Samsung's Chip Arm Posts Record ₩53.7 Trillion Q1 Profit as HBM4 Ramps for Nvidia

Lead. Samsung Electronics (005930.KS), Korea's largest chipmaker by revenue, reported on April 30 that its Device Solutions semiconductor division generated an operating profit of ₩53.7 trillion ($36.2 billion) in the first quarter of 2026, the largest quarterly chip profit in the company's history. Group-wide operating profit climbed roughly eight-fold year-on-year to ₩57.23 trillion ($38.55 billion) on revenue of ₩133.87 trillion (about $90 billion), per The Korea Times. Management attributed the surge to AI-driven demand for high-bandwidth memory (HBM) and the start of volume HBM4 shipments to Nvidia.

What Happened

In its Q1 2026 earnings release, Samsung disclosed that the Device Solutions division — which houses Memory, Foundry and System LSI — booked ₩81.7 trillion in revenue and ₩53.7 trillion in operating profit, with semiconductor revenue rising 86% quarter-on-quarter, according to a summary of the press release published by TechBuzz. Group net profit reached ₩47.22 trillion ($31.8 billion), more than five times the ₩8.22 trillion booked a year earlier, The Korea Herald reported.

On the same day, Samsung's board declared a Q1 cash dividend of ₩361 ($0.24) per share on both common and preferred stock, for a total payout of ₩2.4533 trillion ($1.65 billion), according to Yonhap News Agency, Korea's national wire service.

On the earnings conference call, executives told analysts that Q1 HBM revenue rose more than three-fold year-on-year, that 7th-generation HBM (HBM4E) samples will ship to major customers from the second quarter, and that the company's leading-edge foundry lines are running at maximum utilization, according to ChosunBiz transcripts. Samsung also said HBM4 — which uses its 6th-generation 10-nanometer-class ("1c") DRAM process — will account for more than half of total HBM revenue starting in Q3 2026.

Why It Matters

This is the first concrete signal that Samsung has converted its long-criticized HBM gap with SK hynix into a profit engine of its own. For three years the consensus among Korean equity analysts has been that Samsung was a generation behind on HBM and would only grudgingly close the gap. A ₩53.7 trillion quarterly chip profit, paired with volume HBM4 shipments into Nvidia's Vera Rubin platform, challenges that consensus and marks an inflection point in the AI-memory cycle: Samsung is now shipping its highest-margin memory product at scale, not sampling it.

The second structural signal is Samsung's own commentary that commodity DRAM is, for the moment, more profitable per bit than HBM — a notable reversal of the 2024–2025 narrative. Management said it will nonetheless preserve a "balanced" production mix because over-rotating into commodity DRAM would, in its words, disrupt AI infrastructure customers (per ChosunBiz). That comment frames how Samsung intends to manage the supercycle through 2026.

Business Impact

The profit step-up is concentrated in semiconductors: Device Solutions accounted for roughly 94% of group operating profit in the quarter on the figures disclosed (₩53.7 trillion of ₩57.23 trillion). The remaining ₩3.5 trillion came from the mobile, display and consumer-electronics units combined, implying continued softness outside chips.

Foundry economics are also shifting. Samsung's foundry chief told the call that leading-edge node utilization is "at peak," driven in part by HBM4 base-die orders, and that 2-nanometer mobile chip mass production will begin in the second half of 2026; the 1.4-nanometer roadmap remains "on schedule," per the company's press release as summarized by TechBuzz.

The ₩2.4533 trillion quarterly dividend keeps Samsung on the same ₩9.8 trillion annualized run-rate it has paid since the 2021–2023 shareholder-return program, a level that has remained unchanged through the 2023 memory downturn and the present AI boom (per Yonhap).

Industry & Historical Context

For context, Samsung's group operating profit a year earlier was ₩6.68 trillion, meaning today's print represents roughly an eight-fold year-on-year jump (per The Korea Times). The ₩53.7 trillion quarterly semiconductor figure exceeds the ₩44.57 trillion in total semiconductor operating profit Samsung booked across all of fiscal 2018, the prior memory peak.

The HBM4 ramp also reorders the industry pecking order. SK hynix, the incumbent HBM leader, was the sole HBM3E supplier to Nvidia for much of 2024–2025; Samsung's announcement that it has begun "industry-first" volume HBM4 shipments for Nvidia's Vera Rubin platform — first confirmed in Samsung's February 12 newsroom post — places the two Korean memory makers in direct, simultaneous competition at the most advanced node for the first time this cycle.

What to Watch

• HBM4E sampling: Samsung says first HBM4E samples ship to major customers in Q2 2026. Customer qualification timing will determine 2027 share.
• HBM4 mix: Management guided that HBM4 will exceed 50% of HBM revenue from Q3 2026 (per ChosunBiz). Watch whether that timeline holds as SK hynix ramps its own HBM4.
• Foundry utilization: Samsung said leading-edge foundry is "at peak." The H2 2026 start of 2-nm mobile mass production is the next concrete checkpoint.
• DRAM mix discipline: Samsung explicitly chose not to over-allocate wafers to higher-margin commodity DRAM. If commodity DRAM prices keep rising, that discipline will be tested.
• Q2 guidance: The Hankyung analysis piece in the cluster flagged that further Q2 improvement depends on memory-price trajectory rather than volumes.
