SK Hynix Q3 Profit Surges 632% on AI Memory Boom, Driving $45B Shareholder Pledge

Key points

• SK Hynix's third-quarter operating profit jumped 632% year-over-year to 83.33 trillion won, setting a record alongside revenue of 104.61 trillion won.
• The company announced a new shareholder return plan totaling 60 trillion won, following a previous 40 trillion won program, with specific allocations for dividends and buybacks.
• SK Hynix's US-listed shares rose 8% premarket, while Korea-listed shares gained 11%, triggering a rally in memory peers Micron (+4.8%) and SanDisk (+5.6%).
• Net profit of 39.77 trillion won missed the analyst consensus of 59.67 trillion won, despite record operating margins.
• SK Hynix expects HBM4 to surpass HBM3E in shipments and revenue in the fourth quarter, with long-term agreements covering over 50% of 2027-2028 production capacity.

Background

This follows a trend of record profits in the memory sector, including Samsung's recent Q3 results. Earlier coverage noted that while SK Hynix's earnings were strong, market sentiment had been cautious due to fears of a peak in AI spending. The current results aim to reverse a 60% decline from June highs.

How outlets are covering it

Outlets diverged on the shareholder return figures. Yahoo Finance cited a $45 billion pledge based on AFP reporting, while CNBC detailed a 100 trillion won total return plan (including 30 trillion won in dividends and 60 trillion won in buybacks). Bloomberg noted that strong earnings had not previously lifted memory stocks, contrasting with the recent rally. Analysts remain split on sustainability, with some warning of a 2018-style demand pullback, while others see supply constraints lasting through 2030.

Why it matters

The results validate the ongoing memory shortage, particularly for HBM used in AI chips. The shareholder returns address investor concerns over valuations, while the strong performance supports the thesis that AI infrastructure demand remains robust despite high interest rates.

What to watch

Investors will watch SanDisk's October 29 earnings and Micron's upcoming reports for confirmation of the memory cycle. The Federal Reserve's interest rate decision later in the week will also influence tech sector valuations.
