The semiconductor sector is experiencing a historic surge, driven by explosive AI hardware demand. Samsung Electronics recently reported record quarterly revenue of 57 trillion KRW, while SK Hynix is solidifying its leadership in the High Bandwidth Memory (HBM) market. This analysis delves into the financial metrics and market dynamics that suggest these stocks may still be undervalued, despite significant recent gains. We will examine the key indicators and strategic shifts that are defining the current AI hardware supercycle.
Financial Performance and Market Dominance
Samsung Electronics has posted an operating profit margin of 40%, with projections reaching up to 50% in the coming years. Based on projected 2025 earnings of 290 trillion KRW, the current Price-to-Earnings (PER) ratio stands at a mere 4.6x. This is significantly lower than the industry average, suggesting the stock is undervalued relative to its earnings power.
SK Hynix's HBM Leadership
SK Hynix is capitalizing on its first-mover advantage in the HBM market. The company's operating profit margin is an extraordinary 70%, a figure rarely seen even in the pharmaceutical industry. For every 100,000 KRW in sales, the company retains 70,000 KRW in operating profit. With a projected net profit margin of nearly 60%, its PER is estimated at just 3.8x, indicating substantial upside potential.
The Shift to Long-Term Contracts
The semiconductor industry is transitioning from a cyclical model to a stable growth model. Major suppliers like Samsung and SK Hynix are now securing 3-to-5 year supply contracts with upfront payments, a significant shift from previous quarterly or annual agreements. This provides unprecedented revenue visibility and reduces the risk of inventory gluts, fundamentally changing how investors should value these companies.

Valuation Deep Dive and Future Projections
A closer look at the valuation metrics reveals why analysts are setting aggressive target prices. Samsung's projected net profit for 2026 is around 300 trillion KRW. If the stock were to rise 5x from its current level, its PER would still be a reasonable 25x. Similarly, SK Hynix's stock could potentially rise 15x and still not be considered expensive by traditional metrics, given its extraordinary profit margins and dominant market position.
Comparison Table: Samsung vs. SK Hynix Valuation
| Company | Projected Operating Margin (2025) | Projected Net Margin (2025) | Current PER (2025E) | Target Price (KRW) |
|---|---|---|---|---|
| Samsung Electronics | 40-50% | ~40% | 4.6x | 400,000 |
| SK Hynix | ~70% | ~60% | 3.8x | 2,000,000 |
This data suggests that while the stocks have already appreciated significantly, the fundamental earnings power supports further growth. The market is beginning to price in the stability brought by long-term contracts and the sustained demand from AI infrastructure spending.

Conclusion: The AI Hardware Supercycle is Just Beginning
The combination of record earnings, low valuations, and a structural shift towards stable, long-term contracts makes a compelling case for continued investment in Samsung Electronics and SK Hynix. The market is rewarding companies that are essential to the AI hardware buildout. While some volatility is expected, the underlying fundamentals suggest that the current upward trend may persist, making these stocks a core holding for any AI-focused portfolio. Investors should monitor quarterly earnings and global AI spending reports for further confirmation.
