SK Hynix: Memory Shortage to Last Until 2030, Buy SKHY and MU

SK Hynix, the South Korean memory chip giant, announced that it expects the global memory chip shortage to persist through 2030, citing difficulties in leading-edge manufacturing and long construction times for new plants. This forecast comes on the heels of record third-quarter results, with revenue surpassing 100 trillion won for the first time, up 328% year over year to about 104.6 trillion won, and operating profit soaring 632% to around 83.3 trillion won, an 80% operating margin.

The company has secured long-term agreements with 14 major customers, including top cloud providers, covering over 50% of its production capacity for 2027 and 2028. It also plans about 100 trillion won in shareholder returns for 2026 and ended the quarter with net cash of 98.7 trillion won. Despite these strong fundamentals, SK Hynix's stock trades at only 4 to 5 times expected 2027 earnings.

Micron Technology, based in Idaho, is similarly optimistic. Management expects memory supply to remain tight through 2028 and cannot yet see when supply and demand will balance. Micron has signed 26 strategic customer agreements—multiyear take-or-pay deals—that cover more than 35% of its revenue through 2030, with some extending into 2031. Customers have backed these commitments with $32 billion in cash deposits. Micron also reported record operating margins of about 81% in its fiscal Q4 2026, with revenue rising to $54.2 billion from $11.3 billion a year earlier.

However, both companies are seeing decelerating sequential growth. SK Hynix's revenue growth slowed from 51% to 32% quarter over quarter, and operating profit growth from 61% to 38%. Micron's guidance for fiscal Q1 2027 implies sequential growth of around 13%, down from 31% in the prior quarter. Despite this, both stocks remain cheap, with Micron trading at about 5.5 times expected fiscal 2027 earnings.

The memory industry is historically cyclical, and the 2018 shortage ended abruptly, leading to a sharp profit decline at SK Hynix and a 54% drop in Micron's stock. New supply is also coming: Micron's second Idaho fab is due to begin wafer output in late 2028, and its first New York fab in 2030. Yet, at current valuations, investors seem to be pricing in a fast profit decline, while the companies' contracts suggest otherwise.

If SK Hynix's forecast proves accurate, the memory chip industry could experience an unprecedented period of sustained demand exceeding supply, fundamentally altering the boom-bust cycle that has historically plagued memory stocks. This would mean prolonged pricing power and elevated margins for manufacturers, potentially justifying higher valuations than the current 4-6 times earnings.

The long-term contracts signed by both SK Hynix and Micron provide a level of revenue visibility that is rare in the semiconductor industry. SK Hynix's deals cover over 50% of its 2027-2028 capacity, while Micron's take-or-pay agreements cover more than 35% of revenue through 2030, with $32 billion in customer deposits. These commitments suggest that major customers—likely cloud providers and AI companies—are willing to lock in supply well into the future, indicating confidence in persistent demand.

However, the market is skeptical. Both stocks trade at low multiples, implying investors expect profits to peak soon and then decline sharply, as in previous cycles. This skepticism is rooted in history: the 2018 shortage ended quickly, and memory stocks lost more than half their value even as earnings were still strong. The concern is that new capacity coming online in 2028-2030 could tip the market into oversupply, especially if demand growth slows.

For investors, the key question is whether this cycle is different. The rise of AI and cloud computing may have structurally increased memory demand, and the difficulty of building new fabs could keep supply constrained for longer. If so, the current low valuations offer a compelling opportunity. But if history repeats, the downside could be significant. The decelerating growth rates already hint at a potential peak, making this a high-risk, high-reward scenario.

Ultimately, the news matters because it challenges the market's conventional wisdom. SK Hynix and Micron are essentially betting that their long-term contracts and the capital intensity of the industry will prevent a repeat of past busts. Investors who believe them can buy at bargain prices, but they must be prepared for volatility along the way.
