1. Executive Summary

The most decision-relevant fact about Sanan Optoelectronics is that core-business profitability has yet to recover: revenue in 1H 2026 was RMB 6.468 billion, down 28.04% year on year; net profit attributable to the parent was a loss of RMB 98 million, while net profit attributable to the parent excluding non-recurring items was a loss of RMB 504 million. Excluding the impact of changes in revenue-recognition methods for precious-metal scrap, revenue increased 8.97% year on year, but operating costs increased 13.22%. Low utilization, depreciation and amortization, and product-mix issues in filters, silicon carbide and other businesses continued to weigh on profit. In 2025, net profit attributable to the parent was also a loss of RMB 353 million, indicating continued pressure on profitability.

The company’s businesses cover LED epitaxial wafers and chips, LED application products, gallium arsenide RF, gallium nitride, silicon-carbide power devices, optical-communications chips and materials sales, giving it a relatively complete compound-semiconductor industry-chain footprint. In 2025, revenue from LED epitaxial wafers and chips was approximately RMB 5.862 billion, with gross margin rising to 22.43%. Gross margin for integrated-circuit products improved from -0.54% in 2024 to 5.64%, but gross margin for LED application products declined to 4.73%, reflecting the impact of pricing competition in mature businesses, higher raw-material prices and expansion of low-margin application businesses.

The company retains advantages in scale, industry-chain completeness and customer coverage. Mini/Micro LED, automotive LEDs, silicon carbide, RF and optical communications provide medium- to long-term growth opportunities, but these businesses are generally still in customer validation, capacity ramp-up or utilization-improvement phases. In 1H 2026, the company recognized RMB 333 million in various credit and asset impairment losses, including RMB 329 million in inventory write-downs. The gap of approximately RMB 406 million between net profit attributable to the parent and net profit excluding non-recurring items also indicates that reported profit is relatively sensitive to non-recurring items.

As of September 11, 2026, the share price was RMB 12.43, near the lower end of its 52-week range, with a price-to-book ratio of approximately 1.8x. However, because the company reported losses over the latest four quarters, the conventional P/E ratio is not meaningful. Technically, the share price was below the main short- and medium-term moving averages, MACD was below the zero axis, and major funds had recorded recent consecutive net outflows. Following the volume-backed limit-up on September 3, no sustained breakout occurred; the stock currently appears closer to low-volume, weak consolidation after a period of high volatility.

2. Company Overview

2.1 Basic Information

2.2 Core Businesses and Product Footprint

• LED epitaxial wafers and chips: Main products include red/yellow- and blue/green-light LED epitaxial wafers and chips, used in general lighting, displays, Mini LED backlighting, Micro LED displays, automotive lighting, plant lighting, ultraviolet, infrared and laser applications. Revenue was approximately RMB 6.037 billion in 2024, accounting for approximately 37.5% of that year’s revenue, with a gross margin of 20.56%; revenue was approximately RMB 5.862 billion in 2025, with gross margin rising to 22.43%.
• LED application products: Mainly includes specialty packaging, LED lamp beads, modules and automotive lamps. Revenue was approximately RMB 2.604 billion in 2024, with a gross margin of 10.10%; revenue was approximately RMB 3.230 billion in 2025, while gross margin fell to 4.73%, mainly due to lower product prices, higher raw-material prices and expansion of low-margin application-product businesses.
• Integrated-circuit products: Includes gallium-arsenide RF chips and foundry services, gallium-nitride RF products, RF filters, silicon-carbide power devices, silicon-based gallium-nitride power devices, optical-communications chips and related epitaxy, chips and foundry services. Downstream applications cover smartphone RF front ends, communications base stations, new-energy vehicles, charging stations, photovoltaic and energy-storage systems, AI servers, data centers, industrial power supplies, optical communications and automotive LiDAR. Revenue was approximately RMB 2.857 billion in 2024, with a gross margin of -0.54%; revenue was approximately RMB 2.916 billion in 2025, with gross margin improving to 5.64%.
• Materials and scrap sales: Revenue was approximately RMB 4.476 billion in 2024, with a gross margin of 8.60%; in 2025, the segment accounted for approximately 30.04% of revenue. The business includes the recovery and sale of materials and precious-metal scrap generated during production. Its relatively large revenue scale should not be equated directly with revenue from core high-technology semiconductor products.
• Industry-chain extension: The company covers substrates, epitaxy, chip manufacturing, power devices, RF devices, optical-communications chips, LED packaging and applications, while also developing silicon carbide, silicon-based gallium nitride, Mini/Micro LED and optical-technology businesses.

2.3 Position in the Upstream and Downstream Chain and Cost-Profit Structure

Sanan Optoelectronics occupies the core midstream manufacturing position in the compound-semiconductor industry chain, extending upstream into substrate materials and downstream into packaging, devices and applications. LED epitaxial wafers and chips are the most mature and largest business. Silicon carbide, gallium nitride, gallium-arsenide RF and indium-phosphide optical-chip businesses remain in capacity-expansion, customer-validation or ramp-up phases.

• Major procurement inputs include sapphire substrates; gallium-arsenide, silicon-carbide and indium-phosphide compound-semiconductor substrates; gallium, gold, platinum, silver, copper and other metals or precious-metal materials; and MOCVD, lithography, etching, cleaning and thin-film-deposition equipment.
• Other key inputs include high-purity specialty gases, chemicals, target materials, photoresists and packaging materials. LED-chip production also involves materials such as metal-organic sources.
• The company is developing internal supporting capabilities in certain substrate and epitaxy processes and has scale-based procurement capabilities, but still needs to purchase substantial quantities of equipment, chemical materials and metal consumables.
• As of December 31, 2024, purchases from the five largest suppliers totaled approximately RMB 6.339 billion, accounting for 46.63% of total purchases. This figure is from the third-party Tonghuashun financial database and was not cross-checked item by item against the complete supplier disclosures in the annual report; the original annual-report table should prevail.
• Traditional LED lighting and mid- to low-end display products are highly homogenized. The company lacks absolute pricing power over downstream selling prices and cannot fully pass material, depreciation and labor costs on to customers. Rising prices of gallium, gold, platinum, silver, copper and other materials, particularly gold and silver, directly compress gross margins in relevant businesses.
• Downstream customers and applications include LED packaging plants, display manufacturers, television and display-module companies, lighting companies, automotive-parts and lamp manufacturers, handset and communications-equipment makers, photovoltaic, energy-storage and charging-station manufacturers, new-energy vehicle companies, optical-communications equipment makers, and AI-server and data-center supply-chain companies.
• As of December 31, 2024, sales to the five largest customers totaled approximately RMB 7.560 billion, accounting for 42.12% of revenue. This figure is from the third-party Tonghuashun financial database and was not cross-checked item by item against the complete customer disclosures in the annual report during this review; the original annual-report table should prevail.
• Downstream traditional LED chips face intense price competition. Packaging, lighting and display customers are sensitive to price, delivery and yield, with bargaining power concentrated more with large end brands, packaging companies and system manufacturers.
• Customer-certification cycles for Mini/Micro LED, automotive LEDs, silicon-carbide power devices, RF and optical-communications chips are relatively long, while technical, reliability and customer-introduction barriers are high. After entering a leading customer’s supply chain, customer stickiness is generally higher than for general-lighting chips, but early-stage validation and capacity ramp-up create high fixed costs.
• During 2023–2025, traditional LED chips, packaging and general-lighting businesses experienced concentrated capacity releases, insufficient demand growth and price wars, leaving the traditional businesses with limited pricing power.
• As of December 31, 2024, the gross accounts-receivable balance on a consolidated basis was approximately RMB 3.756 billion, with bad-debt provisions of approximately RMB 169 million and a net carrying value of approximately RMB 3.586 billion, equal to 16.52% of current assets. Based on 2024 revenue of approximately RMB 16.106 billion, net accounts receivable represented approximately 22.3% of revenue. This indicates that the company does not rely entirely on immediate cash settlement; downstream customers have certain payment periods, creating working-capital usage. This review could not reliably extract 2024 receivables turnover days, customer payment periods by business, contract liabilities or the customer-by-customer proportions of the five largest customers from the company’s original annual-report text, so no further inference is made.
• The main available customer- and supplier-concentration data are third-party database figures for 2024: the five largest customers accounted for 42.12% of sales and the five largest suppliers accounted for 46.63% of purchases. The data source is limited and was not cross-checked item by item against complete annual-report disclosures; the latest annual report should prevail. The company’s market-share data mainly comes from its responses to regulatory inquiries regarding the 2025 annual report and has not been fully independently verified by a third party; it should be viewed as company-disclosed data.

The company is positioned at the core midstream manufacturing stage of the compound-semiconductor industry chain. Traditional LED general-lighting chips are midstream products with large scale but limited pricing power; LED packaging and modules are closer to downstream applications and currently have low gross margins. Silicon-carbide substrates, epitaxy and power devices, as well as Mini/Micro LED, automotive LEDs and optical-communications chips, are extending toward upstream materials and higher-value-added device segments. Key drivers of further profit improvement include a higher proportion of high-value-added products, better utilization of silicon-carbide and RF lines, customer validation and volume ramp-up, material-cost control and depreciation dilution through scale.

3. Financial Data and Valuation Analysis

3.1 Recent Operating Performance

The 1H 2026 report was disclosed on August 26, 2026 and was unaudited. Net profit attributable to the parent excluding non-recurring items was a loss of RMB 504 million in 1H 2026, down 402.47% YoY; FY 2025 net profit excluding non-recurring items was a loss of RMB 828 million, deteriorating a further 61.94%. Basic EPS was -RMB 0.02 in 1H 2026 and -RMB 0.07 for FY 2025.

Revenue declined year on year in 1H 2026, partly because precious-metal scrap recycling was changed from external sales to physical exchange effective November 1, 2025 and January 1, 2026, respectively; the relevant businesses therefore no longer recognized revenue or operating costs. Excluding the impact of precious-metal scrap, revenue increased 8.97% year on year in 1H 2026, but operating costs rose 13.22%, leaving core-business profitability under pressure. The LED business remained profitable overall, but filters, silicon carbide and other businesses continued to weigh on profit because of low utilization, incomplete product-mix improvement, depreciation and fixed-amortization pressure. The approximately RMB 406 million gap between net profit attributable to the parent and net profit excluding non-recurring items was mainly related to asset-disposal gains, government grants and other non-recurring items. Reported net profit therefore does not fully represent core profitability.

3.2 Earnings Forecast

The above 2026–2027 forecasts come from the single overseas data platform MarketScreener and could not be cross-checked against Tonghuashun’s publicly available earnings-forecast pages; they should not be regarded as a multi-institution consensus. Tonghuashun shows no valid institutional earnings forecast for 2026 and no usable forecast for 2027. The company’s 1H 2026 earnings preannouncement projected a net loss attributable to the parent of RMB 90 million–135 million and a loss excluding non-recurring items of RMB 490 million–550 million; final first-half results were within the guidance range.

3.3 Valuation and Institutional Ratings

At the September 11, 2026 close, the share price was approximately RMB 12.43, total shares outstanding were approximately 4.989 billion and market capitalization was approximately RMB 62.0 billion. Net assets attributable to the parent in the 1H 2026 report were RMB 34.690 billion, or approximately RMB 6.95 per share, implying a static P/B ratio of approximately 1.79x. Because the latest four quarters remained loss-making overall, the TTM P/E was negative and the conventional P/E was not meaningful. Based on the MarketScreener forecast, 2026 forecast EPS of approximately RMB 0.2892 implies a forward P/E of approximately 43.0x; 2027 forecast EPS of approximately RMB 0.35 implies a forward P/E of approximately 35.5x. Based on the current market capitalization of approximately RMB 62.0 billion, if full-year 2026 net profit reaches RMB 1.0–1.5 billion, the corresponding 2026 P/E would be approximately 41–62x. Overall, the company’s P/B is approximately 1.8x, but forward P/E remains high, indicating that the market has partly priced in an earnings turnaround. Valuation depends primarily on whether the company can turn profitable for full-year 2026 and whether profitability improves in silicon carbide, filters and optical chips. Ratings are generally bullish, but target prices and earnings forecasts differ materially in timing, source and definition. Key items to monitor include LED product prices and gross margin, silicon-carbide utilization at Hunan Sanan, narrowing losses in the filter business, optical-chip revenue and profitability, changes in inventory write-downs, and improvement in 3Q 2026 profit excluding non-recurring items.

Recent matters related to shareholder interests mainly included the chairman’s purchase on behalf of the general manager, withdrawal of the bankruptcy-reorganization application by the controlling shareholder’s creditor, and continued waiting-list freezes on the controlling shareholder’s shares. The asset-impairment announcement disclosed on August 26 concerned interim financial matters and was not an M&A or buyback matter.

5. Share-Price Trend and Technical Analysis

5.1 Price Overview

5.2 Technical Indicators

As of September 11, 2026, Sanan Optoelectronics closed at RMB 12.43, near the lower end of its 52-week range. The volume-backed September 3 limit-up failed to produce a sustained breakout, the share price retreated on heavy turnover on September 4 and weakened thereafter. Moving averages, MACD and RSI all indicated weak short- to medium-term technical conditions. The price was near the estimated lower Bollinger Band, but no clear reversal signal had formed. Recent five-day turnover and trading value had fallen sharply from the exceptional volume on September 3–4, while major funds recorded consecutive net outflows and the margin balance declined. Overall, the stock appeared closer to low-volume, weak consolidation after high volatility. Shareholder-concentration data as of June 30, 2026 showed that the ten largest shareholders held approximately 51.3% in aggregate, but the increase in shareholder count and decline in average holdings indicated that the statistically measured ownership base was becoming more dispersed. The data are quarterly and lagged, and cannot directly represent the latest ownership structure as of September 11, 2026.

5.3 Short-Term Outlook (Next Week, Scenario Analysis for Reference Only)

⚠️ Risk warning: The following is a subjective scenario analysis based on data as of the September 11, 2026 close. It does not constitute investment advice or a definitive forecast of future share prices.

① Key Technical Levels

② Scenarios for the Next Week (Subjective Weights, Not Statistical Probabilities)

• Range-bound consolidation (relatively higher subjective heuristic weight, approximately 60%; not a statistical probability): Price range approximately RMB 12.10–12.90. Conditions include holding RMB 12.10–12.30, turnover remaining near the recent norm of approximately RMB 900 million–1.4 billion, a clear narrowing of major-fund outflows, and a rally toward RMB 12.70–12.90 that retreats without a high-volume breakout or breakdown. Under this scenario, weak repair may continue, but there would still be insufficient confirmation of a trend reversal.
• Weak downside move (medium subjective heuristic weight; not a statistical probability): Price range approximately RMB 11.00–12.20. Conditions include a decisive closing break below support near RMB 12.10, daily value traded expanding again above RMB 1.5 billion while major funds continue to flow out, simultaneous weakness in semiconductor and optoelectronics sectors, or further margin-balance declines and weaker market absorption. If RMB 12.10 breaks on heavy volume, short-term support may be sought around RMB 11.50–11.80; further weakness would bring RMB 10.80–11.20 into focus.
• Strengthening rebound (low to medium subjective heuristic weight; not a statistical probability): Price range approximately RMB 12.80–13.50. Conditions include reclaiming RMB 12.90 with consecutive closing confirmation, value traded recovering to at least RMB 1.5 billion and exceeding the approximately RMB 1.254 billion five-day average, major funds shifting from consecutive net outflows to consecutive net inflows, and simultaneous gains in semiconductor or optoelectronics sectors. A further high-volume break above RMB 13.30 could open room for recovery toward the RMB 13.80–13.90 resistance zone; without volume and major-fund support, a one-day rebound is more likely to be an oversold recovery.

③ Funding and Liquidity Background

From September 7–11, 2026, value traded was approximately RMB 911 million–1.682 billion and turnover approximately 1.44%–2.59%; the five-day average value traded was approximately RMB 1.254 billion and average turnover was approximately 1.96%. Value traded exceeded RMB 3.4 billion on September 3–4 before falling significantly, indicating reduced short-term trading interest and a low-volume digestion phase. Shareholder data as of June 30, 2026 showed 580,535 shareholders, an increase of 170,702, or 41.65% quarter on quarter, from March 31, 2026, with approximately 8,594 shares per shareholder. The ten largest shareholders held approximately 51.3% in aggregate. They included Xiamen Sanan Electronics Co., Ltd. (22.65%), Changsha XianDao Gaoxin Investment Partnership (5.74%), the company’s repurchase-designated securities account (5.67%), Fujian Sanan Group Co., Ltd. (3.66%), Hong Kong Securities Clearing Company Limited (2.25%), Gree Electric Appliances, Inc. of Zhuhai (2.07%), Changsha Fuxin Industrial Investment Partnership (1.94%), the Third Employee Stock Ownership Plan (1.52%), Xiamen ITG Innovation Investment Co., Ltd. (1.26%) and UBS AG (0.55%). The list includes controlling shareholders, a repurchase account, an employee stock-ownership plan and industrial investors, and cannot simply be equated with concentrated holdings by public funds or long-term institutions. Although Hong Kong Securities Clearing, UBS and semiconductor ETFs represent institutional or channel capital, the overall structure remains dominated by controlling shareholders, industrial capital, the company’s repurchase account and the employee stock-ownership plan. The data are approximately two and a half months old, and the actual ownership structure may have changed. Given consecutive major-fund outflows, a falling margin balance and a share price below short- and medium-term moving averages, the current market structure is closer to low-volume, weak consolidation after high volatility. In actual trading, changes in volume and the resulting strength of demand and ownership transfer should be monitored.

A quantifiable volume-confirmation signal would be two consecutive days with value traded above RMB 1.5 billion, simultaneous conversion of major funds to net inflows, and a closing price above RMB 12.90–13.00. This could be viewed as an observation signal of improved short-term fund absorption. If volume expands while major funds continue to post large net outflows, the risks of ownership transfer or fund distribution should remain in focus.

④ Points to Monitor (Observation Framework Only, Not Trading Instructions)

• Observe whether the RMB 12.10–12.30 support zone sees low-volume stabilization or a high-volume breakdown.
• Observe whether RMB 12.70–12.90 can be reclaimed and held; failure would leave any rebound vulnerable to short-term moving-average resistance.
• Observe volume changes in the dense medium-term moving-average resistance zone at RMB 13.00–13.30, and whether a break above RMB 13.30 is accompanied by expanding volume.
• Observe whether value traded exceeds RMB 1.5 billion for two consecutive days, and assess the effectiveness of rebound absorption together with the direction of major funds. These are observation guidelines only, not trading instructions.

The above scenario analysis is based on the September 11, 2026 closing data and historical-price and technical-indicator estimates. Short-term prices will also be affected by news, liquidity, the broader market and other factors. Technical indicators are inherently lagging and limited, and this analysis does not guarantee future performance or constitute a buy or sell recommendation. Investors should independently assess the latest market information and bear investment risks themselves.

6. Industry Landscape and Competitor Analysis

6.1 Industry Status

Sanan Optoelectronics spans LED chips, LED packaging and applications, silicon carbide, gallium nitride, gallium-arsenide RF and optical communications. The LED-chip industry combines scale, capital intensity and price competition. Silicon carbide and other third-generation semiconductors remain in the stages of domestic substitution, customer validation and capacity ramp-up. RF front ends and optical-communications chips have high technical barriers, but overseas companies still retain an advantage. Because the company’s business scope is broad, no single comparable company fully overlaps with it; comparisons should therefore be made by business segment.

6.2 Competitive Landscape

• General-lighting and mid- to low-end display chips have relatively ample supply and high product homogenization, resulting in intense price competition. MOCVD equipment, plants and automated production lines require substantial investment, and utilization materially affects unit costs and gross margins.
• High-end markets such as Mini/Micro LED, automotive LEDs and plant lighting have higher technical and customer-certification barriers. Industry profit is trending from traditional white-lighting chips toward high-end displays, automotive and specialty applications.
• The silicon-carbide chain includes powder and crystal growth, substrates, epitaxy, chips and modules, as well as applications in new-energy vehicles, photovoltaic and energy storage, and industrial power supplies. Technology, equipment, yield, material costs and customer-certification cycles are the key competitive factors.
• Sanan Optoelectronics is active in silicon-carbide substrates, epitaxy and chip processing, giving it an industry-chain-completeness advantage. However, some silicon-carbide MOS lines remain in low-utilization or validation phases and have not yet achieved stable profitability.
• The RF front-end and optical-communications chip markets face competition from overseas IDM manufacturers, RF front-end design companies and specialized domestic RF companies. Sanan has capabilities in gallium-arsenide RF manufacturing, gallium-nitride RF, filters, epitaxy and chip foundry services.
• Sanan Optoelectronics has disclosed a global LED-chip market share of approximately 32%, a domestic share of approximately 32.8%–35%, a domestic Mini LED share of approximately 38% and a domestic Micro LED share of approximately 45%. These figures mainly come from the company’s response to the regulatory inquiry and have not been fully cross-checked by an independent third party.

6.3 Major Competitors

Compared with pure LED-chip companies, Sanan Optoelectronics has a relatively complete compound-semiconductor platform spanning substrates, epitaxy, chips, devices, packaging and applications. Compared with upstream-material companies such as SICC, Sanan is more diversified and extends into epitaxy, chips and devices. Compared with power-semiconductor companies such as China Resources Microelectronics and Silan Microelectronics, Sanan’s LED business provides a more important mature-business base. Its competitiveness is reflected mainly in scale, industry-chain completeness, patents and customer coverage, but traditional LED businesses have limited pricing power, while new businesses continue to face customer validation, utilization, product-price and fixed-cost-amortization pressures.

7. Risk Factors

• Risk of continued deterioration in core profitability: In 1H 2026, net profit attributable to the parent was a loss of RMB 98 million and profit excluding non-recurring items was a loss of RMB 504 million. Excluding precious-metal scrap, revenue still increased 8.97% YoY, but operating costs rose 13.22%. If costs continue to grow faster than revenue, recovery in core profitability may be delayed further.
• Risk of insufficient utilization in new businesses: Filters, silicon carbide and other businesses remain affected by low utilization, incomplete product-mix improvement, depreciation and fixed-amortization pressure. If customer validation, order ramp-up or production-line ramp-up falls short of expectations, these businesses may continue to drag on profit.
• Risk of falling LED prices and gross margins: LED application-product revenue rose to RMB 3.230 billion in 2025, but gross margin fell to 4.73% due to lower selling prices, higher raw-material prices and expansion of low-margin application products. Continued price competition in traditional lighting and display markets means revenue growth may not translate into profit growth.
• Inventory and asset-impairment risk: The company recognized RMB 333 million in credit and asset impairment losses in 1H 2026, including RMB 329 million in inventory write-downs. If prices, demand and utilization for LED, filters or silicon-carbide products remain under pressure, further inventory impairments may occur.
• Risk related to disposal of controlling-shareholder shares and control stability: As of September 3, 2026, Sanan Electronics and indirect controlling shareholder Sanan Group together held 26.30%, and all relevant shares had been judicially frozen. A further 30 million Sanan Electronics shares were placed under a waiting-list freeze. If debt, pledge and freeze issues are not properly resolved, the stability of company control could be affected.
• Corporate-governance uncertainty: As of September 4, 2026, actual controller Lin Xiucheng and Vice Chairman and General Manager Lin Kechuang remained under detention. Although the company stated that other directors and senior executives were performing their duties normally, these matters may create uncertainty for governance arrangements, operating decisions and market expectations.
• Revenue structure and earnings-quality risk: Materials and scrap sales were approximately RMB 5.826 billion in 2025 and represented a relatively large proportion of revenue. Precious-metal scrap activities were changed to physical exchange effective November 1, 2025 and January 1, 2026, and no longer recognize revenue or operating costs. Year-on-year revenue changes and financial indicators across periods are therefore significantly affected by accounting definitions; core semiconductor demand cannot be assessed simply from revenue growth.
• Valuation and share-price volatility risk: As of September 11, 2026, the share price was approximately RMB 12.43 and P/B approximately 1.8x, but the company remained loss-making and dynamic P/E had little practical meaning. If expectations for an earnings turnaround decline, the share price could be affected by valuation re-rating. Technically, the share price was below key moving averages; a high-volume break below RMB 12.10–12.30 could indicate continued weakness.

8. Conclusion and Outlook

Sanan Optoelectronics’ growth thesis is based on using its mature LED businesses as a foundation while increasing the proportion of high-value-added products through Mini/Micro LED, automotive LEDs, silicon-carbide power devices, RF and optical-communications chips. If utilization improves in silicon-carbide and filter lines, customer validation and volume ramp-up proceed smoothly, and gross margin for LED epitaxial wafers and chips remains on an improving trend, profitability could gradually recover. Market data for 2026–2027 point to an earnings turnaround, but the forecast comes from a single overseas platform and has not been cross-checked by multiple institutions.

The key issue to verify now is the quality of core earnings rather than revenue scale. This includes changes in revenue and gross margin after excluding materials and scrap sales, narrowing losses in filters and silicon carbide, changes in inventory write-downs, optical-chip revenue and profitability, and whether profit excluding non-recurring items improves in 2H 2026. The company remained loss-making excluding non-recurring items in 1H 2026, indicating that the earnings turnaround has not yet been sufficiently confirmed by financial data.

In addition, all shares held by the controlling shareholder and indirect controlling shareholder have been judicially frozen, with waiting-list freezes and control-stability risks. The actual controller and Vice Chairman and General Manager also remain under detention. From a share-price perspective, RMB 12.10–12.30 is the near-term support zone, while RMB 12.70–12.90 and RMB 13.00–13.30 are moving-average resistance zones. Technical trends should nevertheless be assessed together with operating results, governance matters and liquidity conditions.
