Executive Summary

Longi Green Energy (hereinafter referred to as "Longi" or the "Company"), the global leader in monocrystalline silicon wafers and solar modules, has demonstrated significant resilience amidst a challenging industry backdrop in the first half of 2025 (2025H1). While the broader photovoltaic (PV) sector continues to grapple with severe price compression and oversupply, Longi’s strategic pivot towards high-value Back Contact (BC) technology is beginning to yield tangible results. The Company reported a net loss attributable to shareholders of CNY 2.569 billion in 2025H1, representing a substantial year-over-year (YoY) reduction in losses compared to the same period in the previous year. This improvement underscores the effectiveness of its cost-control measures and product mix optimization, even as top-line revenue faced headwinds from declining average selling prices (ASPs).

The core investment thesis for Longi rests on three pillars: technological leadership via BC adoption, operational efficiency improvements, and an anticipated industry supply-side correction. In 2025H1, Longi successfully ramped up its HPBC 2.0 production capacity, achieving a module conversion efficiency of 24.8% and shipping approximately 4GW of these high-premium products to over 70 countries. The Company projects that by the end of 2025, HPBC 2.0 efficient capacity will account for more than 60% of its total battery capacity. Furthermore, the recent launch of HIBC (Heterojunction Interdigitated Back Contact) modules, boasting a record industrial efficiency of 25.9%, reinforces Longi’s position at the forefront of PV innovation. These technological moats are expected to protect margins and drive market share gains in the premium distributed generation segment, differentiating Longi from competitors engaged in commoditized price wars.

Financially, while we anticipate a full-year net loss of CNY 3.6 billion for 2025 (an adjustment from our previous estimate of CNY 2.4 billion due to persistent inventory impairments and lower-than-expected chain prices), the trajectory points toward a robust recovery. We forecast a return to profitability in 2026 with a net profit of CNY 2.0 billion, accelerating to CNY 4.9 billion in 2027. This turnaround is driven by the gradual exit of inefficient industry capacity, stabilization of silicon and module prices, and the higher margin contribution from BC products. Consequently, we maintain our BUY rating on Longi Green Energy. We believe the current valuation adequately reflects the near-term pain, offering an attractive entry point for institutional investors seeking exposure to the eventual cyclical upturn and the structural shift towards high-efficiency PV technologies.

Key risks to this outlook include prolonged price competition in the module sector, slower-than-expected recovery in silicon/module prices, insufficient industry self-discipline regarding capacity expansion, and potential delays in the volume ramp-up of BC products. However, given Longi’s strong balance sheet, technological lead, and global brand equity, we view the risk-reward profile as favorable for long-term capital allocation.

Key Takeaways

1. Financial Performance: Significant Loss Reduction in 2025H1 Amidst Revenue Pressure

Longi’s financial results for the first half of 2025 reflect a company navigating a severe industry downturn with disciplined execution. The primary narrative is one of loss narrowing rather than immediate profitability, which is consistent with the broader PV sector’s struggle against prices that have fallen below the cash cost of production for many manufacturers.

Revenue and Profitability Analysis:
* 2025H1 Revenue: The Company generated total operating revenue of CNY 32.813 billion, representing a YoY decline of 14.83%. This contraction is primarily attributed to the sharp decline in average selling prices across the PV supply chain, particularly for silicon wafers and modules, which outweighed the modest growth in shipment volumes.
* 2025H1 Net Profit: The net profit attributable to shareholders stood at -CNY 2.569 billion. While still negative, this represents a significant improvement (reduction in loss) compared to the deeper losses incurred in 2024H1. This indicates that the Company’s efforts to reduce costs, optimize asset utilization, and manage inventory are bearing fruit.
* Q2 2025 Sequential Improvement: A closer look at the second quarter reveals positive momentum. Q2 2025 revenue reached CNY 19.161 billion, a YoY decrease of 8.12% but a notable quarter-on-quarter (QoQ) increase of 40.35% from Q1. More importantly, the net loss in Q2 narrowed to -CNY 1.133 billion, demonstrating sequential operational improvement. This trend suggests that the worst of the pricing pressure may have passed or is being mitigated by the changing product mix.

Note: 2025H1 Gross Margin is estimated based on full-year guidance and H1 performance trends.

The divergence between volume growth and revenue decline ("incremental volume without incremental revenue") highlights the severity of the price war. However, the sequential improvement in Q2 provides early evidence that the Company is stabilizing its financial footing.

2. Operational Metrics: Volume Growth vs. Price Erosion

Despite the challenging pricing environment, Longi maintained its market leadership in terms of shipment volumes. This volume resilience is critical for maintaining factory utilization rates and spreading fixed costs, which is essential for survival during industry consolidations.

Shipment Breakdown (2025H1):
* Silicon Wafers: Total shipments reached 52.08 GW. Of this, 24.72 GW were sold externally, while the remainder was consumed internally for cell and module production. This vertical integration allows Longi to capture value at multiple stages of the supply chain, although it also exposes the Company to inventory valuation risks when prices fall rapidly.
* Battery/Modules: Total battery and module shipments amounted to 41.85 GW. Specifically, module shipments reached 39.57 GW.
* Market Position: These volumes confirm Longi’s status as a top-tier global supplier. However, the report explicitly notes that these shipments occurred in an environment where market prices for main PV products fell below industry cost lines. This dynamic resulted in operating losses despite the volume growth, a phenomenon characteristic of the current "clearing phase" of the PV cycle.

The ability to move nearly 40 GW of modules in a depressed market speaks to the strength of Longi’s global distribution network and brand recognition. As prices stabilize, this volume base will serve as the foundation for earnings recovery.

3. Strategic Pivot: BC Technology as the Core Competitive Moat

The most compelling aspect of Longi’s current strategy is its aggressive transition to Back Contact (BC) technology. Unlike the homogeneous competition in PERC and TOPCon sectors, BC technology offers higher efficiency and aesthetic advantages, allowing for product differentiation and premium pricing. Longi is not just participating in this shift; it is leading it.

HPBC 2.0 Ramp-Up:
* Capacity Expansion: In 2025H1, Longi’s high-value HPBC 2.0 advanced capacity steadily ramped up. The Company expects that by the end of 2025, the proportion of HPBC 2.0 high-efficiency battery capacity will exceed 60% of its total capacity. This rapid conversion of legacy capacity to BC signifies a decisive strategic bet.
* Performance Metrics: The mass-produced HPBC 2.0 modules have achieved a conversion efficiency of 24.8%. This is significantly higher than mainstream TOPCon modules, providing a clear technical advantage.
* Global Reach: Approximately 4 GW of HPBC products were shipped in H1 2025. These products are not confined to domestic markets but are畅销 (best-sellers) in over 70 countries and regions, including China, Europe, Asia-Pacific, Latin America, and the Middle East/Africa. This global diversification reduces reliance on any single market and captures demand in regions willing to pay a premium for efficiency and reliability.

Innovation Leadership: HIBC Technology:
* Technological Breakthrough: Longi has successfully developed and mass-produced HIBC (Heterojunction Interdigitated Back Contact) modules. This technology combines the high-quality passivation of HIT (Heterojunction) with the BC process.
* Record Efficiency: Utilizing the "golden size" dimensions of $2382 \mathrm{~mm} \times 1134 \mathrm{~mm}$, the HIBC modules achieve a power output of 700W+ and an efficiency of 25.9%.
* Industry Significance: This makes it the highest efficiency industrial PV product globally. Such a milestone reinforces Longi’s R&D prowess and sets a new benchmark for the industry. It positions Longi to dominate the high-end distributed rooftop market, where space constraints and aesthetics make efficiency and appearance paramount.

Differentiation Strategy:
By focusing on BC technology, Longi is effectively exiting the low-margin commodity trap. The "differentiated competitive advantage" mentioned in the report is not merely marketing rhetoric; it is backed by measurable efficiency gains and a growing portfolio of high-value shipments. As the industry matures, customers increasingly prioritize Levelized Cost of Electricity (LCOE) over initial module price, favoring high-efficiency products like HPBC and HIBC.

4. Financial Forecast and Valuation Adjustments

Our financial model has been updated to reflect the latest operational data and macroeconomic conditions in the PV sector. While the long-term outlook remains positive, near-term headwinds necessitate a revision of our 2025 estimates.

Earnings Forecast Revision:
* 2025E Revenue: We project full-year revenue of CNY 67.6 billion, a YoY decline of 18.1%. This reflects the continued impact of lower ASPs throughout the year, despite volume growth.
* 2025E Net Profit: We now estimate a net loss attributable to shareholders of -CNY 3.6 billion. This is a downward revision from our previous forecast of -CNY 2.4 billion.
* Reason for Downgrade: The primary drivers for this adjustment are the persistent downward trend in PV industry chain prices and the resulting inventory impairment losses. As prices remain below cost for extended periods, the value of existing inventory must be written down, directly impacting the bottom line.
* 2026E & 2027E Recovery: We maintain our forecasts for a strong recovery in subsequent years.
* 2026E: Revenue of CNY 72.3 billion (+6.8% YoY) and Net Profit of CNY 2.0 billion. This marks the return to profitability.
* 2027E: Revenue of CNY 74.2 billion (+2.7% YoY) and Net Profit of CNY 4.9 billion.

Valuation Analysis:
* Current Valuation: At the current price of CNY 17.40, the stock trades at a P/B ratio of approximately 2.28x for 2025E. Given the temporary losses, P/E multiples are not meaningful for 2025.
* Forward Valuation: Looking ahead to 2026, the implied P/E is 66.1x, which drops to 27.1x in 2027. While a 66x P/E may appear elevated, it must be contextualized within the cyclical nature of the industry. The market is pricing in the inflection point of profitability. As earnings normalize in 2027, the valuation becomes more reasonable.
* EV/EBITDA: The EV/EBITDA multiple improves dramatically from 118.9x in 2025E to 14.5x in 2026E and 9.5x in 2027E, indicating that the enterprise value is supported by future cash flow generation potential once the cycle turns.

Balance Sheet Strength:
Longi maintains a robust balance sheet, which is a critical buffer during this downturn.
* Cash Position: Cash and equivalents stand at CNY 53.2 billion (2024A) and are projected to remain healthy at CNY 45.6 billion in 2025E, despite negative operating cash flows.
* Debt Management: The debt-to-asset ratio is manageable at 58.4% (2025E), down from 59.8% in 2024. The current ratio is strong at 1.58, ensuring sufficient liquidity to meet short-term obligations.
* Asset Quality: The Company is actively managing its asset base, with non-current assets decreasing from CNY 62.8 billion to an estimated CNY 61.1 billion in 2025, suggesting prudent capital expenditure control and potential disposal of obsolete assets.

5. Industry Context: Supply Clearing and Price Stabilization

To understand Longi’s prospects, one must analyze the broader industry dynamics. The PV sector is currently in a phase of supply-side clearing.

• Price Below Cost: For much of 2024 and early 2025, module and wafer prices have traded below the cash cost of production for many Tier 2 and Tier 3 manufacturers. This is unsustainable and forces weaker players to shut down capacity or exit the market.
• Inventory Impairment: The widespread inventory write-downs seen across the industry (including Longi’s revised forecast) are a necessary painful step to clear out high-cost inventory. Once this inventory is cleared, new production at lower costs (or higher efficiency) will flow through to the P&L.
• Policy Support: There are increasing signs of government and industry association interventions aimed at curbing irrational expansion and promoting healthy competition ("industry self-discipline"). If these measures succeed, the supply-demand imbalance will correct faster than anticipated.
• Demand Resilience: Despite price volatility, global demand for solar energy remains robust, driven by energy transition goals, falling LCOE, and grid parity achievements in many markets. Longi’s global footprint allows it to capture this demand wherever it is strongest.

Risks / Headwinds

While the investment case for Longi is strong, institutional investors must carefully consider the following risks, which could delay the anticipated recovery or impact profitability.

1. Intense Price Competition in the Module Sector

• Risk Description: The PV module market remains highly fragmented and competitive. If competitors, particularly those with state backing or lower cost structures in specific regions, engage in aggressive price cutting to gain market share, it could prolong the period of below-cost pricing.
• Impact: This would further compress gross margins, potentially pushing them below our 3.7% estimate for 2025 and delaying the margin expansion expected in 2026. It could also force Longi to recognize additional inventory impairments.
• Mitigation: Longi’s focus on differentiated BC products helps insulate it from pure price competition in the standard segment. However, if the premium for BC erodes due to widespread adoption by competitors, this moat could narrow.

2. Slower-than-Expected Recovery in Silicon and Module Prices

• Risk Description: Our profitability forecast for 2026 assumes a stabilization and modest recovery in ASPs. If the supply overhang persists longer than expected, or if demand growth slows (e.g., due to trade barriers, grid connection bottlenecks, or macroeconomic slowdowns), prices may remain depressed.
• Impact: Persistent low prices would mean that volume growth does not translate into revenue growth or profit improvement. The "incremental volume without incremental revenue" trend could continue, keeping the Company in a loss-making position for longer.
• Mitigation: Longi’s vertical integration provides some flexibility to shift margins between segments, but it cannot fully offset systemic price declines.

3. Insufficient Industry Self-Discipline

• Risk Description: The report highlights "industry self-discipline" as a factor. This refers to the ability of major players and industry bodies to agree on capacity controls and rational pricing. If new capacity continues to come online despite losses, or if local governments continue to subsidize inefficient producers, the supply clearing process will be delayed.
• Impact: This would extend the duration of the industry winter, increasing cash burn and potentially leading to further balance sheet stress for all players, including Longi.
• Mitigation: Longi’s strong cash position allows it to outlast weaker competitors. However, prolonged distress can still impact investor sentiment and valuation multiples.

4. BC Product Ramp-Up and Market Acceptance Risks

• Risk Description: Longi’s strategy hinges on the successful mass production and market acceptance of HPBC and HIBC products. There are execution risks in scaling up new technology, including yield rates, production costs, and supply chain readiness. Additionally, if the market does not value the efficiency premium sufficiently, or if competing technologies (such as advanced TOPCon or perovskite tandems) gain traction faster, Longi’s differentiation advantage could be compromised.
• Impact: Failure to achieve the targeted 60% BC capacity mix or lower-than-expected sales premiums would result in missed revenue and margin targets.
• Mitigation: Longi has a proven track record in R&D and manufacturing scale-up. The early success of HPBC 2.0 shipments (4GW in H1) is a positive indicator. However, continuous monitoring of yield rates and customer feedback is essential.

5. Geopolitical and Trade Policy Risks

• Risk Description: As a global exporter, Longi is exposed to trade barriers, tariffs, and regulatory changes in key markets such as the US, Europe, and India. Recent trends show increasing protectionism in the renewable energy sector.
• Impact: Tariffs could reduce the competitiveness of Longi’s products in high-margin markets, forcing the Company to redirect sales to lower-margin regions or invest in localized manufacturing (which carries its own capital and operational risks).
• Mitigation: Longi’s diversified global presence (70+ countries) helps mitigate reliance on any single market. The Company may need to accelerate overseas capacity deployment to navigate trade barriers.

Rating / Sector Outlook

Investment Rating: BUY (Maintained)

We maintain our BUY rating on Longi Green Energy. This rating reflects our conviction that the Company is well-positioned to emerge from the current industry downturn as a stronger, more profitable entity. The key reasons for this stance are:

1. Leadership in Next-Gen Technology: Longi is not just surviving the cycle; it is defining the next phase of PV technology with its BC roadmap. The 25.9% efficiency record and 60% BC capacity target by end-2025 provide a clear path to margin expansion.
2. Financial Resilience: With a strong cash position and manageable debt levels, Longi has the endurance to withstand the current price war and consolidate market share as weaker players exit.
3. Valuation Opportunity: The current stock price reflects the near-term pain (2025 losses) but arguably underprices the magnitude of the recovery in 2026 and 2027. For long-term investors, the current dip offers an attractive entry point before the profitability inflection becomes widely recognized.
4. Sequential Improvement: The Q2 2025 data shows clear signs of stabilization, with revenue rising QoQ and losses narrowing. This trend is likely to continue as the BC mix increases and industry supply tightens.

Sector Outlook: Cautiously Optimistic for 2H 2025 and Beyond

The broader PV sector is expected to remain volatile in the short term but shows signs of bottoming out.
* Short Term (2H 2025): Continued pressure on margins as inventory clearing completes. However, the pace of loss-making should decelerate. Industry consolidation will accelerate.
* Medium Term (2026-2027): We anticipate a supply-demand rebalancing. As inefficient capacity exits and demand continues to grow, prices should stabilize above cash costs. Companies with technological differentiation (like Longi with BC) will enjoy superior margins.
* Long Term: The global energy transition remains intact. Solar PV will continue to be a cornerstone of renewable energy deployment. The winners will be those who can deliver the lowest LCOE through high efficiency and reliable manufacturing – areas where Longi excels.

Investment View

Core Investment Logic

1. The "BC Revolution" is Real and Profitable
Investors should view Longi not merely as a commodity manufacturer but as a technology-driven premium player. The shift to BC is not a marginal improvement; it is a structural change in the product landscape. By targeting the high-end distributed market, Longi is accessing a segment less sensitive to raw module price fluctuations and more sensitive to performance and aesthetics. The 4GW shipment of HPBC in H1 2025 is the proof of concept; the scaling to 60% capacity is the growth engine. The HIBC 25.9% efficiency record serves as a powerful marketing tool and a barrier to entry for competitors.

2. Buying the Bottom of the Cycle
Cyclical industries reward investors who buy when headlines are negative but fundamentals are stabilizing. The PV sector is currently in the "pain phase" of the cycle, characterized by losses and impairments. However, Longi’s Q2 sequential improvement signals that the bottom is near. The revised 2025 loss estimate of CNY 3.6 billion is likely the peak of the pain. The projected swing to CNY 2.0 billion profit in 2026 represents a significant earnings inflection. Historical analysis of PV cycles suggests that stock prices often begin to recover before profits fully materialize, as investors anticipate the turnaround.

3. Balance Sheet as a Strategic Asset
In a capital-intensive industry undergoing consolidation, cash is king. Longi’s ability to maintain a strong liquidity position allows it to:
* Continue R&D investment while competitors cut back.
* Seize market share opportunities as competitors falter.
* Navigate trade barriers by potentially investing in overseas manufacturing if needed.
* Weather the storm without dilutive equity raises or distress financing.

Strategic Recommendations for Institutional Investors

• Accumulate on Weakness: Given the volatility, investors may consider building positions during market dips. The long-term thesis remains intact despite short-term noise.
• Monitor BC Metrics: Key performance indicators to watch in upcoming quarterly reports include:
  • % of total shipments comprised of BC products.
  • Average Selling Price (ASP) premium of BC modules vs. standard TOPCon/PERC.
  • Gross margin trends in the module segment specifically.
• Track Industry Supply Data: Keep an eye on industry-wide capacity utilization rates and inventory levels. A sustained drop in industry inventory would be a strong leading indicator for price stabilization.
• Long-Term Horizon: This investment is best suited for investors with a 2-3 year horizon, allowing time for the industry cycle to turn and Longi’s BC strategy to fully mature.

Conclusion

Longi Green Energy is navigating one of the most challenging periods in the history of the PV industry with strategic clarity and operational discipline. The 2025H1 results, while showing a loss, demonstrate significant progress in loss reduction and a successful pivot to high-value BC technology. The Company’s ability to innovate (HIBC 25.9% efficiency) and execute (4GW BC shipments, 60% capacity target) sets it apart from peers.

While near-term risks related to price competition and inventory impairments persist, the medium-to-long-term outlook is compelling. The expected return to profitability in 2026, driven by industry consolidation and BC margin expansion, offers a clear path to value creation. We believe the market has overly penalized the stock for near-term headwinds, creating an attractive risk-reward opportunity. Therefore, we reiterate our BUY rating, confident that Longi will emerge from this winter stronger and more dominant in the high-efficiency solar market.
