SK Hynix Bets on Rack-Scale Memory as CXMT Closes the Gap Before October 28 Earnings

SK Hynix used this year's OCP Global Summit to roll out a stack of AI-focused memory and infrastructure designs, including the memory-centric rack-scale MARS system, High Bandwidth Flash and a second-generation CXL-3.2 product carrying 256 gigabytes of capacity. The platforms, unveiled on Friday, target the bandwidth-hungry server workloads that underpin large-scale artificial intelligence, and they land at a moment when the memory maker's share price is being pulled in two directions at once.

The equity closed Friday at 1,272,000.00 KRW, up 0.8 percent. That modest advance came on the heels of a brutal Thursday, when SK Hynix and Samsung Electronics each shed more than 9 percent, according to Bloomberg, as investors fretted over the Federal Reserve's rate path and the financing burden attached to AI buildouts. By the following session the stock had given back 1.4 percent to 1,254,000.00 KRW, leaving a year-to-date gain of 93 percent — a figure that sits alongside a 96 percent advance reported on a different measurement basis.

A Chinese Challenger With a Denser Cell

Behind much of the recent nervousness is ChangXin Memory Technologies. CXMT president Cao Kanyu has flagged development progress on a denser 4F² DRAM cell design, with server DDR5 modules built on the architecture slated to reach the market by the end of the year. Reuters linked that disclosure, together with broad caution on AI spending, to mounting concerns about tougher competition in memory chips. SK Hynix is countering with concepts that wire memory more directly and efficiently into data-center structures.

The company is also navigating a tight regulatory corridor. At its Dalian fab in China, SK Hynix is seeking US authorizations to install additional American equipment in Module B. Executives told Reuters the work is being carried out in coordination with Washington and does not amount to an expansion of existing production capacity at the site.

Meritz Sticks With Buy, Sees 80.1 Trillion Won Operating Profit

Analysts remain constructive despite the turbulence. On October 12, Meritz Securities kept its Buy rating and lifted its price target to 3.2 million won, projecting operating profit of 80.1 trillion won for the third quarter of 2026. Hard numbers on how the company actually performed arrive shortly: SK Hynix has scheduled its Q3 2026 results for October 28, 2026, with an investor call set for 9:00 a.m. Seoul time. The disclosure was filed with the US Securities and Exchange Commission, and the figures will show how far industry pressure has seeped into earnings.
