Samsung Q3 2026 Earnings Preview: DRAM +20%, Record Margins, and the Buyback Question
Samsung Q3 2026 Earnings Preview: DRAM +20%, Record Margins, and the Buyback Question
Three months ago, Samsung reported Q2 2026 operating profit of 89.4 trillion won — the most profitable quarter in the company's 55-year history. The stock fell 6%.
That precedent — extraordinary results met with selling — is the most important context for how to interpret Q3 expectations. The market has already moved on from "can Samsung beat records?" to "can Samsung beat expectations that have been raised dramatically since Q2?" Understanding the distinction is the key to positioning correctly around this earnings release.

The Three Catalysts Behind Q3's Expected Leap
① DRAM Prices Up 20% QoQ — The Core Driver
Industry sources confirmed last week that Samsung is negotiating with customers to raise average DRAM selling prices by up to 20% quarter-on-quarter for Q3. This pricing dynamic is the single most important input to Q3 operating profit — and it is significantly stronger than what most analysts had modeled entering the quarter.
To understand the scale: Samsung's Q1 2026 DRAM ASPs were already up approximately 30% QoQ from Q4 2025. Q2 saw continued pricing strength. A further 20% QoQ increase in Q3 compounds on an already elevated base — driving the revenue and margin expansion reflected in consensus estimates.
The supply constraint enabling this pricing is structural, not cyclical. Analysts have increased Q3 HBM revenue estimates by 15.5% and FY2026 forecasts by 22.8%, reflecting greater confidence in Samsung's AI memory roadmap. The combination of conventional DRAM ASP increases and HBM revenue ramp creates a dual pricing tailwind that explains the 27% QoQ operating profit growth expected in Q3.
② HBM Recovery — Samsung's Most Important Competitive Development
Samsung's HBM story in 2025 was one of setbacks: yield challenges on HBM3E delayed NVIDIA qualification, allowing SK Hynix to capture 56%+ of the global HBM market. In 2026, that story is reversing.
Samsung became the first company to achieve HBM4 mass production in February 2026. Q2 HBM4 sales surpassed $1 billion. Q3 HBM revenue estimates have been raised 15.5% since Q2 results, reflecting greater confidence in Samsung's AI memory roadmap.
For Q3, three HBM-related data points will be critical:
- HBM mix percentage: What share of Q3 memory revenue came from HBM vs conventional DRAM? An increase above Q2's level signals continued market share recovery.
- NVIDIA Vera Rubin qualification status: Any confirmation that Samsung has secured meaningful HBM4 allocation for NVIDIA's next-generation GPU platform would be a major positive signal.
- HBM4E timeline: Samsung's custom HBM4E design was targeted for mid-2026 customer sampling. Any update on customer reception would inform 2027 estimates.
③ Foundry Recovery — The Underappreciated Upside
Samsung Foundry has been the company's most problematic division for the past two years — losing market share to TSMC and reporting operating losses. In Q3, early signals suggest this trend is beginning to reverse.
Samsung's Q3 profits are expected to surpass market expectations, driven primarily by rising chip prices and a significant reduction in losses from its foundry business. Any foundry division improvement — even moving from large losses to smaller losses — would provide an additional earnings boost beyond what the memory division alone delivers.
The foundry recovery matters structurally because it represents a genuine earnings diversification beyond the AI memory cycle. A Samsung that generates strong profits from both memory and foundry is a structurally different — and more valuable — company than one dependent on memory alone.
What Q3 Numbers Mean in Historical Context
According to recent three-month consensus estimates, Q3 revenue is expected at 207.8 trillion KRW and operating profit at 113.6 trillion KRW, with operating margin forecast at 54.7%.
To put 113.6 trillion KRW in context:
- Samsung's previous all-time quarterly operating profit record was Q2 2026's 89.4 trillion KRW — itself 4.5x the prior all-time record
- Q3 consensus of 113.6 trillion KRW would exceed Q2 by 27% — implying the supercycle is accelerating, not peaking
- Full-year 2026 consensus of 374+ trillion KRW would, as Samsung's own DS Division President stated, exceed the cumulative semiconductor profits generated over Samsung's entire 40-year history in the chip business
- KB Securities projects Samsung will generate total operating profit of 327 trillion KRW in 2026 and 488 trillion KRW in 2027 — which would make Samsung the most profitable company in the world.
The Buyback Question: When Does Samsung Announce?
The most anticipated non-earnings development for Samsung investors is the potential buyback announcement. Following SK Hynix's 40 trillion won buyback and cancellation — the largest in Korean corporate history — Samsung has been under sustained pressure from investors to announce a comparable program.
Market expectations have coalesced around a 90–100 trillion won figure. Daishin Securities estimated Samsung would approve a shareholder return policy "on the order of 100 trillion won," characterizing it as a major catalyst that would act as "upward pressure on semiconductors and the domestic stock market overall."
The timing question is whether Samsung announces alongside Q3 preliminary results (this week) or separately. Three scenarios:
| Scenario | Buyback Scale | Timing | Market Impact |
|---|---|---|---|
| Bull Case | 90–100T KRW | With Q3 results this week | Massive rally — combined earnings + buyback catalyst |
| Base Case | 60–80T KRW | Separate announcement in October | Positive — below expectations but still historic |
| Bear Case | Below 50T KRW or delayed | Q4 or 2027 | Disappointment — "sell the news" risk |
For context: SK Hynix's 40 trillion won buyback drove a 12.73% single-day gain. A Samsung buyback of 90–100 trillion won — 2.25x the size — would represent an even larger structural signal for Korean corporate governance reform, potentially driving a meaningful re-rating of the KOSPI's Korea Discount.

The 5 Things to Watch This Week
① Q3 Operating Profit vs 113.6T KRW Consensus
The headline number determines initial market reaction. The critical thresholds:
- Above 120T KRW: Significant beat — "peak earnings" narrative definitively buried; KOSPI 8,000+ likely
- 113–120T KRW (in-line): Attention shifts entirely to buyback announcement and Q4 guidance
- 100–113T KRW (soft miss): Initial selling likely — watch management commentary on DRAM pricing trajectory
- Below 100T KRW: Meaningful correction — fundamental reassessment required
② Q4 and Full-Year Guidance Language
For Q3 2026, revenue expectations were raised 2.9% to 211 trillion KRW following Q2 results, while full-year 2026 revenue estimates were raised 2% to 742 trillion KRW. Any management commentary suggesting Q4 will be sequentially stronger — or weaker — than Q3 will drive significant analyst estimate revisions.
③ Foundry Division Update
Full divisional results (as opposed to preliminary consolidated figures) come with the detailed earnings release. The DS Division breakdown — separating memory from foundry — will reveal whether foundry losses are shrinking as expected. Any positive foundry surprise would be a genuine upside catalyst that consensus has not fully priced.
④ Buyback Announcement Timing and Scale
If Samsung accompanies the preliminary results with a buyback announcement, the combined catalyst — record earnings + historic buyback — would be unprecedented in Korean market history. Watch for any Board of Directors disclosure filings alongside the earnings announcement.
⑤ DRAM Pricing Commentary
The +20% QoQ negotiation news is market intelligence, not an official announcement. Management's commentary on the Q3 DRAM pricing environment — and whether it expects Q4 to maintain or extend the pricing tailwind — is the most forward-looking fundamental data in the entire earnings package.
Beyond Semiconductors: Why Q3 Is Also a Broader Korean Market Story
KOSPI-listed companies' aggregate Q3 operating profit estimates are expected to reach 278.8 trillion KRW — a 234.6% increase from the same period last year. The semiconductor industry's operating profit is forecast to surge from 26.9 trillion KRW in the prior year to 205.1 trillion KRW. But non-semiconductor companies' Q3 operating profit is also expected to rise 32.4%, reaching 74.7 trillion KRW.
This broadening of earnings recovery beyond semiconductors — Samsung SDI's battery division up 269%, SK Innovation up 87%, Korean Air up 48% — is the structural development that enables the KOSPI's path to 10,000. The index cannot sustain a re-rating to fair value on semiconductor earnings alone. When defense, energy, automotive, and financial stocks also deliver strong Q3 results, the KOSPI re-rating becomes self-reinforcing across sectors.
The Samsung vs SK Hynix Q3 Comparison
Samsung and SK Hynix will both report Q3 results within weeks of each other — Samsung first (preliminary this week), SK Hynix at its earnings call in late October. Comparing the two provides the most complete picture of the Korean semiconductor market's health.
| Metric | Samsung Q3 2026E | SK Hynix Q3 2026E |
|---|---|---|
| Operating Profit | 113.6T KRW (consensus) | 77T KRW (KB Securities) |
| YoY OP Growth | +770% | +579% |
| Operating Margin | 54.7% | ~75%+ (HBM-driven) |
| Key Story | DRAM +20%, HBM recovery, foundry turnaround | HBM4 ramp, LTA pricing, additional buyback details |
| Buyback | 90–100T KRW expected (not yet announced) | 40T KRW announced; additional details at earnings |
| SKHY / ETF Impact | Indirect — Samsung not listed on Nasdaq; held via EWY/FLKR | Direct — SKHY holders receive full benefit |
What This Means for Global Investors
If you hold Korea ETFs (EWY / FLKR):
Samsung accounts for approximately 20–25% of EWY. A Q3 operating profit of 113.6 trillion won — confirming the H2 acceleration thesis — would be a direct positive catalyst for Korea ETF positions. The additional broadening of earnings beyond semiconductors (32.4% growth in non-semiconductor KOSPI earnings) reduces concentration risk and supports a more durable KOSPI recovery. Hold through the results and watch for buyback announcement as the next catalyst.
If you hold SKHY:
Samsung's Q3 results provide important context for SK Hynix's own late October earnings call. If Samsung confirms DRAM +20% QoQ pricing and strong HBM momentum, SK Hynix's Q3 of 77 trillion won (consensus) becomes more credible — and the additional shareholder return announcement in late October becomes more anticipated. A strong Samsung Q3 is a positive leading indicator for SKHY.
If you are considering new positions:
The window before Samsung Q3 results — and before SK Hynix's additional buyback announcement — offers entry at KOSPI levels still well below analyst fair value estimates. The KOSPI's forward PER remains at approximately 5.5–6x despite the October 3 rally. At consensus earnings for 2026 and 2027, this valuation gap is difficult to justify fundamentally.
Final Thought: The Supercycle Is Not Over
When Samsung's own DS Division President says 2026's profit alone will exceed 40 years of cumulative semiconductor earnings — and when Q3 consensus calls for 27% QoQ growth on top of a record Q2 — the "peak earnings" narrative looks increasingly disconnected from reality.
Goldman Sachs projects earnings expansion of 320% during 2026, succeeded by an additional 35% increase throughout 2027. KB Securities projects Samsung's 2027 operating profit at 488 trillion won — which would make it the most profitable company in the world. These are not fringe estimates. They reflect the compound effect of DRAM pricing power, HBM volume growth, and AI infrastructure spending that is now forecast to reach $1.5 trillion annually by 2028.
Q3 results this week are the next major data point confirming — or challenging — this trajectory. Based on every available indicator, confirmation is the far more likely outcome.
