Executive Summary

Longi Green Energy Technology Co., Ltd. ("Longi" or the "Company") released its Third Quarter 2025 financial results on October 30, 2025. The report signals a critical inflection point in the company’s operational and financial trajectory, characterized by a significant narrowing of losses, robust cash flow generation, and the accelerated commercialization of its next-generation Back Contact (BC) technology.

Key Performance Highlights (9M 2025 & Q3 2025):
* Revenue: 9M 2025 revenue stood at RMB 50.9 billion, a year-over-year (YoY) decline of 13%. Q3 2025 revenue was RMB 18.1 billion, down 10% YoY and 6% quarter-over-quarter (QoQ).
* Profitability: The Company reported a net loss attributable to shareholders of RMB 3.4 billion for the first nine months, representing a 48% reduction in losses compared to the same period last year. In Q3 alone, the net loss narrowed to RMB 834 million, a 34% YoY improvement and a 26% QoQ improvement.
* Margins: Gross margin improved sequentially by 3.3 percentage points (pct) to 4.89% in Q3, driven by rising upstream prices and product mix optimization.
* Cash Flow: Operating cash flow turned positive for the second consecutive quarter, reaching RMB 2.3 billion in Q3. Cash reserves remained strong at RMB 51.7 billion, with a debt-to-asset ratio of 62.43%, underscoring financial resilience amidst industry consolidation.

Strategic Pivot & Investment Thesis:
The core investment thesis for Longi has shifted from pure scale expansion to technology-led differentiation and profitability recovery. Two primary drivers are reshaping the Company’s outlook:
1. Industry "Anti-Involution" Dynamics: Since June 2025, coordinated efforts within the photovoltaic (PV) supply chain to curb irrational price competition ("anti-involution") have led to a ~50% increase in silicon wafer prices in Q3. This structural shift is directly repairing margins across the upstream segment.
2. BC 2.0 Technology Leadership: Longi’s HPBC 2.0 products are experiencing rapid volume growth. With cumulative BC module sales of 14.48 GW in 9M 2025 and an expected >60% share of high-efficiency battery capacity by year-end 2025, Longi is successfully transitioning to a high-value, differentiated product portfolio. This technological moat is expected to sustain premium pricing and superior margins relative to mainstream PERC and TOPCon competitors.

Valuation & Rating:
We maintain our "BUY" rating on Longi Green Energy. We have adjusted our net profit forecasts for 2025-2027 to RMB -3.74 billion, RMB 4.40 billion, and RMB 6.18 billion, respectively. The adjustment reflects the faster-than-expected margin recovery in Q3 and the accelerating penetration of BC technology. Despite near-term revenue headwinds due to industry-wide destocking and price adjustments, the Company’s path to profitability in 2026 is becoming increasingly visible. The current valuation offers an attractive entry point for institutional investors seeking exposure to the leading player in the next-generation PV technology cycle.

Key Takeaways

1. Financial Performance: Loss Narrowing Accelerates Amidst Revenue Contraction

The third-quarter results demonstrate that Longi is successfully navigating the trough of the PV industry cycle. While top-line revenue continues to face pressure from lower average selling prices (ASPs) and reduced shipment volumes compared to the peak demand periods, the bottom-line performance shows marked improvement.

1.1 Revenue Analysis: Contextualizing the Decline

• 9M 2025 Revenue: RMB 50.9 billion (-13% YoY).
• Q3 2025 Revenue: RMB 18.1 billion (-10% YoY, -6% QoQ).

The sequential decline in Q3 revenue is primarily attributed to the high base effect from Q2 2025, which saw a rush in domestic installations ("grabbing installation" phenomenon) ahead of potential policy shifts or grid connection deadlines. This seasonal volatility is typical in the Chinese PV market but does not reflect a deterioration in underlying demand fundamentals.

Note: Q2 figures are derived based on Q3 sequential data provided in the report.

The revenue contraction is also a strategic choice. Longi has actively optimized its product mix, prioritizing higher-margin BC modules over commoditized standard products. This deliberate shift may suppress total wattage shipments in the short term but enhances the quality of earnings and brand positioning in premium markets.

1.2 Profitability: The Turning Point

The most significant takeaway from the Q3 report is the sequential and year-over-year narrowing of losses.
* Net Loss Reduction: The Q3 net loss of RMB 834 million represents a 34% improvement YoY. More importantly, the 26% QoQ improvement indicates that operational efficiencies and price recoveries are gaining momentum.
* Gross Margin Expansion: Q3 gross margin rose to 4.89%, up 3.3 percentage points from the previous quarter. This expansion is driven by two factors:
1. Upstream Price Recovery: The "anti-involution" initiative has stabilized and raised silicon wafer prices.
2. Product Mix Shift: Increased contribution from high-margin HPBC 2.0 modules.

This margin recovery is critical. It validates the hypothesis that the industry floor has been reached and that leaders with cost advantages and technological premiums can restore profitability even before a full-scale demand surge.

2. Operational Analysis: Supply Chain Stabilization and "Anti-Involution" Effects

The Chinese PV industry has suffered from severe overcapacity and destructive price wars since late 2023. However, Q3 2025 marks a pivotal change in industry dynamics, driven by regulatory guidance and industry self-discipline aimed at ending "involution" (neijuan).

2.1 The "Anti-Involution" Catalyst

Since June 2025, major industry players, supported by industry associations, have moved to restrict below-cost bidding and rationalize production schedules. This has had an immediate impact on upstream pricing:
* Silicon Wafer Prices: According to InfoLink, silicon wafer prices increased by approximately 50% in Q3 2025.
* Impact on Longi: As a vertically integrated leader with significant wafer capacity, Longi benefits disproportionately from this price stabilization. The company’s wafer business, which had been a drag on earnings due to severe losses, saw its loss magnitude narrow significantly in Q3.

2.2 Shipment Volumes: Stability Amidst Transition

• Silicon Wafers:
  • 9M 2025 External Sales: 38.15 GW.
  • Q3 2025 External Sales: 13.43 GW (flat QoQ).
  • Analysis: The stability in wafer shipments despite the price hike suggests strong demand for Longi’s high-quality wafers, particularly from external cell manufacturers who rely on Longi’s technological leadership in N-type wafer quality.
• Battery Modules (Cells & Modules):
  • 9M 2025 External Sales: 63.43 GW.
  • Q3 2025 Estimated External Sales: 21-22 GW (slight QoQ decline).
  • Analysis: The slight dip in module shipments is consistent with the post-Q2 rush normalization. However, the focus is shifting from volume to value. The composition of these shipments is increasingly skewed towards BC products, which carry higher ASPs and margins.

3. Strategic Driver: BC 2.0 Technology Ramp-Up and Differentiation

Longi’s bet on Back Contact (BC) technology is moving from the pilot phase to mass commercialization. This strategic pivot is the core differentiator that separates Longi from competitors still heavily reliant on TOPCon technology, which is facing rapid commoditization and margin compression.

3.1 HPBC 2.0: Rapid Volume Growth

• Cumulative Sales: In the first nine months of 2025, Longi sold 14.48 GW of BC modules.
• Q3 Momentum: HPBC 2.0 production and sales achieved rapid sequential growth in Q3. This indicates that manufacturing yields have stabilized, and market acceptance is accelerating.
• Competitive Advantage: HPBC 2.0 offers superior aesthetics (no front busbars), higher efficiency, and better temperature coefficients. These features are highly valued in distributed generation (residential and C&I) markets, particularly in Europe and other premium overseas markets where Longi holds strong brand equity.

3.2 Capacity Expansion and Roadmap

Longi is aggressively expanding its BC capacity to meet growing demand and achieve economies of scale.

By the end of 2025, more than 60% of Longi’s high-efficiency battery capacity will be dedicated to HPBC 2.0. This structural shift in capacity allocation is crucial for several reasons:
1. Margin Protection: BC technology commands a premium over standard TOPCon. As the mix shifts, the blended average margin of the module business will improve structurally.
2. Barrier to Entry: BC technology is more complex to manufacture than TOPCon. Longi’s early mover advantage and proprietary process know-how create a significant moat against latecomers.
3. Future-Proofing: BC is widely regarded as the platform technology for future iterations (e.g., tandem cells with perovskite). By establishing dominance in BC now, Longi positions itself for the next leap in efficiency beyond the theoretical limits of single-junction silicon.

3.3 Global Channel and Brand Leverage

Longi’s ability to sell premium BC products is underpinned by its established global distribution network and brand recognition. Unlike smaller competitors who must compete on price alone, Longi can leverage its brand to educate customers on the value proposition of BC technology (higher lifetime yield, aesthetic appeal). This "solution-based" sales approach allows Longi to maintain pricing power even in a competitive market.

4. Financial Health: Robust Cash Flow and Balance Sheet Strength

In a cyclical downturn, cash is king. Longi’s financial discipline has ensured it emerges from the trough with a stronger balance sheet relative to many peers who are facing liquidity crises.

4.1 Operating Cash Flow Turnaround

• Q3 2025 OCF: RMB 2.3 billion.
• Trend: Positive for two consecutive quarters and improving.
• Drivers:
  • Improved working capital management.
  • Reduced inventory levels as the company aligns production with realistic demand forecasts.
  • Better collection of receivables.
  • Cost control measures impacting cash outflows.

The return to positive operating cash flow is a vital signal. It indicates that the core business is generating cash, reducing reliance on external financing to fund operations. This self-sufficiency provides the flexibility to invest in R&D and capacity upgrades without diluting shareholders or taking on excessive debt.

4.2 Liquidity and Solvency

• Cash Reserves: RMB 51.7 billion (as of end-Q3 2025).
• Debt-to-Asset Ratio: 62.43%.
• Assessment: The debt level is considered low relative to industry peers, many of whom have seen their leverage ratios spike above 70-80% due to accumulated losses and continued capex. Longi’s conservative financial posture during the boom years has paid off, providing a "war chest" to survive the downturn and acquire distressed assets or talent if opportunities arise.

This financial robustness guarantees Longi’s ability to "cross the cycle." While weaker competitors may be forced to cut R&D or halt expansion, Longi can continue to innovate and prepare for the next upcycle.

Risks / Headwinds

While the outlook is improving, institutional investors must remain cognizant of the following risks that could impede Longi’s recovery trajectory:

1. Technology Development Risks

• Yield and Cost Challenges: BC technology is inherently more complex than PERC or TOPCon. Any delays in achieving target yields or cost reductions in HPBC 2.0 mass production could erode the expected margin benefits.
• Next-Gen Competition: While BC is the current focus, rapid advancements in competing technologies (e.g., HJT improvements, Perovskite-Silicon Tandems by competitors) could challenge Longi’s technological lead. If competitors achieve comparable efficiency at lower costs, Longi’s premium may compress.

2. International Trade and Geopolitical Environment

• Tariffs and Trade Barriers: Longi derives a significant portion of its revenue from overseas markets (Europe, US, Asia-Pacific). Escalating trade tensions, such as new anti-dumping/countervailing duties (AD/CVD) in the US or Europe, or supply chain decoupling initiatives, could restrict market access or force costly supply chain reconfiguration.
• Policy Uncertainty: Changes in subsidy policies in key markets (e.g., changes to net metering in Europe or import restrictions in India) could dampen demand for premium modules.

3. Industry Demand and Supply Dynamics

• Demand Miss: If global PV installation growth falls short of expectations due to macroeconomic slowdowns, high interest rates, or grid congestion issues, the anticipated demand for premium BC modules may not materialize at the projected pace.
• Persistent Overcapacity: Although "anti-involution" measures are helping, the industry still faces massive structural overcapacity. If price discipline breaks down again, or if idle capacity is restarted prematurely, prices could fall back to unsustainable levels, delaying profitability recovery.

4. Execution Risks in Capacity Ramp-up

• Capex Efficiency: The rapid expansion of BC capacity requires significant capital expenditure. Any inefficiencies in project execution, delays in equipment delivery, or integration issues with joint venture partners (Yingfa, Pingmei) could impact the timeline for reaching the >60% BC capacity target.

Rating / Sector Outlook

Sector Outlook: From Consolidation to Quality Growth

The global photovoltaic sector is transitioning from a phase of chaotic expansion to structured consolidation.
* Supply Side: The "anti-involution" trend is likely to persist, supported by both market forces (bankruptcy of inefficient players) and regulatory guidance. This will lead to a healthier supply-demand balance by late 2025/early 2026.
* Technology Side: The industry is bifurcating. Standard TOPCon is becoming a commodity with thin margins. Next-generation technologies (BC, HJT, Tandem) are becoming the primary drivers of alpha. Investors should favor companies with clear technological leadership and the financial strength to sustain R&D.
* Price Trend: We expect module prices to stabilize and potentially rise modestly in 2026 as high-cost capacity exits and premium product mixes increase. However, a return to the super-profits of 2022 is unlikely; the new normal will be moderate, sustainable returns for efficient leaders.

Company Rating: BUY

We maintain our BUY rating on Longi Green Energy.

Rationale for Rating:
1. Valuation Attractiveness: The stock is trading at a discount relative to its historical averages and its intrinsic value as a technology leader, largely reflecting the transient losses of 2024-2025. As profitability returns in 2026, the multiple expansion potential is significant.
2. Visible Catalysts: The Q3 margin improvement and BC ramp-up are tangible, near-term catalysts that de-risk the investment thesis.
3. Market Leadership: Longi remains the dominant player in wafer technology and is rapidly becoming the leader in BC modules. In a consolidating market, scale and technology leadership translate to market share gains.
4. Financial Safety: The strong balance sheet provides a margin of safety that many peers lack.

Consensus View:
Market sentiment is turning positive. Recent analyst reports from major institutions have shifted from "Hold/Neutral" to "Buy/Accumulate," reflecting confidence in the turnaround. The average rating score over the past three months is ~1.09 (where 1.00 = Buy), indicating strong institutional support.

Investment View

1. Core Investment Logic: The "Quality Over Quantity" Shift

Longi’s investment case is no longer about being the biggest producer of generic solar modules. It is about being the most profitable producer of advanced solar solutions.

• The BC Moat: Back Contact technology is not just an incremental improvement; it is a architectural change that offers distinct advantages in aesthetics and efficiency. Longi’s decision to go all-in on BC, while controversial when TOPCon was the hype, is now paying off. The market is beginning to recognize the value of BC, particularly in distributed generation segments where aesthetics and space efficiency matter.
• Pricing Power: As BC becomes a larger part of Longi’s mix, the company gains pricing power. It is no longer competing solely on $/Watt with commoditized TOPCon modules. It is selling a differentiated product with a unique value proposition. This allows Longi to decouple its margins from the brutal price wars in the standard segment.
• Vertical Integration Optimization: Longi is optimizing its vertical integration. Instead of using all wafers internally, it sells high-quality wafers externally (capturing the upstream margin recovery) and uses its own advanced cells for high-margin BC modules. This flexible model maximizes value capture across the chain.

2. Financial Forecast and Valuation Analysis

We have updated our financial model to reflect the Q3 performance and the accelerating BC ramp.

2.1 Earnings Forecast (2025-2027)

Source: Guojin Securities Research Institute Estimates

Key Assumptions:
* 2025: Revenue declines due to lower ASPs and strategic volume moderation. Losses narrow significantly due to wafer price recovery and BC mix improvement, but full-year profitability is not yet achieved due to H1 drag.
* 2026: Revenue rebounds as BC volume scales and industry demand recovers. The company returns to profitability as BC margins fully offset remaining legacy costs.
* 2027: Sustainable growth driven by mature BC production, potential tandem cell introductions, and stable industry pricing. Margins expand to healthy levels (Net Margin ~6.7%).

2.2 Valuation Methodology

Given the cyclical nature of the industry and the transition from loss to profit, traditional P/E multiples are distorted for 2024-2025. We employ a multi-method valuation approach:

1. Forward P/E (2026/2027):

   • Based on our 2026 EPS estimate of RMB 0.58, the current price of RMB 21.51 implies a forward P/E of ~37x.
   • Based on 2027 EPS of RMB 0.82, the forward P/E is ~26x.
   • Context: While 37x may seem high, it is justified for a technology leader emerging from a cyclical trough with high growth visibility (40%+ profit growth in 2027). Historically, PV leaders have traded at 20-30x P/E during growth phases. As earnings visibility improves, the multiple may compress, but the earnings growth will drive total return.

2. Price-to-Book (P/B):

   • Current P/B (2025E) is ~2.86x.
   • Given Longi’s ROE recovery trajectory (from -6.56% in 2025E to 9.37% in 2027E), the P/B multiple is reasonable. A target P/B of 2.5-3.0x is appropriate for a high-tech manufacturing leader with strong IP.

3. DCF Sensitivity:

   • A Discounted Cash Flow analysis, assuming a WACC of 8.5% and a terminal growth rate of 2.5%, supports a fair value range consistent with the "Buy" rating, provided the 2026 profitability targets are met.

3. Strategic Implications for Institutional Investors

3.1 Timing the Cycle

We are currently in the late-stage bottoming phase of the PV cycle.
* Signal 1: Price stabilization (Wafer prices up 50% in Q3).
* Signal 2: Leader profitability improvement (Longi’s loss narrowing).
* Signal 3: Capacity rationalization (Industry "anti-involution").

Historically, the best entry point for cyclical stocks is not when earnings are at their peak, but when they are at their worst and showing signs of improvement. Longi’s Q3 report confirms this inflection.

3.2 Alpha vs. Beta

• Beta Play: Investing in Longi provides exposure to the overall recovery of the PV sector. As demand grows and prices stabilize, the entire sector benefits.
• Alpha Play: Longi offers specific alpha through its BC technology. If BC becomes the dominant mainstream technology (as PERC did), Longi’s market share and margins could exceed consensus expectations. Conversely, if BC fails to gain traction, Longi would underperform. Our analysis suggests the risk/reward favors BC success due to its technical merits and Longi’s execution capability.

3.3 Portfolio Allocation

For institutional portfolios with exposure to renewable energy:
* Overweight Longi relative to pure-play TOPCon manufacturers who lack a clear path to differentiation.
* Monitor Cash Flow: Continue to track quarterly operating cash flow as a key health indicator. Sustained positive OCF confirms the turnaround is real, not just accounting-driven.
* Watch BC Mix: Track the percentage of BC shipments in quarterly reports. A faster-than-expected rise in BC mix would be a positive catalyst for upward revision of earnings estimates.

4. Comparative Advantage: Longi vs. Peers

Longi’s combination of financial strength and technological differentiation makes it the safest and most compelling way to play the PV recovery.

5. Conclusion

Longi Green Energy’s Q3 2025 results are a testament to the company’s strategic foresight and operational resilience. The narrowing of losses, driven by the "anti-involution" price recovery and the successful ramp-up of BC 2.0 technology, marks the end of the darkest chapter in the recent PV cycle.

While revenue headwinds persist in the short term, the structural improvements in profitability and cash flow are undeniable. Longi is not just surviving the cycle; it is positioning itself to lead the next one. The transition to BC technology provides a durable competitive advantage that will drive margin expansion and market share growth in the premium segment.

For institutional investors, the current valuation offers an attractive risk-reward profile. The downside is limited by the Company’s strong balance sheet and asset value, while the upside is significant given the potential for earnings recovery in 2026 and beyond. We reaffirm our BUY rating, viewing Longi as a core holding for investors seeking exposure to the long-term growth of sustainable energy, backed by technological leadership and financial prudence.
