Executive Summary

Longi Green Energy Technology Co., Ltd. ("Longi" or the "Company"), the global leader in monocrystalline silicon wafers and modules, released its third-quarter financial report for 2025 on October 30, 2025. The results indicate a pivotal turning point in the company’s operational trajectory, characterized by a sequential narrowing of losses and a strategic consolidation of its technological moat through Back Contact (BC) technology.

In the first three quarters of 2025, Longi reported total operating revenue of CNY 50.915 billion, representing a year-over-year (YoY) decline of 13.10%. The attributable net loss stood at CNY 3.403 billion, marking a significant reduction in losses compared to the same period in the previous year. The non-GAAP net loss was CNY 4.454 billion, also showing improvement. For the third quarter specifically (25Q3), revenue reached CNY 18.101 billion (YoY -9.78%, Quarter-over-Quarter [QoQ] -5.53%), with an attributable net loss of CNY 834 million. This represents a notable contraction in losses both YoY and QoQ. It is important to note that 25Q3 results included asset impairment provisions of CNY 894 million, which weighed on当期 profits but reflects prudent balance sheet management amidst industry restructuring.

The core investment thesis for Longi rests on two pillars: 1) The macro-economic stabilization of the photovoltaic (PV) supply chain driven by regulatory "anti-involution" measures, and 2) The Company’s decisive leadership in BC technology, which is driving a premium product mix shift.

Since July 2025, the Chinese PV industry has witnessed a concerted effort to curb destructive price competition. Regulatory interventions, including the National Development and Reform Commission’s (NDRC) recent announcements, have enforced "sales not below cost" principles. This has triggered a robust recovery in upstream prices, with polysilicon and wafer prices rising significantly by late September 2025. While module price recovery has been more lagged, the margin pressure is alleviating. Longi, with its aggressive expansion of HPBC 2.0 capacity (expected to exceed 60% of high-efficiency battery capacity by end-2025), is uniquely positioned to capture value in this recovering market. The Company’s R&D breakthroughs—achieving 27.81% efficiency for BC cells and over 26% for BC modules—reinforce its technological differentiation.

We maintain our "Recommend" rating. We project revenues of CNY 70.20 billion, CNY 82.58 billion, and CNY 90.02 billion for 2025, 2026, and 2027, respectively. Attributable net profits are forecasted to transition from a loss of CNY 4.02 billion in 2025 to profits of CNY 2.58 billion in 2026 and CNY 4.90 billion in 2027. Based on the closing price of CNY 21.76 on November 3, 2025, the stock trades at implied P/E multiples of 64x for 2026E and 34x for 2027E. Given the inflection in industry pricing and Longi’s superior technology roadmap, we view the current valuation as justified by the anticipated earnings recovery and long-term competitive advantage.

Key Takeaways

1. Financial Performance: Sequential Improvement and Impairment Clarity

The 25Q3 financial results demonstrate that Longi is navigating the trough of the industry cycle with improving resilience. While top-line revenue continues to face headwinds due to lower average selling prices (ASPs) across the industry, the bottom line is stabilizing.

Revenue and Profitability Trends:
* 9M 2025 Overview: Total revenue of CNY 50.915 billion (-13.10% YoY). The decline is primarily attributed to the substantial drop in PV product prices throughout 2024 and early 2025, which outweighed volume growth in certain segments.
* 25Q3 Specifics: Revenue of CNY 18.101 billion. The QoQ decline of 5.53% reflects seasonal adjustments and continued price pressure in the early part of the quarter before the late-Q3 price hikes took full effect.
* Loss Narrowing: The attributable net loss of CNY 834 million in 25Q3 is a critical signal. Compared to the deeper losses in prior quarters, this indicates that gross margins are beginning to stabilize. The non-GAAP loss of CNY 1.15 billion also narrowed sequentially.
* Asset Impairments: The Company recognized CNY 894 million in asset impairment provisions in 25Q3. This figure, while impacting net income, suggests that Longi is actively clearing out older, less efficient inventory and capacity values. This "kitchen sinking" approach reduces the overhang on future quarters, allowing for cleaner profitability metrics starting in 2026.

The forecast table above illustrates the expected V-shaped recovery. The estimated gross margin compression in 2025E (3.87%) reflects the full-year impact of low prices, particularly in H1 2025. However, the projected rebound to 13.22% in 2026E and 15.85% in 2027E underscores the expectation that price normalization and the higher-margin BC product mix will drive profitability restoration.

2. Industry Dynamics: The "Anti-Involution" Catalyst and Price Repair

The most significant external driver for Longi’s near-term outlook is the structural shift in the Chinese PV industry’s competitive landscape, termed here as "anti-involution" (countering destructive internal competition).

Regulatory Intervention and Price Floor Establishment:
In July 2025, industry associations and regulatory bodies began enforcing stricter compliance with price laws, specifically targeting sales below cash cost. This policy shift has had an immediate and tangible impact on upstream supply chain pricing.

• Polysilicon Recovery: According to the Silicon Industry Branch, by the end of September 2025, the average price of N-type recycled material reached CNY 53,200/ton, and granular silicon reached CNY 50,500/ton. These figures represent increases of 55% and 51% respectively, compared to end-June 2025 levels. This sharp rebound indicates that producers have successfully pushed prices back above the comprehensive cost line, halting the cash-burn dynamics that plagued the sector in H1 2025.
• Wafer Price Transmission: The price increase transmitted rapidly to the wafer segment. Data from Infolink shows that the average price of 182210mm N-type wafers rose to CNY 1.40/piece by late September 2025, a 36%* increase from end-June. As Longi is a dominant player in the wafer market, this price repair directly improves the utilization value of its existing capacity and supports better margins in its merchant wafer sales.
• Module Lag and Future Outlook: Downstream module prices have exhibited stickiness. The average price for TOPCon modules was CNY 0.693/W in late September, only a 2% increase from June. This lag is typical, as module contracts are often longer-term and downstream developers resist rapid price hikes. However, the sustained increase in upstream costs (silicon and wafers) creates inevitable upward pressure on module ASPs.
• Policy Reinforcement: In October 2025, the NDRC and the State Administration for Market Regulation issued a joint announcement on governing disorderly price competition. This reinforces the government’s commitment to maintaining a healthy market order. For institutional investors, this signals a reduced risk of further margin erosion and provides visibility for earnings recovery in 2026.

Implication for Longi:
Longi’s integrated model allows it to capture value at multiple stages. While the module segment remains under pressure, the improved profitability in the wafer segment (due to the 36% price hike) acts as a buffer. As module prices eventually catch up to reflect higher input costs, Longi’s integrated margins are poised for expansion. The "anti-involution" environment favors large, compliant players like Longi over smaller, inefficient competitors who cannot sustain operations above the cost floor.

3. Strategic Moat: BC Technology Leadership and Capacity Upgrade

Longi’s long-term competitive advantage is increasingly defined by its bet on Back Contact (BC) technology. Unlike the industry’s widespread adoption of TOPCon, Longi has doubled down on BC, arguing that it offers superior aesthetics, higher efficiency potential, and better degradation performance. The 2025 results validate this strategy as BC products begin to scale.

Technological Breakthroughs:
* Record Efficiency: In H1 2025, Longi’s R&D team achieved a BC cell efficiency of 27.81% and a BC module efficiency exceeding 26%. These figures set new global records for crystalline silicon cells and modules. This technical lead is not merely incremental; it represents a significant gap over mainstream TOPCon efficiencies (typically ~25-25.5% for mass production modules).
* Differentiation: The higher efficiency translates to higher power density, which is crucial for distributed generation (rooftop) markets where space is constrained. It also allows for premium pricing in high-value segments, insulating Longi from the commoditization pressures facing standard PERC and TOPCon products.

Capacity Expansion and Product Mix Shift:
* HPBC 2.0 Ramp-up: The Company is aggressively expanding its High-Performance BC (HPBC) 2.0 capacity. Management guidance indicates that by the end of 2025, HPBC 2.0 high-efficiency battery capacity will account for over 60% of its total battery capacity.
* Structural Upgrade: This rapid conversion of capacity signifies a complete product structure upgrade. By exiting older, less efficient lines and focusing on HPBC 2.0, Longi is lowering its average unit cost through learning curves and economies of scale specific to BC manufacturing.
* Market Penetration: The penetration rate of BC products is accelerating. Longi is leading the layout in high-value markets, particularly in Europe and domestic distributed projects, where customers are willing to pay a premium for efficiency and aesthetics. This strategic positioning allows Longi to avoid the fiercest price wars in the utility-scale TOPCon segment.

Table 2: Technological & Capacity Milestones

The commitment to BC technology is a double-edged sword in the short term due to higher initial CAPEX and learning curve costs, but it positions Longi as the technology leader in the next cycle. As the industry matures, efficiency gains become the primary driver of Levelized Cost of Energy (LCOE) reduction, favoring BC architecture.

4. Operational Efficiency and Balance Sheet Health

Despite the losses, Longi maintains a robust balance sheet, which is critical for surviving the industry downturn and funding the BC transition.

Cash Flow and Liquidity:
* Operating Cash Flow: The forecast indicates a turnaround in operating cash flow, from negative CNY 4.7 billion in 2024 to positive CNY 7.2 billion in 2025E, and further strengthening to CNY 13.2 billion in 2026E. This improvement is driven by better working capital management and the eventual recovery in margins.
* Cash Reserves: As of the latest reporting period, Longi holds substantial monetary funds (estimated at CNY 57.15 billion by end-2025E). This liquidity cushion provides the flexibility to continue R&D spending and capacity upgrades without excessive reliance on external debt, even during periods of negative net income.
* Debt Management: The Company’s asset-liability ratio is projected to remain stable around 60-62%. Long-term borrowing is increasing slightly to fund capacity upgrades, but the overall leverage remains manageable given the strong cash position.

Cost Control:
* Expense Reduction: Sales expenses are forecasted to decrease from CNY 2.9 billion in 2024 to CNY 1.9 billion in 2025E, reflecting tighter cost controls. Management expenses are also optimized.
* R&D Investment: Crucially, R&D expenses remain robust (CNY 1.54 billion in 2025E, rising to CNY 1.98 billion in 2027E). This demonstrates that Longi is protecting its innovation engine despite profit pressures, ensuring its technological lead is maintained.

Risks / Headwinds

While the outlook is improving, institutional investors must consider several persistent risks that could derail the recovery thesis.

1. Downstream Demand Uncertainty

The global PV demand growth rate is subject to macroeconomic conditions, interest rate environments, and policy shifts in key markets.
* Interest Rates: High interest rates in Europe and North America can dampen the economics of residential and commercial solar projects, potentially slowing the adoption of premium BC modules.
* Grid Constraints: In many major markets, grid congestion is becoming a bottleneck for new solar installations. If grid infrastructure upgrades lag behind capacity additions, curtailment risks may reduce the effective demand for new modules.
* Forecast Risk: If global installations in 2026 fall short of expectations, the anticipated price recovery in modules may be muted, prolonging the period of margin pressure.

2. Intensifying Market Competition

Despite "anti-involution" policies, the PV industry remains highly competitive.
* TOPCon Oversupply: The vast majority of the industry has invested in TOPCon capacity. If TOPCon prices remain depressed due to oversupply, it could cap the pricing power of BC modules. While BC is differentiated, it still competes for the same total wallet share of developers.
* New Entrants in BC: Other major manufacturers are beginning to explore or announce BC/HJT hybrid technologies. If competitors rapidly close the efficiency gap or achieve lower manufacturing costs for BC, Longi’s first-mover advantage could erode.
* Price War Recurrence: If regulatory enforcement weakens, companies might revert to predatory pricing to clear inventory, reigniting the "involution" cycle.

3. International Trade and Geopolitical Risks

Longi has significant exposure to international markets, particularly Europe and the US.
* Tariffs and Trade Barriers: The EU’s anti-subsidy investigations and potential tariffs on Chinese solar products pose a direct threat to margins. The US Inflation Reduction Act (IRA) favors domestic manufacturing, limiting Longi’s direct access to the lucrative US market unless it establishes local production (which carries its own execution risks).
* Supply Chain Decoupling: Increasing geopolitical tensions may lead to further decoupling of supply chains, forcing Longi to navigate complex compliance requirements or face exclusion from certain markets.
* Currency Fluctuations: As a major exporter, fluctuations in the RMB exchange rate can impact the competitiveness of Longi’s products and translate into foreign exchange gains or losses.

4. Technology Execution Risk

• Yield Rates: Scaling up HPBC 2.0 production to achieve high yields and low costs is technically challenging. Any delays in reaching target yield rates or unexpected manufacturing defects could impact profitability and delay the expected margin expansion.
• Customer Acceptance: While BC offers higher efficiency, it comes at a higher cost. If the premium priced by the market does not adequately compensate for the higher manufacturing cost, the economic viability of the BC strategy could be questioned.

Rating / Sector Outlook

Sector Outlook: From Consolidation to Rationalization

The global photovoltaic sector is transitioning from a phase of chaotic expansion and price destruction to one of consolidation and rationalization. The "anti-involution" policies in China are a catalyst for this structural change. We expect the following trends to define the sector in 2026-2027:

1. Supply Side Clearing: High-cost, inefficient capacity will be permanently exited. The barrier to entry has risen due to technological complexity (shift to BC/HJT) and capital intensity. This will reduce industry fragmentation.
2. Price Stabilization: With polysilicon and wafer prices anchored above cost, the floor for module prices is established. We anticipate a gradual, sustainable increase in module ASPs, driven by cost-push factors and improved demand-supply balance.
3. Technology Differentiation: The era of homogeneous competition is ending. Companies with proprietary, high-efficiency technologies (like Longi’s BC) will command premium valuations and margins. Generic TOPCon producers will face compressed margins akin to commodity manufacturers.
4. Global Diversification: Successful players will need to diversify manufacturing footprints to mitigate trade risks. However, Chinese firms will retain a cost and technology advantage that is difficult to replicate fully overseas in the short term.

Company Rating: Recommend (Maintained)

We maintain our "Recommend" rating for Longi Green Energy.

Valuation Analysis:
* Current Price: CNY 21.76 (as of Nov 3, 2025).
* Forward P/E: Based on our estimates, the stock trades at 64x 2026E EPS and 34x 2027E EPS.
* Justification: While a 64x P/E may appear elevated compared to historical averages for mature manufacturing firms, it is justified by:
1. Earnings Inflection: The transition from significant losses in 2024-2025 to robust profitability in 2026-2027 represents a classic cyclical turnaround play.
2. Technology Premium: Longi’s leadership in BC technology warrants a valuation premium over peers stuck in the TOPCon commoditization trap.
3. Market Leadership: As the industry consolidates, Longi’s market share and pricing power are expected to strengthen.
4. PB Ratio: The Price-to-Book ratio of ~2.8x for 2026E is reasonable for a technology-led manufacturer with strong ROE prospects (projected 7.81% in 2027).

Peer Comparison Context:
Compared to peers who are heavily exposed to standard TOPCon, Longi’s diversified technology portfolio and stronger balance sheet provide a safer investment profile with higher upside potential from the BC adoption curve. The market is currently pricing in the recovery, but we believe the magnitude of the 2026-2027 earnings beat could be underestimated if BC penetration accelerates faster than expected.

Investment View

Core Investment Logic

1. Cyclical Turnaround with Policy Support:
The most immediate investment driver is the macro-level stabilization of the PV supply chain. The regulatory crackdown on below-cost selling has effectively put a floor under prices. For Longi, this means the worst of the margin compression is likely behind us. The sequential narrowing of losses in 25Q3 is the first concrete evidence of this turnaround. Investors should view the 2025 loss as a transitional phase, with 2026 marking the return to sustainable profitability. The "anti-involution" narrative is not just rhetoric; it is translating into real price increases in silicon and wafers, which will inevitably flow through to module margins.

2. Structural Alpha via BC Technology:
Longi is not just riding the industry beta; it is generating alpha through its BC strategy. The decision to pivot heavily to HPBC 2.0 is a contrarian bet that is paying off. As the market saturates with TOPCon, the differentiation offered by BC (higher efficiency, better aesthetics, lower degradation) becomes more valuable. Longi’s record-breaking efficiency numbers are not just lab curiosities; they are the foundation of a premium product lineup that can command higher prices. The projected 60%+ capacity share for HPBC 2.0 by end-2025 means that by 2026, the majority of Longi’s output will be from this high-margin, high-tech segment. This structural shift will drive gross margin expansion beyond the industry average.

3. Financial Resilience and Balance Sheet Strength:
In a capital-intensive industry undergoing a shakeout, balance sheet strength is a competitive advantage. Longi’s ability to maintain positive operating cash flow projections and hold significant cash reserves allows it to weather the storm while competitors may face liquidity crises. This financial health enables Longi to continue investing in R&D and capacity upgrades without diluting shareholders or taking on excessive debt. The projected improvement in ROE from -7.07% in 2025E to 7.81% in 2027E highlights the operational leverage inherent in the business model as volumes stabilize and margins recover.

Strategic Implications for Investors

Short-Term (6-12 Months):
* Monitor Price Trends: Keep a close watch on monthly polysilicon, wafer, and module price indices. Sustained stability or increases in these prices will confirm the recovery thesis.
* Q4 2025 & Q1 2026 Results: Look for further narrowing of losses and signs of gross margin expansion in the wafer segment. The impact of the October regulatory announcements should start appearing in Q4 data.
* BC Shipment Mix: Track the percentage of BC modules in total shipments. An accelerating mix shift will be a positive catalyst for re-rating.

Medium-Term (1-3 Years):
* Profitability Realization: The key metric will be the realization of the projected CNY 2.58 billion net profit in 2026. If Longi can achieve or exceed this, the current valuation will look attractive.
* Global Market Share: Assess Longi’s ability to maintain or grow its market share in key regions (Europe, Asia-Pacific) despite trade barriers. Success in penetrating high-value distributed generation markets globally will be crucial.
* Technology Leadership: Monitor whether Longi can maintain its efficiency lead over competitors. Any sign of competitors catching up rapidly could compress the BC premium.

Conclusion

Longi Green Energy stands at a critical juncture. The company has successfully navigated the deepest part of the industry downturn, evidenced by the sequential loss reduction in 25Q3. The combination of regulatory-induced price stabilization and its own strategic pivot to BC technology creates a compelling dual-engine growth story.

While risks related to demand, competition, and geopolitics remain, Longi’s strong balance sheet, technological leadership, and dominant market position provide a robust defense and a clear path to offense. The projected return to profitability in 2026, driven by higher-margin BC products and normalized supply chain prices, supports our Recommend rating. Institutional investors should consider accumulating positions on dips, viewing the current volatility as an opportunity to buy into a market leader at the onset of a cyclical and structural upturn.

The investment case is no longer about survival; it is about the magnitude of the recovery and the sustainability of the BC-driven premium. With clear visibility on price floors and a differentiated product roadmap, Longi is well-positioned to outperform the broader PV sector in the coming cycle.

Appendix: Detailed Financial Analysis & Forecasts

Income Statement Analysis

Revenue Trajectory:
The projected revenue decline of 15% in 2025 (to CNY 70.2 billion) reflects the full-year impact of lower ASPs. However, the 17.6% growth forecast for 2026 (to CNY 82.6 billion) assumes both volume growth and modest price recovery. The 9% growth in 2027 (to CNY 90.0 billion) suggests a maturing market where volume growth slows but value retention improves.

Margin Expansion Drivers:
* 2024A Gross Margin (7.44%): Depressed by severe price wars and inventory write-downs.
* 2025E Gross Margin (3.87%): Expected to be the trough. H1 2025 margins were severely impacted by low prices. H2 2025 should see improvement due to the July-September price hikes, but the full-year average remains low.
* 2026E Gross Margin (13.22%): A significant jump driven by:
1. Higher wafer prices sustaining margins in the upstream segment.
2. Module prices catching up to input costs.
3. Higher contribution from high-margin BC products.
4. Lower unit costs from HPBC 2.0 scale effects.
* 2027E Gross Margin (15.85%): Further expansion as BC becomes the dominant product mix and operational efficiencies maximize.

Expense Management:
* Selling Expenses: Projected to drop significantly in 2025E (CNY 1.89 billion vs CNY 2.91 billion in 2024A) due to cost-cutting measures.
* R&D Expenses: Maintained at high levels (CNY 1.54 billion in 2025E, growing to CNY 1.98 billion in 2027E). This ratio of R&D to Revenue increases, highlighting the company’s focus on innovation as a core strategy.
* Asset Impairment: The large impairment in 2024A (CNY 8.7 billion) and estimated CNY 2.5 billion in 2025E cleans up the balance sheet. By 2026E, impairments are forecasted to drop to CNY 1.0 billion, reducing the drag on net income.

Balance Sheet Strength

Liquidity Position:
* Monetary Funds: Projected to grow from CNY 53.2 billion (2024A) to CNY 77.9 billion (2027E). This massive cash pile is a strategic asset, allowing Longi to fund CAPEX internally and withstand prolonged downturns.
* Current Ratio: Improving from 1.49 (2024A) to 1.75 (2027E), indicating strengthening short-term solvency.
* Quick Ratio: Improving from 1.15 to 1.40, showing that even excluding inventory, the company can cover its short-term liabilities comfortably.

Asset Quality:
* Inventory: Inventory levels are managed tightly, with turnover days projected to stabilize around 75-85 days. This prevents excessive exposure to price declines.
* Fixed Assets: Fixed assets are projected to decline from CNY 36.2 billion (2024A) to CNY 28.9 billion (2027E). This reflects the depreciation of older assets and a shift towards more efficient, potentially leased or jointly developed new capacity, or simply a more asset-light approach in certain segments.

Cash Flow Dynamics

Operating Cash Flow (OCF):
* 2024A: Negative CNY 4.7 billion due to losses and working capital outflows.
* 2025E: Positive CNY 7.2 billion. The turnaround is driven by improved working capital management (receivables collection) and the reduction in losses.
* 2026E-2027E: Strong positive OCF of CNY 13.2 billion and CNY 15.4 billion respectively. This cash generation capability will support dividends (projected dividend yield of 0.60% in 2027E) and future investments.

Capital Expenditure (CAPEX):
* CAPEX remains significant (CNY 7.8 billion in 2025E) to fund the HPBC 2.0 expansion. However, it is projected to decrease to CNY 4.2 billion in 2026E and 2027E as the major capacity build-out completes. This reduction in CAPEX intensity will further boost free cash flow in the later years of the forecast period.

Valuation Metrics Deep Dive

P/E Ratio:
* The high 2026E P/E of 64x is a function of the low base of earnings (CNY 2.58 billion) as the company emerges from losses. As earnings grow to CNY 4.90 billion in 2027E, the P/E compresses to a more reasonable 34x. This rapid de-rating of the P/E multiple as earnings grow is characteristic of cyclical recovery stocks.

P/B Ratio:
* Trading at ~2.8x Book Value in 2026E. Given the projected ROE of 4.38% in 2026 and 7.81% in 2027, the P/B is supported. If ROE continues to rise towards double digits in the long term, the P/B multiple could expand further.

EV/EBITDA:
* The EV/EBITDA multiple drops from 30.36x in 2025E to 12.14x in 2026E. This sharp decline reflects the recovery in EBITDA from CNY 4.6 billion to CNY 11.6 billion. An EV/EBITDA of 12x is attractive for a technology leader with strong cash flows.

Final Thoughts on Risk-Adjusted Returns

Investing in Longi at this stage involves balancing the certainty of its balance sheet and technology against the uncertainty of the pace of industry recovery. The "Recommend" rating implies that the upside potential from the earnings inflection and BC premium outweighs the downside risks of prolonged price stagnation.

For institutional portfolios, Longi serves as a high-beta play on the PV sector’s recovery, but with a defensive quality provided by its cash position and technological moat. It is preferable to pure-play TOPCon manufacturers who lack the differentiation to escape commoditization. The key monitoring variable remains the spread between BC module prices and TOPCon module prices. If this spread widens or remains stable while BC costs decline, Longi’s earnings upside could exceed our current forecasts. Conversely, if the spread collapses, the investment thesis would need to be re-evaluated.

Given the current data, the probability-weighted outcome favors a successful transition to a higher-margin, technology-led business model, justifying the current valuation and supporting a positive outlook for 2026-2027.
