing production of advanced DRAM chips.

The expansion reflects the industry’s push to secure supply amid growing demand from AI workloads.

Analyst optimism builds

Brokerage firms have turned increasingly bullish on Micron’s outlook.

TD Cowen raised its price target on the stock to $500, citing expectations for stronger-than-consensus earnings.

The firm projects earnings per share of $10.40 for the February quarter, above the consensus estimate of $8.82.

The positive sentiment has been mirrored across the broader memory ecosystem.

Shares of companies such as SanDisk, Seagate, and Western Digital have also posted significant gains this past year, reflecting improved industry fundamentals.
