KB Securities has issued a revaluation case for Samsung Electronics, tying the call to high-bandwidth memory (HBM) price strength and a richer expected return profile, according to a Chosunbiz dispatch. The note flags Samsung's memory franchise as the principal lever for any consolidated earnings revision through 2025.

The Korean brokerage's bullish note leans on three operational observations from the HBM market:

• Contract prices for HBM3E have firmed across recent quarters as AI accelerator demand continues to outstrip qualified supply.
• Samsung's qualification footprint across next-generation HBM products has widened with multiple accelerator platforms.
• The combined revenue and margin mix shift is set to lift the memory division's return on invested capital above the trailing twelve-month baseline.

What is driving the HBM price surge?

HBM is the vertically stacked DRAM category that feeds the high-bandwidth memory controllers of Nvidia's H100, H200, and B100 data-center accelerators, alongside custom AI silicon from AMD's MI300 family and hyperscalers including Google and Amazon.

Each accelerator die bonds to multiple HBM stacks through advanced 2.5D or 3D packaging, with HBM3E 8-Hi 24 GB modules the current volume reference point in the merchant market. HBM3E 12-Hi products are now sampling with key customers.

The segment runs as a three-supplier oligopoly: Samsung Electronics, SK Hynix, and Micron Technology. SK Hynix entered the HBM3 generation first and captured the bulk of Nvidia's H100 allocation through 2023.

Samsung worked to qualify HBM3 and HBM3E products with multiple customers across that period, with Korean and Taiwanese trade checks pointing to qualification wins extending through 2024.

Why does the call matter for Samsung's earnings?

The revaluation arithmetic hinges on the spread between HBM ASPs and commodity DDR5 contract prices. HBM modules carry unit prices several multiples higher than standard server DRAM.

KB Securities argues that as accelerator shipments scale into 2025 and 2026, Samsung's memory division compounds that mix effect, lifting consolidated operating margins above the trailing baseline. The earnings revisions flow through to revised price targets and target multiples on the Korean bourse.

What are the residual execution risks?

Three variables remain open:

• Qualification timelines with Nvidia's H200 and B100 platforms must hold, particularly for Samsung's HBM3E 12-Hi product.
• Yield ramp on HBM3E 12-Hi and 16-Hi products must track demand without capacity bottlenecks at the packaging supply chain.
• Competition from SK Hynix's HBM4 development and Micron's HBM3E ramp sets a ceiling on the price umbrella the segment commands.

How does the call fit the broader re-rating debate?

The call lands against a broader re-rating debate across the Korean memory complex. SK Hynix trades at a market-implied premium reflecting its HBM3 incumbency on Nvidia platforms.

Samsung's discount has historically reflected qualification delays, foundry exposure, and conglomerate discount factors. A sustained HBM upcycle that re-prices Samsung's memory franchise would compress that gap.

KB Securities' revaluation note adds to a growing chorus of broker upgrades across the AI memory supply chain. HBM contract pricing visibility through 2025 is now the central debate among Korean and Taiwanese memory analysts, with allocation decisions for 2026 accelerator volumes the next data point to watch.
