SK hynix Inc. (NASDAQ:SKHY) has established itself as the market leader in AI memory, but its valuation still looks surprisingly modest compared with rival Micron Technology, Inc. (NASDAQ:MU).
That’s the disconnect investors may want to consider, as the AI boom turns high-bandwidth memory (HBM) into one of the semiconductor industry‘s most valuable assets.
According to Benzinga Pro, SK Hynix trades at a trailing price-to-earnings ratio of 9.7x, compared with 21.3x for Micron. The gap is equally notable on an EV-to-EBITDA basis, where SK Hynix trades at 8.2x versus Micron’s 15.3x.
SK Hynix Leads the AI Memory Race, but the Valuation Says Otherwise
As Nvidia Corp’s (NASDAQ:NVDA) leading supplier of high-bandwidth memory for its latest AI accelerators, SK Hynix continues to expand production capacity to meet surging demand. Management has repeatedly highlighted robust AI-driven demand, and this week announced a record 40 trillion won ($28.6 billion) share buyback alongside an enhanced shareholder return policy, citing confidence in its long-term cash generation.
Despite those advantages, the stock continues to trade at a substantially lower trailing multiple than Micron.
Forward valuations tell a different story. SK Hynix trades at roughly 6.0x forward earnings, almost identical to Micron’s 6.1x.
That suggests investors expect strong earnings growth from both companies over the coming year, even though the market currently assigns a much richer trailing multiple to Micron.
The Valuation Gap May Reflect More Than AI Fundamentals
The disparity does not necessarily mean one stock is mispriced.
Micron and SK Hynix operate in the same industry but are listed in different markets, face different investor bases and are subject to different geopolitical and governance considerations. Those factors can influence valuation multiples independently of operating performance.
Our inference is that the market may also be assigning a persistent “Korea discount” to SK Hynix—a phenomenon long discussed by investors in South Korean equities due to governance structures, capital allocation practices, and geopolitical risk.
SK Hynix itself appears intent on narrowing that perception through more aggressive shareholder returns, including its newly announced buyback and commitment to return more than 50% of cumulative free cash flow generated between 2025 and 2027.
Technical Momentum Is Turning Positive for SK Hynix Stock
The valuation story is unfolding alongside improving price action.
Chart created using Benzinga Pro
According to Benzinga Pro, SK Hynix shares have reclaimed both their 8-day and 20-day moving averages, while the shorter-term average has crossed above the longer-term average. Momentum indicators have also strengthened, with the Moving Average Convergence Divergence (MACD) indicator turning positive and the Relative Strength Index (RSI) hovering around 52, suggesting the recent rally is gaining momentum without yet entering overbought territory.
Technical indicators do not predict future performance, but they suggest investors have begun rewarding the company’s improving fundamentals following its latest capital allocation announcement.
What Investors Should Watch Next
The more important comparison may not be today’s valuation multiple but whether SK Hynix can sustain its leadership in the AI memory market.
If demand for HBM remains robust, capacity expansions stay on track, and the company continues to pair strong earnings growth with shareholder-friendly capital allocation, investors may begin to question why the industry’s AI memory leader still trades at such a meaningful discount to one of its closest peers.
Whether that gap narrows—or persists—could become one of the more closely watched valuation stories in semiconductors over the coming year.
