Rating: Cautious Bearish | Target Price: CNY 175–215 (base-case fair value) | Current Price: CNY 280.00 (2026-09-01 close) | Margin of Safety: -37.5% (base-case fair value floor of CNY 175 vs current price) | Time Horizon: 12 months
| Item | Previous (2026-07-04, anchor CNY 410.60) | This Update (2026-09-02, anchor CNY 280.00) | Driver of Change |
|---|---|---|---|
| Stance | Cautious bearish | Cautious bearish (maintained) | After a 31.8% price pullback, the degree of overvaluation has narrowed, but the price still sits 30%–60% above base-case fair value; direction unchanged |
| Confidence | 0.65 | 0.60 | Divergence with the market has narrowed (-82% → -35%), so conviction in direction realization is correspondingly reduced |
| Target price range | CNY 50–80 | CNY 175–215 | Optical communication revenue realization far exceeded prior assumptions (previously expected full-year increment of CNY 200–300 million; actual H1 already CNY 166 million); Yuanjie Semiconductor's profit realization validates the industry's profitability model and the real existence of an A-share scarcity premium; Q2 marked the first positive single-quarter recurring profit |
| Valuation verdict | Bubble | Overvalued | Previously the price was above the bull-case ceiling (410 > 200); now the price falls within the bull-case range (250–330), i.e., a "pre-priced bull case" rather than "surpassing all scenarios" |
In one sentence: the direction of the conclusion is unchanged, but the coordinates have shifted — fundamentals are better than two months ago (optical communication volume up 4.4x, Q2 recurring profit turned positive), and the stock is 32% cheaper than two months ago. Yet at CNY 280, the market is pricing in the entire 2030 optimistic scenario in advance; the risk/reward remains insufficient.
Everbright Semiconductor is a scarce domestic semiconductor laser chip IDM platform. The demand inflection for AI data center optical interconnects is real and strong: 800G-and-above optical module shipments in 2026 are expected to grow +163%; the industry-wide shortage of high-speed EMLs is roughly 30%; domestic substitution for optical chips above 25G is only ~4%; the company's optical communication revenue reached CNY 166 million in 2026H1 (4.4x of full-year 2025, 42.5% of revenue), and Q2 single-quarter recurring profit turned positive for the first time at +CNY 1.18 million.
But "the direction is right" does not mean "the price is right." The current price of CNY 280 corresponds to a market cap of CNY 49.36 billion, P/S (TTM) of 75.4x, and P/B of 16.2x (92nd percentile over the past 5 years), while recurring earnings remain negative on a TTM basis and the 2026E consensus net profit attributable to shareholders is only ~CNY 78 million (implying a P/E of ~636x). Reverse engineering shows that discounting the current price back at a 2030 exit P/E of 30–40x requires 2030 net profit of CNY 1.81–2.41 billion (a 4-year CAGR of +122%~138%) and a global EML share of 14%–29% (exceeding Lumentum's current annual capacity). Even under the aggressive but attainable path of "domestic substitution from 4% to 30% × the company capturing 40% of the domestic share," the implied value is only about CNY 182 per share. Base-case 12-month fair value is CNY 175–215; the current price is 30%–60% above it, with no margin of safety. Additional catalysts for valuation normalization include: optical communication gross margin of only 10.93% (vs. Yuanjie's 80.4% over the same period), a single customer (Customer F) accounting for 86.5% of that segment, insiders persistently net selling, and the lifting of major shareholder sell-down restrictions from 2027. The key constraint is: Yuanjie's current 139.7x P/S valuation suggests the A-share scarcity premium may not normalize for a long time, and the path to normalization could be volatile.
(Ratings and real-time risk/reward are computed by the system uniformly based on the three scenarios and price; this section does not display an artificial composite score.)
Key evidence:
Q2 single-quarter breakdown: revenue CNY 261 million (+101% QoQ), net profit attributable to parent CNY 25.86 million, recurring profit +CNY 1.18 million — the turnaround barely crosses breakeven, and the same quarter also contains offsetting noise from CNY 15.55 million of impairment provisions. The company attributes the strong revenue growth to "rapid growth of the previously deployed optical communication business" and the cash flow deterioration to "increased optical communication inventory" — both explanations point to the same fact: the growth is real, but it is currently achieved at the cost of gross margin and cash.
Key evidence:
Current price position: scenario distribution is bear CNY 70–105 (30%) / base CNY 175–215 (50%) / bull CNY 250–330 (20%), with a probability-weighted fair value of ~CNY 182; at CNY 280, the price is inside the bull-case range and ~54% above the weighted fair value. Relative to the current price: to base-case midpoint CNY 195, -30.4%; to base-case floor CNY 175, -37.5%; to bear-case midpoint CNY 87.5, -68.8%; to bull-case midpoint CNY 290, +3.6% — the odds are significantly asymmetric to the downside. The counterevidence that must be stated candidly: Yuanjie Semiconductor currently trades at P/S (TTM) of 139.7x with a market cap of CNY 184.5 billion, suggesting the A-share sector scarcity premium may persist long term, introducing uncertainty in the path and timing of valuation normalization.
Key evidence:
Offsetting information must be presented side by side: the company is fully in free float, with no future unlock batches and a 0% pledge ratio; the new board secretary / CFO took office in May 2026; in 2026Q1, public funds such as AVIC Opportunity Navigator entered the top ten shareholders (institutional contrarian buying coexists with sell-downs). Overall, however, the combination of "nobody buying, everyone having sold, rapid retail-ization of the register" is a persistent discount factor for a high-valuation stock. The 28% figure above is the potential sellable overhang cap after constraints expire, not a stated sell-down plan.
Key evidence:
Industry demand math (see industry section): 800G+ optical modules from 24 million units in 2025 to ~63 million units in 2026E (+163%); global EML demand from ~96 million units in 2025 to ~250 million units in 2026E; the company's implied share (revenue ÷ ASP) rises from ~1% to ~3–5%. The demand is real, and the share climb is real — what is missing is profit: in the same track, Yuanjie Semiconductor posted 2026H1 revenue of CNY 925 million (+351%), net profit of CNY 607 million, and gross margin of 80.4%, proving this business has a high profit ceiling — and also proving that between Everbright Semiconductor and the proven winner lies the full leap from "concession-priced design-in" to "market-price pricing + in-house replacement of semi-finished products."
| Metric | FY2023 | FY2024 | FY2025 | 2025H1 | 2026H1 (latest) |

Note: The company does not disclose Non-GAAP/adjusted figures; this table uses recurring net profit (excluding fair value changes, government grants, and other one-off items). The 2026H1 gap between recurring and attributable net profit of CNY 40.72 million is entirely from non-recurring items.
Drivers of metric changes (line items with YoY ≥ ±20%, with company explanations): Operating revenue +82.67% — company explains "rapid growth of the previously deployed optical communication business"; operating cost +105.01% (faster than revenue, driving gross margin -8.2pp) — "revenue increased and costs increased correspondingly"; operating cash flow outflow increased by CNY 129 million YoY — "sharp growth in optical communication revenue and higher inventory stocking increased cash paid for purchases of goods"; accounts receivable +54.68% vs. beginning of year — "due to revenue growth"; inventory +39.89% — "higher business volume, materials stocking"; other receivables +674.36% — new CNY 11 million investment intention deposit in Shanghai Feibo Laser; long-term equity investments +35.73% — CNY 105 million capital increase in Xingyue Photonics, CNY 45 million in Photonics Fund Phase II, etc.; other non-current financial assets +98.56% — capital increase in the Photonics Fund, whose fair value gain of CNY 24.69 million was the main source of attributable net profit; finance costs swung from -CNY 20.07 million to +CNY 0.46 million — a high base of large CD interest income in the prior-year period.
1. Business model snapshot: Asset-heavy IDM — full in-house flow from epitaxial growth → wafer fab → cleaving and coating → packaging and testing, with 2/3/6-inch production lines covering five material systems (GaAs/InP/GaN/SiC/silicon photonics); revenue comes entirely from chip/device/module hardware sales, with no recurring revenue. Downstream customers are fiber laser manufacturers (Raycus, Maxphotonics, etc.) and optical module makers; customer qualification cycles run 2–12 months with high stickiness. Weak pricing power: in optical communication, concessionary pricing to top-tier customers (import price of USD 5.5 per chip, further discounted); high-power single-emitter unit price is only about RMB 12 per unit, barely rising.
2. Cash content of earnings: OCF/net profit attributable to parent for 2023–2025 was -0.27 / 0.66 / 1.00, deteriorating to -5.18 in 2026H1; FCF/attributable profit in 2026H1 was -6.49 (FCF of -RMB 197 million). 2025, the only year with positive OCF, was barely breakeven on a low base; 2026H1 saw massive cash bleed resume — reported profits currently generate no discretionary cash at all. Recurring earnings test: non-GAAP (excluding non-recurring items) has been negative for three and a half consecutive years (-112 / -146 / -33 / -10 million RMB); in 2026H1, the gap between attributable profit and non-recurring gains/losses exceeded 100% — book profit is propped up by photonics fund valuation and subsidies; excluding these, the core business remains loss-making.
3. Return on capital: ROIC of roughly 0.84% (pre-tax total basis; negative on non-GAAP basis), far below the cost of capital — current "growth" creates no economic profit; all value hinges on future gross margin recovery.
4. Maintenance CapEx: 2026H1 CapEx of RMB 39.81 million / D&A of RMB 51.22 million ≈ 0.78 — a capacity digestion period rather than an expansion black hole; but equity investments in the same period totaled RMB 158 million (Xingyue/Photonics Fund, etc.), more than 4× core-business CapEx. Capital has shifted from production lines to equity platforms, with longer payback periods and lower visibility.
5. Moats and red flags: The moat genuinely lies in the process platform (CAS-affiliated full-flow IDM, China's only 6-inch high-power volume production line) and qualification barriers; red flags are equally concrete: top five customers account for 50.5% of sales, Customer F accounts for 86.5% of the optical communication segment (2025); the associate companies portfolio keeps bleeding (2025: 10 companies with combined net profit of -RMB 33.66 million; H1 equity-method loss of -RMB 6.55 million); RMB 42 million receivables from Customer A2 hung on the books for years, settled via mediation at a discount to RMB 32.18 million in installments through end-2028; RMB 60 million of wealth-management products at Zhongrong Trust overdue, fully provisioned.
1. Words-vs-actions consistency — "partially delivered, key promises not delivered": ① The inquiry letter (2026-07) promised three gross-margin improvements in optical communication → 2026H1 segment gross margin continued falling to 11.68% (not delivered); ② The 2025 annual report promised bulk delivery of optical communication orders → H1 revenue up 4.4× (delivered); ③ "Improve shareholder return mechanisms, formulate a reasonable dividend plan" (quality-and-efficiency program) → no interim distribution; undistributed profit of -RMB 35.54 million makes dividends objectively impossible (not delivered but constrained); ④ Capacity-expansion messaging remains cautious and vague (interaction platform: "evaluate prudently based on customer demand," no timetable), coexisting in parallel with capacity publicity (EML monthly output of 4–6 million units by end-November). Overall verdict: positive technology narrative, cautious financial framing, patchy promise delivery, with a preference for letting the market fill in the blanks.
2. Shareholder friendliness — neutral to weak: Since listing, cash dividends only in 2022 (RMB 47.46 million); no distributions for three consecutive years 2023–2025; a repurchase of ~RMB 34.66 million of treasury stock in 2024 with no follow-up; IPO proceeds of RMB 2.739 billion (oversubscribed by RMB 1.188 billion) fully used, with RMB 1.248 billion of oversubscription permanently converted to working capital — capital taken from the market far exceeds capital returned; the only bright spot: no follow-on dilution.
3. Risk signals: Warned twice by the Jiangsu CSRC bureau in 2023 (oversubscribed funds in wealth-management products not redeemed timely; raised funds returned to non-dedicated accounts); the 2025 annual report drew an SSE inquiry (record Q4 revenue with net profit of only RMB 820k, abnormal gross-margin swings, gross-revenue recognition, plus receivables and inventory — four major issues); Board Secretary changed multiple times within 19 months; CFO seat vacant for over 5 months until filled in May 2026 (the inquiry response disclosed that key-position turnover constitutes a significant internal-control deficiency at the non-financial-reporting level; the annual internal-control audit opinion was a standard unqualified one); the Chairman and core executives collectively net-sold (zero buys) in the RMB 159–225 range between February–April 2026. The range where insiders voted with their feet sits at 40–60% of today's price.
| Segment (2026H1) | Revenue (RMB 100M) | Share | Gross margin | Gross profit contribution | Business logic in one line |
|---|---|---|---|---|---|
| High-power single-emitter series | 1.95 | 49.9% | 30.1% | 59.8% | The base: standardized industrial laser pump sources, stable volume, flat pricing |
| Optical communication chip series (EML/DFB/PIN) | 1.66 | 42.5% | 10.9% | 18.5% | Growth engine: AI datacom 0→1 introduction phase, trading margin + outsourced semi-finished parts for share |
| High-power bar series | 0.10 | 2.6% | 52.6% | 5.5% | Custom project-based (research/specialty/medical), high margin, small scale |
| VCSEL series | 0.03 | 0.75% | 54.1% | 1.6% | Automotive LiDAR/3D sensing; multiple parts passed AEC-Q102, awaiting volume ramp |
| Others (modules/research, etc.) | ~0.17 | ~4.3% | — | ~14.6% | Devices and research support |
The profit engine remains high-power single emitters (49.9% of revenue but 59.8% of gross profit); optical communication contributes only 18.5% of gross profit on 42.5% of revenue — this mismatch ("second revenue pillar, fifth-ranked profit contributor") is the root of today's valuation dispute. Gross-margin spread across segments exceeds 40pp (bars/VCSEL at ~53–54% vs optical communication at 10.9%): the former is custom small-batch with high bargaining power, the latter is concessionary pricing to anchor customers plus outsourced semi-finished parts (materials are 96.83% of cost) — the premise for optical communication margin recovery is in-house substitution of outsourced parts and market-price contracts with new customers; both were promised in the inquiry response but remain undelivered in the H1 financials.
Accounting red flags (by severity):
Cross-period consistency: Overall gross margin series 2023–2026H1: 33.5%→23.9%→34.5%→25.1% (two jumps of 8–11pp, attributed to mix effects, consistent with management explanations); non-GAAP profit series: -1.12→-1.46→-0.33→-0.10 hundred million RMB (direction of improvement consistent, but the company has never answered when the core business will turn profitable); the OCF/attributable profit series is self-consistent with the "stockpiling expansion" explanation. Overall judgment: no signs of systematic accounting fraud, but clear traces of engineered earnings quality (fair value + subsidies + R&D cuts); regulatory inquiry attention has become institutionalized.
1. Current market data (close of 2026-09-01): Share price RMB 280.00, market cap RMB 49.36 billion. PB of 16.2× (92nd percentile of the past 5 years, unsupported by 2025 ROE of only 0.73%); PS(TTM) of 75.4× (TTM revenue RMB 654 million); PE(TTM) in the thousands but earnings are unrepresentative (TTM non-GAAP about -RMB 32 million) — PE percentile is context only, not evidence of cheapness or richness; 2026E/2027E forward PE of ~636×/322×, PEG of ~3.5–7.0. Peer comparison:
| Company | Market cap | PS(TTM) | 2026E PE | Revenue growth | Gross margin / ROE | Key difference |
|---|---|---|---|---|---|---|
| Everbright Xin (长光华芯) | RMB 49.36B | 75.4x | ~636x | H1 +82.7% | 25.1% / 0.7% (2025) | Full-stack IDM but profitability undelivered |
| Yuanjie Semiconductor | RMB 184.5B | 139.7x | ~142x | H1 +351% | 80.4% / 22.2% (H1) | CW light source riding the silicon photonics wave, profitability delivered (H1 net profit RMB 607M) |
| Shijia Photons | RMB 68.16B | 25.9x | ~101x | H1 +50.7% | 36.2% / 19.3% (H1) | Passive platform, profits delivered |
| Lumentum | ~RMB 551.6B | 27.2x | 41.8x (FY27E) | FY26 +83% | 50.4% (Non-GAAP) | Global EML leader, capacity locked by NVIDIA |
| Coherent | ~RMB 358.9B | 8.1x | 29.0x | FY26 +22.5% | 37.5% / 8.5% | Full-chain giant from substrate to module |
2. What the market already implies: Backing out from a RMB 49.36B market cap at an exit PE of 30×/40× in 2030 with 10% discounting requires 2030 attributable net profit of RMB 1.81–2.41 billion — today's price requires the company to go from non-GAAP breakeven to earning roughly RMB 2 billion a year within 4 years, capture 14%–29% of global EML demand (exceeding Lumentum's current ~90 million units/year output), and lift net margin from ~0 to 25%–30%. Reality: share of ~1%→3–5% (estimated), optical communication gross margin of 10.93%, no 200G anchor-customer orders yet. Two-sided demand check: AI demand is real and strong (capex USD 610–760 billion, EML shortage of 30%), but even on an aggressive-but-attainable path of "domestic substitution rate 4%→30% × company's 40% share of domestic demand × ASP RMB 55 × net margin 25%," 2030 net profit would be ~RMB 1.17 billion, discounting to ~RMB 182/share — the implied expectation materially exceeds the verifiable path: right direction, overdrafted odds.
3. Three layers of value: Asset value ~RMB 13.1/share (net cash of RMB 6.06 + fixed assets and CIP of ~RMB 608M converted per share; book NAV of RMB 17.3/share as the ceiling); EPV with zero growth ~RMB 6.6/share (normalized EPS of RMB 0.05 — 2026E non-GAAP breakeven basis, WACC 10%); the growth option accounts for ~97.7% of the current price. For a growth stock at a structural inflection, EPV is the floor, not the conclusion — but here even the "aggressive path discounted value of RMB 182" sits 35% below the current price, indicating the price buys not the 2030 bull case but a double dose of optimism: "bull case pulled forward + premium sustained."
4. Three scenarios and odds (12 months):
| Scenario | Probability | Fair-value range | vs current price | Decisive factor |
|---|---|---|---|---|
| Bear | 30% | RMB 70–105 | -62.5% ~ -75.0% | Inflection falsified: AI capex downgrades + EML supply release triggers price war + gross margin stuck at 10–15% + 200G qualification fails; anchored on PS 15–20x (2027E revenue RMB 850–900M) crossed with PB 4–6x |
| Base | 50% | RMB 175–215 | -23.2% ~ -37.5% | Optical communication revenue 2026/27/28 = RMB 420/750/1,200M, gross margin 10.9%→28%→35%; 2027E revenue RMB 1.21B × PS 26–30x (anchors: Shijia 25.9x / LITE 27.2x, independent of this company's current multiple); strict exit discounted value of ~RMB 102 as a floor indicator |
| Bull | 20% | RMB 250–330 | -10.7% ~ +17.9% | 200G mass production in Q4 + 2027 anchor orders, gross margin re-rating replaying Yuanjie's slope (48.8%→80.4% took 4 quarters), Xingyue interconnect; 2028E net profit RMB 460M × PE 90–110x (A-share scarcity premium band, between Yuanjie's 2026E 142x and LITE's forward 41.8x) |
Probability-weighted fair value ~RMB 182 (-35%). Own earnings forecasts (triangulated against management guidance and sell-side consensus): FY2026 revenue RMB 730–830M / attributable profit RMB 55–85M (consensus RMB 76–78M, Pacific Securities RMB 75M; no quantified management guidance); FY2027 revenue RMB 1.05–1.3B / attributable profit RMB 110–190M (consensus ~RMB 153M); FY2028 revenue RMB 1.4–1.8B / attributable profit RMB 230–360M (Pacific RMB 268M, prior consensus RMB 288M — no sell-side upgrades). The bull-case 2028E of RMB 460M exceeds all published forecasts, contingent on a 200G mega-order landing — this is precisely the gap between "price = bull case" and "published earnings = base case" pricing.
5. Conclusion: Overvalued. Target price range RMB 175–215 (= base case), margin of safety -37.5% (base-case fair-value floor RMB 175 vs current price RMB 280, per the system's unified convention). Separate quality from price: the business direction is real and the positioning scarce (quality earns a "narrative score"), but profit validation hasn't happened and the price has front-loaded the 2030 bull case (verdict on price: overvalued). The base-case exit multiple is anchored to peers with delivered profits — Shijia's PS 25.9x and global leader LITE's 27.2x (both independent of this company's current multiple); this company's current 75.4x PS is for comparison only and not used in anchoring.
1. Industry Size (Two Measurement Calibers, Listed Side by Side)
High-power semiconductor laser chips (the company's traditional core business, 87% of revenue in 2025, declining to about 52% in 2026H1): China's high-power semiconductor laser chip market was approximately RMB 1.83 billion in 2020 (company prospectus caliber, RMB); downstream China laser equipment market at approximately RMB 95.8 billion in 2025 (industry observation caliber, to be verified). The industry is characterized by maturity plus the tail end of a price war: volume up and prices down in 2023–2024, prices stabilizing in 2025 (company inquiry response caliber), downstream recovery (Raycus' 10,000-watt-class laser sales +26%, IPG's China revenue share falling to about 28%), with single-digit growth as the central tendency.
Optical communication laser chips (the growth engine, 42.5% of revenue in 2026H1): China's optical chip market at approximately RMB 6.6 billion in 2024 (+43.5%), approximately RMB 11.6 billion in 2026E; global AI datacom optical modules at USD 16.5 billion in 2025 → USD 26.0 billion in 2026E (LightCounting); global optical communication chipset market at approximately USD 3.5 billion in 2024 → over USD 11 billion in 2030E (CAGR ~17%); LightCounting estimates InP-based optical chips will account for 58% of the optoelectronics industry in 2025 and about 46% in 2031 (approximately USD 6.9 billion). Ethernet optical modules grew +93%/+82% in 2024/2025; LightCounting forecasts the optical module market at +65% in 2026, but turns conservative for 2027–2031 (15–20% range).
2. Quantified Chain of the Demand Inflection Point (Structural Re-Rating Thesis): Key drivers — the Big Four cloud providers' combined 2026 capex of approximately USD 610–760 billion (up ~70% YoY; in late August Meta raised its 2026 floor to USD 130 billion; NVIDIA's single-quarter revenue of USD 96.2 billion, +106%); unit consumption — the 800G (DR8/2×FR4) EML solution uses 8 × 100G EML per module, 1.6T DR8 uses 8 × 200G EML per module (speed upgrades rely on specs, not chip count), silicon photonics solutions use 1–2 CW light sources per module (power rising 70mW→100mW→300mW), and under the CPO form factor, InP consumption is roughly 3x; penetration ramp — 800G+ optical module shipments of 24 million units in 2025 → approximately 63 million units in 2026E (+163%, TrendForce); global EML demand of approximately 96 million units in 2025 → approximately 250 million units in 2026E (estimated under a 50% EML-solution share assumption); company share — 100G EML shipments of approximately 0.91–1.25 million units in 2025 (estimated from revenue × ASP, ~1% of the global market) → annualized 8.4–11.6 million units in 2026E (~3–5%). Conclusion: This is an industry-wide re-rating driven by exogenous demand (a double jump in unit value and total volume), not natural industry growth — valuation should anchor primarily on the growth caliber, with PE/PB percentiles serving only as a downside floor. But "industry re-rating" holds does not mean "any price is justified": an individual stock's market share and gross margin realization remain independent variables.
3. Value Chain and Value Distribution: Upstream InP/GaAs substrates + epitaxy equipment — China depends on imports for about 80% of InP substrates; 4-inch InP substrate averaged RMB 6,500/wafer in August 2026, +50% from the start of the year; refined indium up more than +80% (SMM) — bargaining power has shifted upstream, squeezing midstream gross margins; midstream laser chips are the thickest-margin segment (Yuanjie's 2025 gross margin 58.11%, Lumentum Non-GAAP 50.4%, Coherent 40.2% vs. 25–35% for the module/component segments); downstream optical module makers (Innolight/Eoptolink/T&S, with the vast majority of global high-speed optical modules supplied by Chinese vendors) → North American cloud providers/NVIDIA. Changguang Huaxin sits in the midstream chip layer as an IDM with in-house epitaxy-wafer fabrication, but its optical communication business currently operates on "margin-sacrificing customer introduction + purchased semi-finished products," and has yet to capture the thick chip-layer margin.
4. Supply-Demand and Competitive Landscape: Demand side as above; on the supply side, fewer than six players globally have effective high-speed EML capability (Lumentum/Coherent/Mitsubishi/Sumitomo/Broadcom); NVIDIA has locked in capacity from major suppliers with lead times pushed beyond 2027; the industry shortfall is roughly 30% (LightCounting, April 2026), and the overall InP substrate shortfall exceeds 70% (Omdia/Yole composite caliber). There is an authoritative divergence on the easing timeline: LightCounting expects the shortfall to be eliminated by end-2026 (or extended to 2027 if GPU supply exceeds expectations) and warns of a double-ordering unwind; TrendForce and the supply chain believe tightness will persist through 2027–2028 — this is the biggest uncertainty for 2027 industry growth and pricing. Competitive structure: US and Japanese companies hold over 80% share of high-end EML/CW (company inquiry response caliber); the domestic camp includes Yuanjie (CW mainstay + 200G EML in qualification), Changguang Huaxin (100G EML in volume production + 200G in sampling), Wuhan MX, and CAS Photonics still ramping. Entry barriers: 6-inch InP production lines require investment of over RMB 1 billion; qualification cycles of 2–12 months with winner-take-all dynamics; equipment and substrates depend on imports. Substitution threats: silicon photonics (CW replacing some EML; 1.6T silicon photonics penetration already past half), CPO (form factor change but doubled laser consumption per system) — a double-edged sword for the company (CW + the Xingyue product line are the upside; 200G EML ramping into oversupply is the risk). The high-power side is fragmented: Raycus/Maxphotonics with vertical integration and in-house R&D, plus independent chip makers like Dugen Corechip, with price war risk deferred until supply releases in 2027.
5. Cycles and Regulation: AI optical chips are in the mid-stage of an upcycle (30% shortfall, price hikes, capacity expansion wave); leading indicators = cloud provider capex guidance, 800G/1.6T shipments, InP substrate and refined indium prices, EML lead times, GPU supply; high-power is in a weak recovery within maturity. Three regulatory threads: ① The US FCC is drafting a ban on imports of new-model Chinese datacenter optical modules (Reuters, August 2026; officials target announcement within 2026; Citi notes supply bottlenecks in enforcement, with possible revision or shelving) — a tail risk and a two-way variable; ② China added indium phosphide to export licensing in February 2025 and in 2026 capped annual indium exports at 30% of production (China holds about 75% of global indium reserves) — strengthening resource supply security for domestic chip makers; ③ Continued investment in import substitution and the Big Fund — the policy backdrop is broadly favorable for domestic optical chips.
6. Peer Benchmarking: See the peer benchmarking table in Section X, "Valuation and Odds." Scale ranking: Yuanjie H1 revenue of RMB 925 million > Shijia RMB 1.495 billion (mostly passive components) > Changguang Huaxin RMB 391 million; profitability realization: Yuanjie H1 net profit of RMB 607 million vs. Changguang Huaxin RMB 30 million (ranked 12th in the industry per Sina Securities) — a full order of magnitude gap in profitability within the same track, serving as both precedent and ceiling for the "gross margin recovery" narrative.
7. Company Positioning in the Industry: "One stable, one elastic" — first tier in domestic high-power (the company claims 13.41% domestic share and 3.88% global, 2020 prospectus caliber; third-party EET-China cited Dugen Corechip's 2024 China laser chip share including devices at 37.4%, ranking first — the two calibers differ in statistical scope (pure chips vs. chips plus devices), listed side by side for reference), with share trend flat; a high-elasticity challenger starting from zero in optical communication (share estimated at 1% → 3–5%, rising), but trading margin for share, with profit quality far below Yuanjie. Overall positioning: a niche leader in high power + a high-elasticity challenger in optical communication; its scarcity is real (the only full-stack IDM optical chip maker in China), but whether the scarcity premium justifies 75x PS is another matter.
A generic financial framework tends to miss the three decisive factors of IDM optical chips; they are listed separately here:
Overall Assessment: Cautiously bearish: the current price is about 44% above the baseline fair median and about 54% above the probability-weighted fair value, with multiple triggerable convergence points within the next 12 months); confidence level 0.60, time horizon 12 months. The judgment does not depend on "the market being 100% wrong" — the bull case has a 20% probability of materializing and A-share scarcity premium has current evidence (Yuanjie at 139.7x PS), but by the odds calculation, the current price has already pulled forward the 2030 bull case, making expected returns significantly negative.
Strategy: Holders should use event-driven rallies (CIOE, Q4 volume production announcement) to reduce exposure; non-holders should not chase the price, but wait for one of two signals — price returning to the 175–215 yuan baseline range, or fundamental validation ("gross margin recovering to 15%+ in a single quarter and non-GAAP/non-recurring profit positive for two consecutive quarters / announcement-level major customer orders for 200G") before re-evaluating. The right way to go long on this stock is to wait for validation, not for the story.
Two-Way Risk Warnings: Downside — continued gross margin decline or another non-recurring loss in Q3 results (consensus downward revision), FCC ban materializing, EML supply release in 2027 triggering a price war, a new round of share reduction plans by Huafeng/Yinglei, fair value giveback of the photonics fund; Upside (i.e., the reverse risk to this judgment) — 200G EML major customer orders landing combined with a gross margin jump, re-rating toward the upper end of the bull-case range at 330 yuan, a replay of the Yuanjie-style "gross margin doubling in four quarters" path.
Tracking Calendar and Trigger Conditions (systematic monitoring list established in parallel):
Invalidation and Re-evaluation Conditions (selected): Share price falls below 175 yuan (entering the baseline fair range; overvaluation thesis largely confirmed; re-evaluate entry); share price rises above 330 yuan (breaking the bull-case upper bound; scenario distribution invalidated; re-examine); announcement-level bulk orders for 200G EML from major customers; optical communication single-quarter gross margin recovering above 25%; full-year 2026 non-recurring profit turning positive; FCC formally adding optical modules to the control list; any hyperscaler cutting 2027 capex; Huafeng/Yinglei/Hubble disclosing a new round of share reduction plans or confirming "no further reduction upon expiry."
