• Wolfe Research reiterated its Outperform rating on SK Hynix (000660.KS) with a $250 price target, citing strong HBM demand and potential for a 28% share buyback over two years.
  • The bullish call follows SK Hynix's record third-quarter results, with revenue up 328% year-over-year and operating profit surging 632%, beating analyst estimates.
  • The company outlined plans for HBM4 to overtake HBM3E in Q4 and announced approximately 100 trillion won in shareholder returns for 2026, including dividends and buybacks.

Record Quarter Bolsters Bull Case

Wolfe Research's Chris Caso sees substantial upside for SK Hynix, reiterating an Outperform rating and a $250 price target, according to a note to clients. The analyst points to robust demand for high-bandwidth memory (HBM) used in AI infrastructure, potential for HBM pricing gains, and attractive valuation at approximately 4.5 times bull-case earnings. Wolfe also estimates that SK Hynix could generate enough free cash flow to repurchase 28% of its shares over two years, assuming its projected shareholder-return policy.

The bullish stance is underpinned by SK Hynix's latest quarterly results, released on October 28, which showed record revenue and operating profit. Third-quarter revenue reached 104.62 trillion won, up 328% from a year earlier, while operating profit hit 83.33 trillion won, a 632% increase. Both figures surpassed analyst expectations, with the operating profit beating the 76.7 trillion won consensus estimate reported by Reuters (TRI). The company's operating margin stood at roughly 80%.

HBM4 Transition and Capacity Expansion

During the earnings call, management said it expects HBM4 to overtake HBM3E in both shipment volume and revenue in the fourth quarter. To support that transition, SK Hynix plans to bring its M15X facility to maximum capacity by year-end. The company also highlighted signed long-term agreements with 14 major customers covering more than 50% of total production capacity for 2027 and 2028, providing greater demand visibility. Management's broader claim that DRAM and HBM are effectively sold out through 2029 includes customer demand still under negotiation, not all of which is contractually committed.

Capital Returns and Solidigm IPO Shelved

SK Hynix plans approximately 100 trillion won in shareholder returns this year, including at least 30 trillion won in cash dividends and at least 60 trillion won in share repurchases and cancellations. These totals include previously announced commitments. Notably, the latest 20 trillion won repurchase authorization includes about 10 trillion won earmarked for employee compensation, which the company excludes from its shareholder-return total. Additionally, CEO Kwak Noh-Jung said the company has decided to discontinue consideration of an IPO for its storage subsidiary Solidigm, citing current financial-market conditions that would not deliver the intended outcome. The company is also returning most of its realized Kioxia (285A.T) investment gains through special dividends.

Analyst's Hypothetical Buyback and Valuation

Wolfe's estimate of a 28% share repurchase is a hypothetical scenario based on projected free cash flow, not a guaranteed outcome. A September report corroborated Caso's Outperform rating and $250 target (raised from $200) but cited a different hypothetical cash-return figure: sufficient 2026-27 free cash flow to repurchase shares equivalent to 32% of SK Hynix's market capitalization. The exact "4.5 times bull-case earnings" calculation could not be independently verified, and the figures may reflect different model dates or assumptions. It is important to note that cash flow equivalent to a percentage of market capitalization does not automatically translate into that percentage of shares being retired, as the outcome depends on repurchase prices, dividends, investment requirements, and cancellation policies.

Operational and Regulatory Headwinds

While the outlook is robust, risks remain. SK Hynix operates manufacturing facilities in China that use American equipment, and U.S. export controls continue to pose a challenge. Washington granted annual equipment-shipment licenses for 2026 after previous exemption arrangements ended, making continued access more dependent on regulatory approvals. In October, Reuters reported that SK Hynix was seeking additional permission for equipment exports to China in connection with discussions over a possible U.S. factory, though the company subsequently told TechCrunch it was not seeking to expand capacity at its Dalian facility. Regulatory decisions can affect the timing and cost of capacity expansion independently of customer demand.

Market Reaction and Outlook

Investors welcomed the results, with CNBC reporting an approximately 11% share-price jump on October 28. Management expects memory shortages to persist through 2030, citing difficult manufacturing processes and long factory-construction lead times, but that forecast is not guaranteed. Expanding industry capacity, weaker AI spending, or more effective competing products could eventually reduce pricing power. The low "bull-case earnings" multiple in Wolfe's thesis should be read as a conditional valuation argument: it looks compelling if the optimistic earnings scenario materializes and endures. The latest operating results support the direction of Wolfe's thesis, but they do not establish that the $250 target, the exact 4.5-times multiple, or a 28% share retirement will be realized.

Update: This article was updated to clarify that Wolfe's 28% buyback estimate is a hypothetical scenario and that SK Hynix's shareholder return figures include previously announced commitments.
