Context This is a follow-up to FADU as Korea’s Sandisk beta, FADU’s P, Q and new-segment test, Korean semiconductor Top 50 two-month alpha candidates and the HBF/HBC commercialization calendar. FADU should be analyzed as an eSSD controller and AI-storage bottleneck name, not as a confirmed HBF beneficiary.
TL;DR
My FADU 2Q26 estimate is KRW 69-72B revenue and KRW 11-12.5B operating profit. The midpoint is KRW 70.5B revenue, KRW 11.8B operating profit and 16.7% operating margin.
The local consensus snapshot as of July 3, 2026 shows 2Q26 revenue of KRW 60.5B and operating profit of KRW 9.3B. The midpoint estimate is 16.5% above revenue consensus and 26.9% above operating-profit consensus. A beat is likely, but this is not a mega-surprise bar.
The key is not the gross amount of 2Q contract disclosures. Major supply contracts disclosed during the quarter total about KRW 150.8B. A mechanical pro-rata allocation would imply roughly KRW 35.4B of 2Q exposure. But amended disclosures in June pushed some contract end dates and payment terms later. Treating the full pro-rata amount as incremental 2Q revenue would be too aggressive. A more reasonable 2Q incremental recognition range is KRW 9.5-12.5B.
The stock call is Wait. FADU closed at KRW 79,600 on July 3, 2026, implying roughly KRW 3.98T market cap. Against FY2026E revenue of KRW 301.5B and operating profit of KRW 44.8B, that is about 13.2x sales and 89x operating profit. At this valuation, a good 2Q print is not enough. Investors need evidence of second-half delivery normalization, backlog conversion and controller-mix durability.
0. Setup
| Item | Detail |
|---|---|
| Company | FADU |
| Ticker | 440110 / KOSDAQ |
| Analysis date | 2026-07-04 KST |
| Price basis | July 3, 2026 close, KRW 79,600, local KR database |
| Consensus basis | July 3, 2026 local consensus snapshot, 2Q26 revenue KRW 60.5B, OP KRW 9.3B |
| Main question | How much of the 2Q contract disclosures can actually be recognized as 2Q revenue? |
| Stance | Wait; conditional entry after proof |
This preview uses public filings, public media reports and local market data. It does not use private management color.
1. Baseline From 1Q26
| Metric | 1Q26 |
|---|---|
| Revenue | KRW 59.54B |
| Operating profit | KRW 7.69B |
| Net income | KRW 10.21B |
| SSD controller revenue | KRW 47.9B |
| SSD controller mix | 80.4% |
| SSD finished-product revenue | KRW 9.9B |
| SSD finished-product mix | 16.6% |
The important point is mix. FADU earns a higher-quality multiple only if it is seen as an eSSD controller and firmware bottleneck company, not as a finished-SSD assembler. The 1Q controller mix of 80.4% is therefore more important than the headline profit turn.
The reported 1Q gross profit was KRW 34.65B. Against revenue of KRW 59.54B, this implies a 58.2% gross margin. Subtracting KRW 7.69B operating profit gives implied SG&A of about KRW 26.96B.
| Item | Formula | Value |
|---|---|---|
| 1Q gross margin | 34.65 / 59.54 | 58.2% |
| Implied 1Q SG&A | 34.65 - 7.69 | KRW 26.96B |
| 1Q operating margin | 7.69 / 59.54 | 12.9% |
2. Backlog And 2026 Delivery Base
FADU’s 1Q-end backlog was reported at $116.208M, roughly KRW 175.9B. The 2026 delivery portion was $95.131M, roughly KRW 144.0B. Adding 1Q revenue gives a visible annual revenue base above KRW 200B, before the rest of the 2Q disclosures.
| Item | Amount |
|---|---|
| 1Q-end backlog | $116.208M |
| KRW equivalent | ~KRW 175.9B |
| 2026 delivery portion | $95.131M |
| KRW equivalent | ~KRW 144.0B |
| 1Q26 revenue | KRW 59.54B |
The caveat is timing. A 2026 delivery commitment does not mean 2Q recognition.
3. 2Q Contract Disclosures
| Disclosure timing | Product | Contract amount | Contract period | Pro-rata 2Q exposure |
|---|---|---|---|---|
| Apr 13 | Enterprise SSD controller | KRW 15.196B | Apr 10-Oct 9 | ~KRW 6.8B |
| May 6 | Enterprise SSD controller | KRW 50.012B | May 5-Dec 8 after amendment | ~KRW 13.1B |
| May 22 | Enterprise SSD controller | KRW 28.684B | May 21-Dec 11 | ~KRW 5.7B |
| May 28 | eSSD controller | ~KRW 46.5B | May 28-Jan 1, 2027 | ~KRW 7.2B |
| May 29 | Finished SSD | KRW 10.373B | May 28-Oct 11 | ~KRW 2.6B |
| Total | ~KRW 150.8B | ~KRW 35.4B |
The June amendments matter. The KRW 50B contract end date moved from Nov. 13 to Dec. 8, and payment terms moved from the next Friday after delivery to within 30 days after delivery. A separate KRW 20.3B controller contract was also extended from June 12 to July 17. These do not prove demand weakness, but they do weaken the 2Q cutoff.
4. Revenue Model
| Component | Estimate |
|---|---|
| 1Q revenue baseline | KRW 59.5B |
| Incremental 2Q recognition from new contracts | +KRW 9.5-12.5B |
| Finished products and other movement | +/- KRW 1.0B |
| 2Q26 revenue estimate | KRW 69-72B |
| Midpoint | KRW 70.5B |
This is more conservative than the earlier June framework that looked for KRW 90-105B of 2Q revenue. The reason is new information: amended disclosures increased the risk that part of the revenue recognition slips into 3Q.
5. Operating Profit Model
| Segment | Revenue assumption | Gross margin assumption | Gross profit |
|---|---|---|---|
| Controllers | KRW 57.5B | 61% | KRW 35.1B |
| Finished SSD / modules | KRW 11.0B | 15% | KRW 1.7B |
| Other | KRW 2.0B | 50% | KRW 1.0B |
| Total | KRW 70.5B | ~53.5% | ~KRW 37.7B |
Using KRW 25.9B of SG&A, the midpoint operating profit is about KRW 11.8B, or a 16.7% margin. The implied 2Q gross margin is below 1Q’s 58.2% to reflect finished-product mix and cutoff risk.
6. Scenario Table
| Scenario | Revenue | Operating profit | OPM | Interpretation |
|---|---|---|---|---|
| Bear | KRW 62-65B | KRW 9-10.5B | 14.5-16.2% | In line to slight beat |
| Base | KRW 69-72B | KRW 11-12.5B | 15.9-17.4% | Clear beat |
| Bull | KRW 78-83B | KRW 14.5-17B | 18.6-20.5% | Major surprise |
Base is the central case. Bull requires faster shipment, limited impact from amendments and controller mix near 80%.
7. Consensus Bar
| Metric | Consensus | Midpoint estimate | Delta | Delta % |
|---|---|---|---|---|
| Revenue | KRW 60.5B | KRW 70.5B | +KRW 10.0B | +16.5% |
| Operating profit | KRW 9.3B | KRW 11.8B | +KRW 2.5B | +26.9% |
| OPM | 15.4% | 16.7% | +1.3ppt |
A meaningful beat needs revenue above KRW 70B and OP above KRW 11.5B. A true estimate-reset print likely needs revenue above KRW 75B and OP above KRW 14B.
8. Price, Flow And Valuation
| Item | Value |
|---|---|
| July 3 close | KRW 79,600 |
| 5D return | -4.1% |
| 20D return | -27.5% |
| 60D return | +57.9% |
| Estimated market cap | ~KRW 3.98T |
| 20D foreign net buying | ~KRW 227.3B |
| 20D institutional net selling | ~KRW -117.6B |
| Foreign ownership | 24.11% on Jun 8 to 28.25% on Jul 3 |
Foreign flow is the positive signal. Institutional confirmation is not there yet. On valuation, FY2026E revenue of KRW 301.5B and OP of KRW 44.8B imply about 13.2x sales and 89x operating profit. This is not cheap. It requires continued proof.
9. Entry, Catalysts And Falsifiers
| Action rule | Requirement |
|---|---|
| Earnings-confirmation entry | 2Q revenue above KRW 70B, OP above KRW 11.5B, controller mix near 80% |
| Strong-beat entry | Revenue above KRW 75B, OP above KRW 14B |
| Valuation entry | If the print is only moderate and the stock derates toward below KRW 3.0T market cap or below 10x FY2026E sales |
Catalysts are the 2Q result, 2Q-end backlog, 2026 delivery update, controller mix, normalization of amended contracts and 3Q revenue acceleration.
Falsifiers are revenue below KRW 65B, OP below KRW 10B, controller mix below 75%, gross margin below 50%, further delays in the KRW 50B or KRW 20.3B contracts, no 3Q backlog-conversion guide, or continued dependence on two customers near 80%.
Final View
FADU probably beats consensus in 2Q26. My midpoint is KRW 70.5B revenue and KRW 11.8B operating profit. But this is a moderate beat, not a clean buy signal at any price.
FADU remains a valid AI-storage bottleneck candidate. The stock needs stricter evidence now: 2Q revenue above KRW 70B, controller mix near 80%, and proof that delayed contracts convert into 2H revenue.
