Executive Summary

Longi Green Energy Technology Co., Ltd. ("Longi" or the "Company"), the global leader in monocrystalline silicon wafers and solar modules, has released its financial results for the third quarter of 2025. The report highlights a critical inflection point in the Company’s strategic transition from traditional PERC technology to its proprietary Back Contact (BC) technology platform. While the broader photovoltaic (PV) industry continues to grapple with severe overcapacity and intense price competition, Longi demonstrates resilience through operational efficiency improvements, rigorous cost control, and the accelerating commercialization of its next-generation HPBC 2.0 products.

Key Performance Highlights for 3Q25:
* Revenue & Profitability: In 3Q25, Longi reported revenue of CNY 18.1 billion, representing a sequential decline of 5.5% and a year-over-year (YoY) decline of 9.8%. However, the net loss attributable to shareholders narrowed significantly to CNY 830 million, marking a 33.9% YoY improvement and a 26.4% sequential improvement. The gross margin improved sequentially by 3.3 percentage points (pct) to 4.9%, indicating that the worst of the pricing pressure may be stabilizing for premium products.
* BC Technology Ramp-up: The most significant operational development is the rapid scaling of BC module shipments. In 3Q25, BC module shipments reached approximately 6 GW, a substantial ~50% sequential increase. For the first nine months of 2025 (9M25), total BC module sales amounted to 14.48 GW out of a total battery/module shipment volume of 63.43 GW. This confirms that BC technology is transitioning from a niche premium product to a core revenue driver.
* Financial Health & Cash Flow: Despite reporting net losses, Longi’s cash flow generation remains robust. Operating cash flow for 3Q25 surged to CNY 2.3 billion, a 217.9% YoY increase and an 82.3% sequential increase. The Company maintains a strong balance sheet with ample liquidity, allowing it to sustain capital expenditure for technological upgrades while navigating the industry downturn.
* Capacity Expansion: By the end of 3Q25, Longi’s self-owned BC 2.0 production capacity reached 35 GW. The Company projects that through technical upgrades, its HPBC 2.0 battery capacity will reach 50 GW by the end of 2025, positioning it as the largest producer of high-efficiency BC cells globally.

Investment Thesis:
We maintain our "Buy" rating on Longi Green Energy. The investment case is underpinned by three core pillars:
1. Technological Moat: Longi’s decisive bet on BC technology is paying off. As the industry shifts away from homogeneous PERC/TOPCon competition, BC’s higher efficiency and aesthetic advantages allow Longi to command a premium and protect margins better than peers stuck in legacy technologies.
2. Operational Turnaround: The consistent narrowing of losses quarter-over-quarter suggests that management’s strategy of "quality over quantity" and aggressive cost reduction is working. The company is successfully shedding low-margin inventory and optimizing its product mix.
3. Valuation Appeal: Trading at a Price-to-Book (P/B) ratio of ~2.8x and with expectations of a return to profitability in 2026, the current valuation discounts the severe cyclical trough. As the supply-side clearance accelerates and demand for high-efficiency modules grows, Longi is well-positioned for a earnings rebound in 2026-2027.

While near-term headwinds persist due to industry-wide oversupply, Longi’s superior balance sheet and technological leadership provide a defensive shield and an offensive engine for the next cycle. We adjust our 2027 earnings forecast slightly downward to reflect prolonged competition but reaffirm the long-term growth trajectory.

Key Takeaways

1. Financial Performance Analysis: The Path to Stabilization

The financial results for the third quarter of 2025 reveal a company in the midst of a difficult but necessary restructuring phase. The top-line revenue contraction is a deliberate outcome of shifting sales mix towards higher-value BC products and reducing shipments of lower-margin legacy products.

1.1 Revenue and Profit Trends

• 9M25 Overview: For the first nine months of 2025, Longi generated total revenue of CNY 50.91 billion, a YoY decline of 13.1%. The net loss attributable to shareholders was CNY 3.4 billion, which represents a 47.5% YoY improvement in loss magnitude. The non-GAAP net loss (deducting non-recurring items) was CNY 4.45 billion, improving by 31.4% YoY.
• 3Q25 Specifics:
  • Revenue: CNY 18.1 billion. The sequential drop of 5.5% is attributed to seasonal factors and the ongoing optimization of shipment structures.
  • Net Loss: CNY 830 million. This is a crucial metric. While still negative, the trajectory is clearly positive. The YoY improvement of 33.9% indicates that the Company is faring better than the general market sentiment might suggest, especially given the drastic drop in average selling prices (ASPs) across the PV sector.
  • Margins: The gross margin for 3Q25 stood at 4.9%. Although this is down 3.7 pct YoY (reflecting the overall industry price war), it is up 3.3 pct sequentially. This sequential improvement is a vital signal. It suggests that the impact of inventory write-downs is diminishing and that the higher ASPs of BC modules are beginning to offset the lower ASPs of standard modules. The net margin attributable to shareholders was -4.6%, improving by 1.7 pct YoY and 1.3 pct sequentially.

Note: Data derived from report estimates and historical comparisons.

1.2 Expense Management and Operational Efficiency

Longi has demonstrated exceptional discipline in controlling operating expenses, a key factor in mitigating losses during a downturn.
* Period Expenses (9M25): Total period expenses amounted to CNY 4.14 billion, a 24.7% YoY decrease. The expense ratio dropped to 8.1%, down 1.3 pct YoY.
* 3Q25 Expenses: Period expenses were CNY 1.62 billion. While this represents a sequential increase of 35.8% (likely due to timing of R&D spending and administrative accruals), it is still a 12.8% YoY decrease. The expense ratio for the quarter was 9.0%, down 0.3 pct YoY but up 2.7 pct sequentially. The sequential rise warrants monitoring, but the YoY trend confirms structural cost reductions.
* R&D Focus: Despite cost-cutting, Longi continues to invest in R&D, particularly for BC technology iterations. This balanced approach ensures that short-term savings do not compromise long-term technological leadership.

1.3 Cash Flow and Capital Structure

One of Longi’s strongest assets is its financial fortitude. In an industry where many competitors are facing liquidity crises, Longi’s cash flow profile remains healthy.
* Operating Cash Flow (OCF):
* 9M25: OCF was CNY 1.82 billion, a remarkable 121.7% YoY increase. This indicates that the Company is effectively collecting receivables and managing working capital despite lower sales volumes.
* 3Q25: OCF surged to CNY 2.3 billion, up 217.9% YoY and 82.3% sequentially. This strong cash generation provides the flexibility to fund the BC capacity expansion without excessive reliance on external debt.
* Capital Expenditure (CapEx):
* 9M25: CapEx totaled CNY 4.68 billion, a slight 2.3% YoY decrease.
* 3Q25: CapEx was CNY 470 million, a sharp 66.7% YoY decrease and 39.2% sequential decrease. This reduction reflects the completion of major construction phases for existing BC lines and a more cautious approach to new greenfield projects amidst uncertainty. The focus has shifted from capacity quantity to capacity quality (upgrading existing lines to BC 2.0).
* Inventory Levels: Inventory at the end of 3Q25 stood at CNY 14.52 billion, an 8.5% increase from the beginning of the year. Given the revenue decline, this absolute increase suggests some accumulation, possibly of raw materials for the BC ramp-up or finished goods awaiting shipment. However, given the improved gross margins, the risk of significant future write-downs appears to be receding compared to previous quarters.

2. Operational Deep Dive: The BC Revolution

The core narrative for Longi in 2025 and beyond is the successful commercialization of its Back Contact (BC) technology. This section analyzes the shipment data, capacity expansion, and competitive implications of this strategic pivot.

2.1 Shipment Analysis: Quality Over Quantity

• Total Shipments (9M25):
  • Silicon Wafers (External Sales): 38.15 GW.
  • Cells & Modules: 63.43 GW.
• 3Q25 Shipment Estimates:
  • Silicon Wafers: Approximately 12-13 GW. The report notes that wafer profitability per watt improved sequentially. This is significant because the wafer segment has been the most loss-making part of the value chain due to massive oversupply. The improvement suggests that Longi is either reducing low-cost external sales or that internal transfer pricing adjustments are reflecting better value capture.
  • Cells & Modules: Approximately 22.58 GW.
  • BC Module Shipments: Approximately 6 GW in 3Q25 alone. This is the standout figure.
    • Sequential Growth: ~50% increase from 2Q25.
    • Penetration Rate: BC modules now represent roughly 26.5% of total module shipments in 3Q25 (6 GW / 22.58 GW). This is a rapid adoption curve.
    • Profitability: The report states that the loss per watt for BC modules remained flat sequentially. While still loss-making (likely due to initial ramp-up costs and depreciation), the fact that losses did not widen despite a 50% volume increase indicates strong operational learning curves and yield improvements. As volumes scale further into 2026, we anticipate BC modules will become the primary profit contributor, potentially turning profitable on a standalone basis sooner than expected.

2.2 Capacity Expansion: HPBC 2.0 Leadership

Longi is not just selling BC; it is building the infrastructure to dominate the BC market.
* Current Status (End of 3Q25): Self-owned BC 2.0 capacity reached 35 GW.
* Near-Term Target (End of 2025): The Company expects to reach 50 GW of HPBC 2.0 battery capacity through technical upgrades.
* Strategic Implication:
* Scale Advantage: By reaching 50 GW, Longi will achieve economies of scale that smaller BC players cannot match. This lowers the unit cost of production, narrowing the cost gap with TOPCon.
* Technology Iteration: The shift to "2.0" implies improvements in efficiency (likely exceeding 26.5% for modules) and reliability. HPBC (Hybrid Passivated Back Contact) combines the benefits of HJT (Heterojunction) and BC, offering higher open-circuit voltage and better temperature coefficients.
* Barrier to Entry: The capital intensity and technical complexity of BC manufacturing create a high barrier to entry. Longi’s early mover advantage and massive installed base of upgraded capacity solidify its moat.

2.3 Market Positioning and Pricing Power

The PV industry has suffered from commoditization, where products are differentiated only by price. BC technology disrupts this dynamic.
* Differentiation: BC modules offer superior aesthetics (no front grid lines) and higher efficiency. This makes them particularly attractive for distributed generation (residential and commercial rooftops) and high-end utility projects where land use efficiency is critical.
* Premium Pricing: While the report does not explicitly state the price premium, industry data suggests BC modules can command a premium of CNY 0.1-0.2/W over standard TOPCon modules. As BC shipments grow to 50%+ of Longi’s mix in 2026, this premium will significantly uplift the Company’s blended ASP and gross margin.
* Customer Acceptance: The rapid ramp in shipments (6 GW in Q3) indicates strong market acceptance. Longi’s brand reputation and global distribution network are effectively converting technological advantage into market share.

3. Industry Context and Competitive Landscape

To fully appreciate Longi’s performance, one must view it against the backdrop of the global PV industry in late 2025.

3.1 Industry Oversupply and Price War

The global PV supply chain remains in a state of severe oversupply. Prices for silicon wafers, cells, and modules have hovered near or below cash cost for much of 2024 and 2025.
* Impact on Peers: Many competitors, particularly those heavily invested in PERC or late-stage TOPCon, are reporting deeper losses and facing liquidity constraints. Some smaller players have exited the market or paused expansion.
* Longi’s Relative Performance: Longi’s ability to narrow losses while peers deteriorate highlights its operational superiority. The sequential margin improvement (Gross Margin +3.3 pct QoQ) is a rare positive signal in a sector where margins are generally compressing. This suggests Longi is gaining market share in the "high-quality" segment while exiting the "low-price" segment.

3.2 The Technology Shift: From TOPCon to BC

2023-2024 was the year of TOPCon expansion. 2025-2026 is shaping up to be the year of BC differentiation.
* TOPCon Saturation: TOPCon has become the new standard, leading to fierce competition and eroding margins. The technology ceiling for TOPCon is approaching, with limited room for further efficiency gains.
* BC as the Next Gen: BC technology offers a clearer path to >27% module efficiency. Longi’s commitment to BC positions it at the forefront of the next technology cycle. Investors should view Longi not just as a solar manufacturer, but as a technology platform company leading the transition to ultra-high-efficiency solar.

3.3 Policy and Demand Drivers

• Global Demand: Despite trade barriers (e.g., US tariffs, EU investigations), global solar demand remains robust, driven by energy security concerns and climate goals. Emerging markets (Middle East, Asia-Pacific) are showing strong growth.
• China’s Supply-Side Reform: The Chinese government has signaled intent to address overcapacity through stricter energy consumption standards and quality benchmarks. This policy environment favors large, efficient, and technologically advanced players like Longi, while squeezing out inefficient capacity.

Risks / Headwinds

While the outlook is improving, investors must remain cognizant of the significant risks facing Longi and the broader PV sector.

1. Intensifying Competition

• Risk: Other major manufacturers (e.g., Aiko Solar, JinkoSolar, Trina Solar) are also expanding BC or similar back-contact capacities. If the industry converges on BC too quickly, it could replicate the TOPCon oversupply scenario, leading to price erosion in the BC segment.
• Mitigation: Longi’s 50 GW capacity target and proprietary HPBC technology provide a first-mover advantage. However, margin compression in the BC segment remains a possibility if supply outpaces demand.

2. Policy and Trade Barriers

• Risk: Geopolitical tensions continue to pose a threat. The US Inflation Reduction Act (IRA) favors domestic manufacturing, limiting Longi’s direct access to the lucrative US market. The EU’s potential carbon border adjustment mechanism (CBAM) and anti-subsidy investigations could increase costs or restrict access to the European market.
• Mitigation: Longi has a diversified global footprint and is exploring local manufacturing partnerships. However, trade barriers remain a persistent headwind for Chinese PV exporters.

3. Technological Execution Risk

• Risk: Scaling BC production is technically challenging. Yield rates and production costs must improve rapidly to achieve profitability. Any delays in the ramp-up of the 50 GW capacity or issues with product reliability could damage customer confidence and delay the return to profitability.
• Mitigation: Longi has a strong R&D track record. The sequential improvement in BC shipments suggests execution is on track. However, any technical setbacks could materially impact financial projections.

4. Macroeconomic and Interest Rate Environment

• Risk: Solar projects are capital-intensive and sensitive to interest rates. High global interest rates can dampen project economics, slowing down installation rates. Additionally, currency fluctuations (CNY vs. USD/EUR) can impact export competitiveness and financial reporting.
• Mitigation: Longi’s strong balance sheet allows it to weather macroeconomic volatility better than leveraged peers.

5. Inventory Write-Downs

• Risk: Although inventory levels are manageable, further declines in silicon or polysilicon prices could necessitate additional write-downs, impacting future quarters’ profitability.
• Mitigation: The Company has already taken significant provisions in 2024 and early 2025. The risk is lower now but not eliminated.

Rating / Sector Outlook

Sector Outlook: Cautiously Optimistic for Leaders, Bearish for Laggards

The photovoltaic sector is undergoing a painful but necessary consolidation. We believe the industry bottom is in sight, characterized by:
1. Supply Clearance: Inefficient capacity is being retired or paused.
2. Technology Differentiation: Value is shifting from generic capacity to high-efficiency, differentiated products (BC, HJT).
3. Demand Resilience: Long-term global decarbonization trends remain intact.

For the sector, we maintain a Neutral rating, but with a strong preference for technology leaders with robust balance sheets. The era of "rising tide lifts all boats" is over; the next phase will be "survival of the fittest."

Company Rating: Buy (Maintained)

We reiterate our Buy rating for Longi Green Energy.

Rationale for Rating:
1. Turnaround Visibility: The consistent narrowing of losses in 2025 provides visible evidence of operational improvement. The projected return to net profit in 2026 is highly credible given the BC ramp-up.
2. Valuation Support: At a P/B of ~2.8x, the stock is trading below its historical averages for a market leader. Given the expectation of ROE recovery to ~5-9% in 2026-2027, the current valuation offers an attractive entry point for long-term investors.
3. Strategic Clarity: Longi’s unwavering commitment to BC technology distinguishes it from peers who are hedging their bets. This clarity reduces execution risk and enhances investor confidence in the long-term strategy.

Earnings Forecast Adjustments:
We maintain our earnings forecasts for 2025 and 2026 but adjust 2027 slightly downward to reflect a more conservative view on long-term margin sustainability amid potential competition.

Source: Soochow Securities Estimates. Note: P/E is not meaningful for loss-making years.

Key Changes:
* 2027 Net Profit: Adjusted down to CNY 6.005 billion (from previous CNY 7.27 billion). This reflects a more prudent assumption on long-term gross margins as BC technology becomes more widespread and potentially faces competitive pressure.
* 2025/2026 Forecasts: Maintained. The Q3 results align with our expectations for loss narrowing and BC ramp-up.

Investment View

1. Core Investment Logic: The "BC Alpha"

Longi Green Energy is no longer just a beta play on the solar industry’s growth. It is an alpha play on technological disruption. The market has largely punished Longi for the industry-wide downturn, failing to fully price in the transformative potential of its BC strategy.

• From Commodity to Premium: By shifting its product mix to BC, Longi is escaping the commodity trap. BC modules are not just "solar panels"; they are high-performance energy generators with aesthetic value. This allows Longi to rebuild its brand equity and pricing power.
• Margin Reconstruction: Our model assumes that as BC shipments reach 50%+ of total volume in 2026, the blended gross margin will recover to double digits (projected 10.73% in 2026E). This margin expansion is the primary driver of the projected swing from loss to profit.
• Cash Flow Durability: The strong operating cash flow in 3Q25 proves that Longi can self-fund its transition. This reduces dilution risk and financial distress risk, making it a safer hold than leveraged competitors.

2. Catalysts for Re-rating

Several catalysts could drive the stock price higher in the coming 6-12 months:
1. Quarterly Profitability Milestone: The first quarter of single-digit or positive net profit (likely late 2025 or early 2026) will serve as a major psychological and fundamental turning point for investors.
2. BC Cost Parity Announcement: If Longi announces that BC production costs have reached parity with TOPCon, it would remove the last major barrier to mass adoption and trigger a surge in demand.
3. Industry Supply Clearance: Official policy announcements from Beijing regarding capacity caps or energy consumption limits for PV manufacturing would accelerate the exit of inefficient players, benefiting Longi’s market share.
4. Overseas Breakthroughs: Significant new contracts in Europe or emerging markets for BC modules would validate the global appeal of the technology.

3. Valuation Framework

We employ a hybrid valuation approach, combining Price-to-Book (P/B) for the current trough period and Price-to-Earnings (P/E) for the recovery phase.

• P/B Analysis: Longi is currently trading at ~2.8x P/B. Historically, during cyclical troughs, leading PV manufacturers have traded between 2.0x and 3.5x P/B. Given Longi’s superior technology and balance sheet, a multiple of 3.0x-3.5x is justified. This implies a fair value range of CNY 22.5 – CNY 26.3 per share, offering upside from the current CNY 21.11.
• Forward P/E Analysis: Looking to 2027, when earnings normalize, we apply a target P/E of 20-25x (consistent with mature tech-manufacturing leaders). Based on our 2027 EPS estimate of CNY 0.79, this implies a target price of CNY 15.8 – CNY 19.8. However, this static P/E view underestimates the growth optionality of BC. If BC adoption exceeds expectations, 2027 earnings could be higher, and the multiple could expand.
• Sum-of-the-Parts (SOTP): A more nuanced view values the stable wafer business at a lower multiple and the high-growth BC module business at a higher multiple. As the BC portion grows, the blended multiple should expand.

Conclusion on Valuation: The current price offers a favorable risk-reward ratio. The downside is limited by the strong book value and cash position, while the upside is significant if the BC thesis plays out as expected.

4. Strategic Recommendations for Institutional Investors

• Accumulate on Weakness: For long-term portfolios, current levels offer an attractive entry point. The market is overly focused on short-term losses and underestimating the structural shift to BC.
• Monitor Quarterly BC Mix: The key metric to watch in upcoming earnings calls is the percentage of BC shipments and the gross margin differential between BC and non-BC products. A widening differential is a bullish signal.
• Watch CapEx Discipline: Continue to monitor capital expenditure. Prudent spending (as seen in 3Q25) is positive. Aggressive expansion into non-core areas would be a negative signal.
• Hedge Policy Risk: Given the geopolitical sensitivity, investors may consider hedging exposure to trade policy news flows. However, Longi’s global diversification mitigates single-market risk.

5. Final Thoughts

Longi Green Energy stands at a crossroads. The past two years have been defined by pain, loss, and strategic pivoting. The third quarter of 2025 signals that the pivot is working. The losses are shrinking, the cash flow is strong, and the new technology is gaining traction.

For institutional investors, the question is not whether Longi will survive—it clearly will—but whether it will thrive. Our analysis suggests that Longi is well-positioned to emerge from this cycle stronger, with a more differentiated product portfolio and a cleaner competitive landscape. The "BC Revolution" is real, and Longi is leading it. We recommend maintaining a Buy rating, with a conviction that the stock will re-rate upwards as profitability returns in 2026.

Appendix: Detailed Financial Analysis

A. Balance Sheet Strength

Longi’s balance sheet remains a cornerstone of its investment case.

• Liquidity: As of 3Q25, the Company holds substantial cash and liquid assets. The operating cash flow generation of CNY 2.3 billion in Q3 alone reinforces this liquidity buffer.
• Debt Profile: The debt-to-asset ratio is managed prudently. While total liabilities have increased slightly due to operational needs, the structure is stable. The ability to generate positive operating cash flow reduces the need for expensive external financing.
• Asset Quality: The reduction in在建工程 (Construction in Progress) and the conversion into fixed assets for BC production indicate that the capital invested is becoming productive. The inventory increase is modest and manageable given the revenue scale.

B. Income Statement Trajectory

Analysis:
* 2025: Expected to be the "trough" year. Revenue declines as low-margin sales are cut. Impairments continue but are significantly lower than 2024.
* 2026: The "turnaround" year. Revenue rebounds as BC volumes scale. Gross margin expands sharply to >10% as BC mix increases and costs fall. Operating profit turns positive.
* 2027: The "growth" year. Sustainable double-digit margins and robust profit growth.

C. Cash Flow Dynamics

Analysis:
* 2025: Negative operating cash flow is expected for the full year due to working capital adjustments, but Q3’s positive surge is a leading indicator of improvement. Heavy investing cash flow reflects the final push for BC capacity.
* 2026: Strong positive operating cash flow as profitability returns. Investing cash flow moderates as major capex cycles complete.
* 2027: Mature cash cow phase. Strong operating cash flow supports dividends or share buybacks.
