Micron Technology (MU) shares rose about 3% to 4% in pre-market trading on Wednesday, following record third-quarter results from memory industry peer SK Hynix. MU closed Tuesday's session up 2.77%, and the stock has more than tripled in value this year.

The linkage is structural. Micron, SK Hynix, and Samsung Electronics together supply the overwhelming majority of the world's DRAM and high-bandwidth memory — the memory types going into AI servers — so a quarter from any one of the three doubles as a reading on pricing and demand conditions across the entire memory industry.

Record Quarter for SK Hynix

SK Hynix reported revenue of 104.62 trillion won, the first time the company has surpassed the 100 trillion won mark in a single quarter. Operating profit came in at 83.33 trillion won, up 632% from a year earlier, which works out to an operating margin of about 80%.

It was the sixth straight quarter of record revenue and operating profit for the South Korean chipmaker. SK Hynix's American depositary receipts rose 7.7% in pre-market trading, while its Seoul-listed shares closed up almost 11%.

What SK Hynix Told the Market

The line that drew the most attention came in the company's outlook. SK Hynix said demand is expected to outpace supply through 2030, and that structural imbalances between memory supply and demand should persist for that long. The company added that its DRAM and high-bandwidth memory (HBM) supply is effectively sold out for the next three years, with long-term agreements already covering a large portion of its 2027 and 2028 output.

That outlook carries weight because Wall Street has been pricing in a possible drop in memory prices after 2028 — the point at which SK Hynix and Samsung Electronics are set to open seven new memory fabrication and packaging plants, according to research firm Trendforce. SK Hynix's own order book, for now, tells a different story. And because Micron sells DRAM and HBM into the same data-center demand pool, how long that imbalance holds is as pertinent to its results as to SK Hynix's.

HBM4, the next generation of high-bandwidth memory used in AI servers, entered full-scale mass production in the third quarter. SK Hynix expects the newer memory to pass HBM3E in both shipment volume and revenue share in the fourth quarter, and it guided for mid-20% DRAM bit shipment growth in the period.

Chief Financial Officer Kim Woo-hyun said the company plans to return about 100 trillion won to shareholders through fiscal 2026. The plan includes at least 30 trillion won in cash dividends and at least 60 trillion won in buybacks and share cancellations, making it the biggest such commitment in the company's history.

Micron's Own Tailwinds

Micron has catalysts of its own. Bank of America's semiconductor analyst maintained a Buy rating and a $1,550 price target on the stock after a series of executive meetings, saying he came away "incrementally more positive on memory." Hana Securities, meanwhile, kept Micron on its list of 10 global AI investment picks.

Both calls came ahead of Wednesday's Federal Reserve decision, where interest rates are widely expected to hold steady. Investors are watching the Fed's statement for any hawkish language.

Buybacks are another point of interest. Under the terms of its 2024 U.S. Chips Act funding, Micron can begin major repurchases on Dec. 9. UBS analyst Timothy Arcuri has said the company could start with roughly $20 billion a quarter, a pace he expects to climb to about $50 billion a quarter toward the end of fiscal 2027, which ends in September of next year.

Despite this year's run, Micron still trades at a comparatively cheap valuation, a reflection of lingering concerns about the cyclical memory market — a business long defined by shortage-driven booms and glut-driven busts. Elon Musk's prediction that humanoid robots could need more memory than any other application also made the rounds, and at least one analyst described it as a potential volume opportunity for Micron. Form 4 filings for Oct. 27 show insider activity, and several institutions reported larger stakes in recent 13F filings.

The Wider Market

Broader markets were mixed. The S&P 500 closed Tuesday at 7,722.60, up 0.6%, while the Nasdaq rose 1.18%.

For Micron, the next catalyst arrives on Dec. 9, when the company can begin its stock buybacks. Before then, SK Hynix's fourth-quarter report — in which it expects HBM4 to overtake HBM3E in shipment volume and revenue share — will provide another industry-level data point on AI memory demand.
