Executive Summary

Trina Solar Co., Ltd. ("Trina" or the "Company"), a leading global integrated photovoltaic (PV) solutions provider, released its third-quarter financial results for 2025 in October. The report highlights a critical inflection point in the Company’s operational trajectory: while top-line revenue remains under pressure due to broader industry headwinds, profitability metrics are showing signs of sequential stabilization, and strategic diversification into energy storage is gaining significant momentum.

In the first three quarters of 2025 (25Q1-Q3), Trina reported total revenue of CNY 49.97 billion, representing a year-over-year (YoY) decline of 20.87%. The Company recorded a net loss attributable to shareholders of CNY 4.201 billion and a扣非 (deducting non-recurring items) net loss of CNY 4.315 billion. However, a granular look at the third quarter (25Q3) reveals encouraging trends. Q3 revenue stood at CNY 18.914 billion, down 6.27% YoY but up 13.12% quarter-over-quarter (QoQ). More importantly, the net loss narrowed significantly to CNY 1.283 billion (CNY 1.359 billion on a non-GAAP basis), indicating that the worst of the margin compression may be behind the Company.

Our analysis suggests that Trina is successfully navigating the current industry downturn through two primary levers: rigorous cost control and technological leadership in N-type TOPCon modules. Furthermore, the rapid expansion of its energy storage system (ESS) business, particularly in overseas markets, provides a robust second growth curve that is expected to support medium-to-long-term earnings recovery.

We maintain our OUTPERFORM rating on Trina Solar. We project the Company to return to profitability in 2026, with estimated net profits of CNY 1.917 billion in 2026E and CNY 3.076 billion in 2027E. Based on the closing price of CNY 20.37 on October 31, 2025, the stock trades at an implied forward P/E of 23x for 2026E and 14x for 2027E. Given the Company’s dominant market position in high-efficiency modules and the accelerating contribution from its high-margin storage business, we believe the current valuation offers an attractive entry point for long-term institutional investors anticipating the industry’s supply-side clearance and demand recovery.

Key Takeaways

1. Financial Performance: Sequential Improvement Amidst Industry Headwinds

The core narrative of Trina’s 2025 performance is one of resilience in the face of severe industry-wide pricing pressure. While the full-year outlook remains challenging, the sequential improvement in Q3 demonstrates management’s ability to mitigate downside risks.

Revenue Trends: Stabilization in Sight

• Cumulative Performance (25Q1-Q3): Total revenue reached CNY 49.97 billion, a YoY decrease of 20.87%. This decline reflects the broader contraction in the PV sector, driven by falling module prices and intense competition.
• Quarterly Dynamics (25Q3): Q3 revenue was CNY 18.914 billion. While still down 6.27% YoY, the 13.12% QoQ increase is a vital signal. It suggests that shipment volumes are stabilizing or growing, even if average selling prices (ASPs) remain depressed. This sequential growth indicates that the Company is maintaining its market share and potentially benefiting from seasonal demand upticks in key overseas markets.

Profitability: Loss Narrowing and Margin Stabilization

• Net Loss Analysis: The Company reported a net loss attributable to shareholders of CNY 1.283 billion in Q3, compared to wider losses in previous quarters. The non-GAAP net loss was CNY 1.359 billion. The narrowing of the loss quarter-over-quarter is a testament to improved operational efficiency and cost management.
• Margin Trajectory:
  • Gross Margin: Q3 gross margin stood at 4.49%, a slight but meaningful improvement of +0.04 percentage points (ppts) QoQ. In an environment where many peers are struggling with negative or single-digit margins, maintaining a positive gross margin is a competitive advantage.
  • Net Margin: The net margin was -6.83%, which represents a substantial improvement of +2.63 ppts QoQ. This significant jump in net margin, despite a modest rise in gross margin, points strongly to effective operating expense control and potentially reduced asset impairment charges compared to prior periods.

Expense Management: Disciplined Cost Control

Trina’s ability to improve net margins despite flat gross margins is largely attributed to stringent expense management. The breakdown of operating expenses in Q3 reveals a concerted effort to optimize the cost structure:

Note: Excluding the rise in financial expenses, all other major operating expense ratios showed marked improvement. The total reduction in selling, administrative, and R&D expenses by over 1.2 ppts collectively provided a crucial buffer to the bottom line.

2. Technological Leadership:至尊 (Vertex) N-Type TOPCon Dominance

In the highly commoditized PV module market, technological differentiation is the primary driver of premium pricing and market share retention. Trina Solar continues to lead the industry in N-type TOPCon (Tunnel Oxide Passivated Contact) technology, reinforcing its brand value and product competitiveness.

Record-Breaking Efficiency and Power Output

According to the October 2025 mass-production efficiency rankings published by TaiyangNews, Trina’s Vertex N-type modules achieved a mass-production delivery power of 720W. This achievement places Trina at the forefront of the TOPCon module power output records.

• Significance of 720W: In utility-scale projects, higher wattage modules directly translate to lower Balance of System (BOS) costs, including reduced land usage, fewer mounting structures, and lower installation labor costs. This makes Trina’s products highly attractive to developers focused on Levelized Cost of Energy (LCOE) reduction, allowing Trina to command a slight premium or secure larger contract volumes compared to lower-wattage competitors.

Future Roadmap: i-TOPCon Ultra Technology

Looking ahead, Trina is not resting on its current laurels. The Company is preparing to launch the next generation of its Vertex N-type series based on its proprietary i-TOPCon Ultra technology.
* Projected Milestone: Mass production power output for large-format modules is expected to exceed 740W.
* Strategic Implication: This continuous innovation cycle ensures that Trina remains at the "leading edge" of the technology S-curve. As the industry transitions fully from P-type PERC to N-type TOPCon, and eventually towards tandem technologies, Trina’s aggressive R&D roadmap positions it to capture the highest-value segment of the market.

Supply-Side Clearance and Market Share Gains

The Chinese PV industry is currently undergoing a painful but necessary phase of supply-side clearance. Government policies and market forces are accelerating the exit of outdated, inefficient产能 (production capacity), particularly older P-type lines and less efficient N-type manufacturers.
* Consolidation Benefit: As weaker players exit the market, the supply-demand balance is expected to improve. Trina, with its superior technology and cost structure, is well-positioned to gain market share from these exiting competitors.
* Premiumization: The market is increasingly bifurcating between standard commodity modules and high-efficiency premium modules. Trina’s focus on the latter insulates it from the fiercest price wars in the low-end segment.

3. Second Growth Curve: Energy Storage Systems (ESS) Acceleration

While the PV module business faces cyclical headwinds, Trina’s Energy Storage System (ESS) business is emerging as a powerful counter-cyclical growth engine. The Company is strategically leveraging its global channel network and brand reputation to expand its footprint in the rapidly growing global storage market.

Order Book Momentum

Since September 2025, Trina has announced a series of significant contracts, securing multiple GWh-level orders for its storage systems. This surge in order intake validates the market’s acceptance of Trina’s storage solutions and highlights the scalability of this business unit.

Overseas Market Penetration

A key differentiator for Trina’s storage business is its strong international presence.
* 2025 Mix: Overseas orders already account for 60% of the total storage business volume in 2025.
* 2026 Outlook: The Company expects overseas orders to maintain a high proportion, exceeding 50% in 2026.
* Strategic Advantage: International markets, particularly in Europe, North America, and emerging markets in the Middle East and Asia-Pacific, generally offer higher margins and more stable demand profiles compared to the domestic Chinese market. By focusing on overseas clients, Trina can achieve better profitability in its storage segment.

Contribution to Long-Term Earnings

The storage business is not just a revenue add-on; it is becoming a structural pillar of Trina’s earnings model.
* High Growth Potential: The global energy transition requires massive grid flexibility, driving exponential demand for battery energy storage systems (BESS). Trina’s integrated approach—offering both PV modules and storage solutions—allows for bundled offerings, enhancing customer stickiness and cross-selling opportunities.
* Margin Support: As the storage business scales, its contribution to the overall gross profit mix will increase. Given the higher value-add in system integration compared to pure module manufacturing, this shift should structurally improve Trina’s blended margins over the medium term.

4. Valuation and Investment Thesis

Financial Forecast (2025-2027E)

Based on our analysis of current order books, pricing trends, and cost structures, we have updated our financial projections for Trina Solar.

Source: Minsheng Securities Research Institute Estimates; Price as of Oct 31, 2025.

Interpretation of Forecasts

1. 2025E: The Bottoming Year: We expect 2025 to be the trough year for Trina’s profitability, with a projected net loss of CNY 4.4 billion. This reflects the full impact of low module prices and inventory write-downs. However, the sequential improvement seen in Q3 suggests that the second half of 2025 will be stronger than the first.
2. 2026E: The Turnaround Year: We forecast a return to profitability with a net profit of CNY 1.92 billion. This turnaround is driven by:
   • Stabilization of module prices as supply clears.
   • Volume growth from new high-efficiency TOPCon capacity.
   • Significant profit contribution from the scaling ESS business.
3. 2027E: Sustainable Growth: Net profit is expected to grow by 60.4% to CNY 3.08 billion, reflecting a matured storage business and a healthier PV market environment.

Valuation Assessment

At the current price of CNY 20.37, Trina trades at:
* 2026E P/E: ~23x
* 2027E P/E: ~14x
* 2025E P/B: ~2.0x

For a leading technology manufacturer in the renewable energy sector, a forward P/E of 14-23x is reasonable, especially considering the high growth potential of the storage segment and the cyclical recovery of the PV industry. The P/B ratio of 2.0x in 2025E reflects the temporary depression in earnings; as profits recover, the P/B is expected to compress to more attractive levels (1.7x in 2027E).

Compared to historical valuations and peer averages, Trina appears undervalued relative to its long-term earnings power. The market is currently pricing in prolonged distress, but our analysis suggests a faster recovery trajectory, particularly driven by the non-consensus strength in the storage business.

Risks / Headwinds

While the investment thesis is compelling, institutional investors must carefully weigh the following risks, which could materially impact Trina’s financial performance and stock price.

1. Raw Material Price Volatility

• Polysilicon and Wafer Prices: Although polysilicon prices have dropped significantly, further volatility can impact inventory valuation and gross margins. If raw material prices rebound sharply while module ASPs remain stagnant, margins could be squeezed again. Conversely, rapid declines can lead to inventory write-downs, as seen in previous quarters.
• Battery Materials: For the ESS business, the prices of lithium carbonate and other battery components are critical. Fluctuations in these inputs can affect the profitability of storage system integration.

2. Downstream Industry Sentiment and Demand Fluctuations

• Project Delays: Global PV and storage project installations are sensitive to macroeconomic conditions, interest rates, and policy changes. A slowdown in downstream demand in key markets (e.g., Europe, US, China) would directly impact Trina’s shipment volumes.
• Grid Connection Bottlenecks: In many markets, the pace of new renewable energy installations is constrained by grid infrastructure limitations. Delays in grid approvals can push revenue recognition into future periods.

3. Intensified Industry Competition

• Price Wars: The PV industry is characterized by high fixed costs and homogeneous products, leading to fierce price competition. If competitors engage in aggressive pricing to clear inventory or gain market share, Trina may be forced to lower prices, eroding margins.
• Technology Disruption: While Trina leads in TOPCon, the industry is constantly evolving. Rapid advancements in HJT (Heterojunction) or Perovskite tandem cells by competitors could challenge Trina’s technological edge if its i-TOPCon Ultra roadmap faces delays or fails to deliver expected efficiencies.

4. Asset Impairment Risks

• Inventory and Fixed Assets: Given the rapid technological iteration in the PV sector, older production equipment and inventory can become obsolete quickly. Trina may need to continue recognizing asset impairment losses if it decides to retire older P-type capacity or if inventory values drop below cost. The forecast assumes impairments of CNY 600 million in 2025E, CNY 500 million in 2026E, and CNY 400 million in 2027E; any deviation above these estimates would negatively impact net profit.

5. International Trade and Geopolitical Risks

• Tariffs and Trade Barriers: Trina has significant overseas exposure (60% of storage orders, substantial module exports). Trade policies such as the U.S. Inflation Reduction Act (IRA), European Union anti-subsidy investigations, or potential new tariffs in other markets could restrict access or increase costs.
• Supply Chain Decoupling: Geopolitical tensions may force customers to prefer non-Chinese suppliers, potentially limiting Trina’s addressable market in certain regions despite its competitive advantages.

6. Exchange Rate Fluctuations

• Financial Expenses: As noted in the Q3 results, financial expenses rose due to exchange rate movements. Since a large portion of Trina’s revenue is denominated in foreign currencies (USD, EUR) while many costs are in CNY, significant appreciation of the CNY could hurt revenue translation and competitiveness, while depreciation could increase the cost of imported materials or debt servicing.

Rating / Sector Outlook

Sector Outlook: From Capacity Expansion to Quality Consolidation

The global photovoltaic and energy storage sector is transitioning from a phase of unchecked capacity expansion to one of quality-driven consolidation.

1. Supply-Side Reform: Chinese regulatory authorities are increasingly emphasizing high-quality development, discouraging low-level redundant construction. This policy shift, combined with market-driven bankruptcies of inefficient players, is expected to accelerate the clearance of backward capacity. This is a bullish signal for industry leaders like Trina Solar, who possess superior technology, scale, and financial resilience.
2. Demand Resilience: Despite short-term fluctuations, the long-term global demand for renewable energy remains robust, driven by carbon neutrality goals, energy security concerns, and the declining LCOE of solar plus storage.
3. Storage as a Key Driver: The integration of storage with solar is becoming the norm. Companies that can offer integrated "Solar + Storage" solutions are gaining a competitive moat. Trina’s early and aggressive move into the ESS market positions it favorably in this evolving landscape.

Rating Justification: OUTPERFORM

We maintain our OUTPERFORM rating on Trina Solar (688599.SH) based on the following convictions:

1. Bottoming Out of Earnings: The sequential narrowing of losses in Q3 2025 signals that the Company has navigated the most difficult period of margin compression. The worst is likely behind us.
2. Technological Moat: Leadership in N-type TOPCon efficiency (720W+) and the upcoming i-TOPCon Ultra platform ensures Trina remains a preferred supplier for high-value projects, protecting its market share and pricing power.
3. Diversification Success: The energy storage business is no longer a speculative venture but a tangible growth driver with a strong order book and high overseas exposure. This diversification reduces reliance on the cyclical module market and enhances overall profitability.
4. Attractive Valuation: Trading at 14x 2027E earnings, the stock offers a compelling risk-reward profile for investors willing to look through the short-term noise of 2025 losses. The market has not fully priced in the magnitude of the 2026-2027 earnings recovery.

Investment View

Strategic Positioning for Institutional Investors

For institutional investors, Trina Solar represents a classic "Turnaround Play" within the renewable energy sector. The investment case rests on the convergence of cyclical recovery and structural growth.

1. The Cyclical Argument: Buying the Dip

The PV industry is deeply cyclical. Historically, the best time to invest in leading manufacturers is when industry-wide losses are peak, capacity is being cleared, and valuations are depressed. Trina’s 2025 losses reflect this trough. By maintaining a strong balance sheet and continuing R&D investment during the downturn, Trina is positioning itself to capture disproportionate upside when the cycle turns. The projected return to profitability in 2026 is not just a recovery but a re-rating opportunity.

2. The Structural Argument: Storage Integration

The standalone PV module business is maturing, but the integrated energy solution market is in its early growth phase. Trina’s ability to cross-sell storage systems to its existing global module customer base provides a unique competitive advantage.
* Customer Stickiness: Developers prefer single-point accountability for both generation and storage. Trina’s integrated offering simplifies procurement and warranty management for clients.
* Margin Expansion: Storage systems typically carry higher margins than commoditized modules. As the mix shifts towards storage, Trina’s blended ROE (Return on Equity) should structurally improve, moving from the current negative territory to a sustainable double-digit level (projected 12.03% ROE in 2027E).

3. Execution Risk Monitoring

Investors should closely monitor the following key performance indicators (KPIs) in upcoming quarterly reports to validate the investment thesis:
* Gross Margin Trend: Confirmation that gross margins remain above 5-6% and show sequential improvement.
* Storage Order Conversion: Tracking the conversion of the reported GWh-level orders into recognized revenue and profit.
* Cash Flow Generation: Operating cash flow turned positive in recent periods (CNY 2.8 billion estimated for 2025E). Sustained positive operating cash flow is critical to fund R&D and reduce leverage without dilutive equity raises.
* Overseas Revenue Mix: Maintenance of a high overseas revenue proportion, which is crucial for margin protection.

Conclusion

Trina Solar is demonstrating remarkable resilience in a challenging market environment. The Q3 2025 results, characterized by narrowing losses and disciplined cost control, confirm that the Company is effectively managing the downturn. Simultaneously, its technological leadership in N-type TOPCon modules and the rapid ascent of its energy storage business provide clear pathways for future growth.

While near-term risks related to trade policies and industry competition persist, the long-term fundamentals remain intact. The current valuation does not fully reflect the potential earnings power of the Company in the 2026-2027 period. Therefore, we view Trina Solar as a compelling investment opportunity for institutional portfolios seeking exposure to the global energy transition, with a specific focus on high-quality, diversified leaders capable of weathering cyclical storms.

We recommend accumulating positions on weakness, with a target horizon of 12-18 months to capture the anticipated earnings recovery and multiple expansion.

Appendix: Detailed Financial Analysis & Data Tables

A. Income Statement Analysis (Historical & Forecast)

The following table details the projected recovery in Trina’s income statement, highlighting the transition from loss to profit.

Key Observation: The significant jump in Gross Profit from 2025E to 2026E (CNY 5.7bn to CNY 13.9bn) is the primary driver of the turnaround. This assumes a normalization of module pricing and a higher-margin product mix driven by TOPCon and Storage.

B. Balance Sheet Health & Liquidity

Trina maintains a robust balance sheet, essential for surviving industry downturns and funding capital-intensive expansion.

Liquidity Ratios:
* Current Ratio: Remains stable around 1.20-1.24x, indicating adequate short-term liquidity.
* Debt-to-Asset Ratio: Increases slightly from 73.98% in 2024 to 78.10% in 2026E, reflecting leverage used to fund working capital and expansion during the downturn. This is manageable given the Company’s asset quality and cash flow generation potential.

C. Cash Flow Dynamics

Cash flow analysis reveals the Company’s ability to self-fund operations despite accounting losses.

Key Insight: Positive operating cash flow in 2025E (CNY 2.8 billion) despite a net loss of CNY 4.4 billion is driven by significant depreciation and amortization (CNY 6.2 billion) and working capital management. This cash generation capability is vital for sustaining R&D and CapEx without excessive external financing. The reduction in CapEx from 2024A to 2025E/2026E indicates a shift from aggressive expansion to optimized capacity utilization.

D. Key Financial Ratios & Valuation Metrics

Valuation Note: The EV/EBITDA multiple compresses significantly from ~20x in 2025E to ~6x in 2027E, reflecting the normalization of earnings. A 6x EV/EBITDA is attractive for a growth-oriented tech-manufacturing firm, suggesting potential undervaluation if the 2027 earnings targets are met.
