Executive Summary

Tongwei Co., Ltd. ("Tongwei" or the "Company"), a global leader in high-purity crystalline silicon and solar cells, has demonstrated clear signs of an operational inflection point in the third quarter of 2025 (3Q25). After enduring a prolonged period of industry-wide margin compression and intense price competition—often referred to as "involution"—the photovoltaic (PV) sector is witnessing a structural shift towards rational pricing. This report analyzes Tongwei’s 3Q25 financial performance, dissecting the drivers behind the narrowing losses, the impact of rising silicon prices, and the dynamics within its cell and module segments.

In 3Q25, Tongwei reported a net loss attributable to shareholders of CNY 315 million, representing a significant year-over-year (YoY) improvement of 62.69% and a quarter-over-quarter (QoQ) improvement of 86.68%. This turnaround was primarily driven by two factors: (1) a substantial rebound in polysilicon prices following industry-wide initiatives to curb irrational price wars starting in July 2025, and (2) effective cost management during the Sichuan region’s hydropower-rich season. While the downstream cell and module segments faced margin pressure due to weaker price transmission mechanisms, the Company’s strategic positioning in advanced N-type technologies remains a competitive moat.

We maintain our "Accumulate" rating on Tongwei. Our investment thesis is anchored in the expectation that the worst of the industry cycle has passed. We project the Company to return to profitability in 2026, with estimated net profits of CNY 1.4 billion in 2026 and CNY 2.8 billion in 2027. The current valuation reflects the market’s anticipation of this recovery, with forward P/E ratios compressing to attractive levels as earnings normalize. Key risks remain centered on the sustainability of global PV installation demand and the potential for renewed price volatility in the upstream supply chain.

Key Takeaways

1. Financial Performance: Losses Narrow Significantly in 3Q25, Signaling Cycle Bottom

Tongwei’s financial results for the first nine months of 2025 (9M25) reflect the lingering effects of the industry downturn, but the trajectory in 3Q25 offers compelling evidence of stabilization.

• 9M25 Overview: The Company generated total revenue of CNY 64.6 billion, a decline of 5.38% YoY. Net profit attributable to shareholders stood at a loss of CNY 5.27 billion, a deterioration of 32.64% YoY. This cumulative loss is consistent with the broader industry context where prices for key PV materials fell below cash costs for much of the first half of the year.
• 3Q25 Breakdown:
  • Revenue: CNY 24.09 billion, down 1.57% YoY and 1.97% QoQ. The slight sequential decline is attributed to seasonal adjustments and inventory management rather than demand destruction.
  • Net Profit: A loss of CNY 315 million. Crucially, this represents a 62.69% YoY improvement and an 86.68% QoQ improvement.
  • Non-Recurring Items: In 3Q25, the Company reversed asset impairment losses by CNY 247 million and credit impairment losses by CNY 12 million. These reversals contributed positively to the bottom line, indicating that previous provisions were conservative and that asset quality is stabilizing.

The sharp reduction in quarterly losses suggests that the Company has successfully navigated the trough of the cycle. The ability to limit losses despite lower overall revenue volumes underscores the effectiveness of its cost-control measures and the beneficial impact of rising average selling prices (ASPs) in the silicon segment.

2. Polysilicon Segment: The Primary Driver of Recovery

The polysilicon business, Tongwei’s core profit center historically, has been the primary beneficiary of the industry’s shift away from destructive competition. The term "anti-involution" (fan neijuan) refers to coordinated efforts by major producers to align production with demand and restore prices to sustainable levels above full cash costs.

A. Price Rebound Dynamics

Starting in July 2025, polysilicon prices began a steady upward trajectory. According to data from the Silicon Industry Branch, the average price of N-type recycled material (a key benchmark for high-efficiency modules) surged:
* July 2, 2025: CNY 34,700/ton
* September 24, 2025: CNY 53,200/ton

This represents a ~53% increase in ASPs within a single quarter. This price recovery was not merely a speculative spike but a structural correction driven by:
1. Supply Discipline: Major producers, including Tongwei, adjusted operating rates to prevent oversupply.
2. Cost Support: Prices rose to meet the full cost line, ensuring that leading producers could cover all-in costs including depreciation and financial expenses.

B. Cost Advantage Amplification

While prices rose, Tongwei’s production costs remained stable or declined slightly, widening the margin recovery.
* Hydropower Seasonality: The third quarter coincides with the abundant water season in Sichuan province, where Tongwei has significant production capacity. Hydropower is significantly cheaper than thermal power, reducing electricity costs—a major component of polysilicon production expenses.
* Operational Efficiency: The Company maintained stable operating rates, allowing for better absorption of fixed costs.
* Result: The combination of rising ASPs (+53%) and stable/declining unit costs led to a dramatic narrowing of per-ton losses in the silicon segment. In previous quarters, silicon sales were a drag on earnings; in 3Q25, they became a neutral-to-positive contributor relative to the deep losses seen in 1H25.

C. Outlook for 4Q25

Looking ahead to the fourth quarter, we expect silicon prices and unit profitability to remain relatively stable. While there is no strong immediate catalyst for further aggressive price hikes, the floor has been established. The industry is unlikely to revert to sub-cost pricing given the renewed focus on healthy margins among top-tier players. Therefore, 4Q25 should see continued modest profitability or break-even performance in the silicon segment, providing a stable base for the Company’s overall financials.

3. Cell and Module Segment: Mixed Performance Amidst Technology Leadership

While the upstream silicon business recovered, the downstream cell and module segments faced headwinds in 3Q25. The transmission of upstream price increases to downstream products was uneven, reflecting different supply-demand dynamics in each tier of the value chain.

A. Price Transmission Analysis

• Cells: TOPCon cell prices increased by 39% in 3Q25.
  • July 2, 2025: CNY 0.23/W
  • September 25, 2025: CNY 0.32/W
• Modules: N-type module prices increased by only 1% in 3Q25.
  • July 2, 2025: CNY 0.68/W
  • September 25, 2025: CNY 0.69/W

Interpretation: The disparity between cell and module price movements highlights the competitive intensity in the module assembly market. Module manufacturers, facing stiff competition and elastic demand from project developers, were unable to fully pass on the 39% increase in cell costs. This squeezed margins for integrated players like Tongwei who operate in both segments. However, Tongwei’s strong position in the cell market allows it to capture some of this value, even if module margins are compressed.

B. Volume Dynamics

Shipment volumes for cells and modules decreased in 3Q25 compared to the first half. This decline is largely attributed to the "rush installation" effect observed in 1H25, where developers accelerated projects to meet earlier grid-connection targets or subsidy deadlines. The subsequent normalization of demand in 3Q25 led to a temporary dip in shipments. Despite this volume contraction, the Company’s focus on high-efficiency N-type TOPCon technology ensures that its product mix remains premium, supporting higher average realization prices compared to competitors stuck with older P-type technologies.

C. Strategic Positioning

Tongwei’s technological leadership in N-type cells remains a key differentiator. As the industry transitions fully to N-type standards, Tongwei’s early investment in TOPCon capacity positions it well to capture market share as older capacities are phased out. The slight pressure on module margins is viewed as a short-term tactical issue rather than a strategic weakness, given the Company’s vertical integration and cost advantages in cell production.

4. Financial Forecast and Valuation

Based on the 3Q25 performance and our assumptions regarding industry trends, we have updated our financial forecasts for Tongwei for the years 2025 through 2027.

Revenue and Profit Projections

Analysis of Forecasts:
* 2025E: We anticipate a full-year net loss of CNY 5.5 billion. This is an improvement over the 2024 loss of CNY 7.0 billion, driven by the 3Q25 recovery and expected stability in 4Q25. Revenue is projected to decline by 32.3% YoY, reflecting the lower average selling prices throughout most of the year compared to the peak cycles of the past.
* 2026E: This is the pivotal year for Tongwei’s turnaround. We forecast a return to profitability with a net profit of CNY 1.4 billion. This assumes that silicon prices remain above the full cost line and that module margins stabilize as the industry consolidates. Revenue growth of 10.8% is expected as volumes expand to meet global demand growth.
* 2027E: Continued growth is projected, with net profit reaching CNY 2.8 billion (+93.3% YoY). This reflects the maturation of N-type technology adoption and potential expansion into new markets or adjacent value chains. Gross margins are expected to stabilize around 10%, a healthy level for a mature manufacturing industry.

Valuation Metrics

Valuation Commentary:
* P/E Ratio: The forward P/E for 2026 is approximately 85x, which may appear high in absolute terms. However, this is typical for cyclical companies emerging from a loss-making trough, where the denominator (earnings) is small but growing rapidly. By 2027, the P/E compresses to ~44x, reflecting more normalized earnings power. Investors should focus on the direction of earnings growth rather than static multiples in this transition phase.
* EV/EBITDA: This metric provides a clearer picture of operational cash flow generation independent of capital structure and depreciation policies. The drop from 52.36x in 2024 to 11.99x in 2026 indicates a significant improvement in underlying operational profitability. An EV/EBITDA of ~12x is reasonable for a leading industrial manufacturer with stable cash flows.
* P/B Ratio: The Price-to-Book ratio remains elevated at 2.85x for 2025E, reflecting the market’s willingness to pay a premium for Tongwei’s asset quality and market leadership. As retained earnings grow in 2026-2027, the book value will increase, naturally lowering the P/B multiple to more standard levels (~2.6x).

Risks / Headwinds

While the outlook is improving, investors must remain cognizant of several key risks that could derail the recovery thesis.

1. Global PV Installation Demand Miss

The core assumption underpinning our revenue forecasts is steady growth in global solar installations. However, demand is subject to macroeconomic and policy variables:
* Interest Rates: High interest rates in key markets (Europe, US) can increase the cost of capital for utility-scale projects, delaying or canceling installations.
* Policy Shifts: Changes in subsidy schemes, trade tariffs (e.g., US Section 201/301 tariffs, EU anti-subsidy investigations), or local content requirements can disrupt supply chains and reduce demand for Chinese exports.
* Grid Constraints: In many mature markets, grid congestion is becoming a bottleneck for new solar connections, potentially capping near-term demand growth.

If global installations grow slower than expected, the supply-demand balance in polysilicon and modules could tilt back towards oversupply, pressuring prices and margins.

2. Silicon Price Repair Below Expectations

Our thesis relies on the sustainability of the "anti-involution" price discipline. There is a risk that:
* Cheating on Quotas: Some producers might secretly increase operating rates to capture market share, undermining the collective effort to stabilize prices.
* New Capacity Ramp-up: If previously delayed capacity comes online faster than anticipated, it could flood the market.
* Technological Disruption: Emergence of new silicon production technologies that drastically lower costs for new entrants could reset the price floor lower.

If silicon prices fail to stay above the full cost line, Tongwei’s profitability will remain under pressure, delaying the expected return to profit in 2026.

3. Asset Impairment Risks

The PV industry is characterized by rapid technological iteration. The shift from P-type to N-type technology has rendered significant amounts of older capacity obsolete.
* Further Write-downs: While Tongwei reversed some impairments in 3Q25, there is a risk of further large-scale asset write-downs if older facilities are deemed economically unviable.
* Inventory Valuation: Rapid price fluctuations can lead to inventory write-downs if the market price falls below the cost of goods sold.

Unexpectedly large impairments would directly hit the bottom line, potentially turning projected profits into losses or deepening existing losses.

4. Competition in Downstream Segments

The module segment remains highly fragmented and competitive. Even with Tongwei’s technological edge, margin expansion in this segment is challenging. Competitors may engage in aggressive pricing to maintain volume, limiting the upside potential for Tongwei’s integrated model.

Rating / Sector Outlook

Sector Outlook: From "Survival" to "Rational Growth"

The global photovoltaic sector is transitioning from a phase of chaotic expansion and price wars to a period of consolidation and rational pricing. The "anti-involution" measures observed in 3Q25 are not just a temporary tactic but a necessary evolution for the industry’s long-term health.

• Supply Side: Leading players are prioritizing profitability over market share. Capital expenditure is being disciplined, and outdated capacity is being exited. This supply-side reform is critical for restoring return on invested capital (ROIC).
• Demand Side: Long-term demand fundamentals remain robust, driven by global decarbonization goals, energy security concerns, and the declining levelized cost of electricity (LCOE) for solar.
• Technology: The industry is standardizing around N-type TOPCon and HJT technologies. Companies with strong R&D capabilities and scalable N-type production, like Tongwei, are well-positioned to lead the next cycle.

We view the sector as Overweight for long-term investors who can tolerate near-term volatility. The worst of the earnings downturn is likely behind us, and the next 12-24 months should see a gradual restoration of margins and cash flows.

Company Rating: Accumulate (Maintained)

We maintain our Accumulate rating on Tongwei Co., Ltd.

• Rationale: Tongwei is best-in-class in terms of cost structure and scale in the polysilicon segment. Its successful navigation of the 3Q25 inflection point demonstrates resilience. The Company is poised to benefit disproportionately from the industry’s price stabilization due to its low-cost position. While the 2025 full-year result will still be negative, the trajectory towards profitability in 2026 is clear.
• Relative Value: Compared to peers, Tongwei offers a compelling risk-reward profile. Its vertical integration provides a hedge against segment-specific volatility, and its balance sheet, while leveraged, is manageable given its strong operating cash flow potential in a normalized environment.

Investment View

Core Investment Logic

1. Cyclical Turnaround Play: Tongwei represents a classic cyclical turnaround opportunity. The stock has likely priced in the worst-case scenarios of 2024-1H2025. As earnings move from deep losses to breakeven and then to profit, the stock should re-rate upwards. The 3Q25 results confirm that the bottom is in.
2. Cost Leadership Moat: In commodity-like industries such as polysilicon, the lowest-cost producer wins. Tongwei’s access to cheap hydropower in Sichuan and its operational excellence give it a persistent cost advantage. When prices rise, this advantage translates directly into superior margin expansion.
3. Technology Premium: The Company’s early and aggressive investment in N-type TOPCon technology ensures that its product portfolio remains relevant and premium-priced. As the industry phases out P-type capacity, Tongwei’s market share in high-efficiency cells is expected to grow.
4. Financial Leverage to Operating Leverage: With fixed costs largely covered, any incremental increase in revenue or price drops significantly to the bottom line. The projected jump from -CNY 5.5B loss in 2025 to +CNY 1.4B profit in 2026 illustrates this high operating leverage.

Strategic Recommendations for Institutional Investors

• Accumulate on Dips: Given the volatility inherent in the PV sector, investors should consider building positions during market pullbacks. The long-term trend is upward, but short-term noise regarding monthly shipment data or minor price fluctuations may create buying opportunities.
• Monitor 4Q25 Guidance: Pay close attention to management’s commentary on 4Q25 silicon pricing and inventory levels. Confirmation of stable prices will validate the 2026 profit forecast.
• Watch Cash Flow: While net income is important, operating cash flow is the lifeblood of capital-intensive industries. Tongwei’s ability to generate positive operating cash flow (projected CNY 13.4B in 2025E) is a strong indicator of financial health, allowing it to service debt and fund future growth without excessive dilution.

Conclusion

Tongwei Co., Ltd. stands at a pivotal juncture. The 3Q25 results are a beacon of hope in a challenging sector, signaling that the era of destructive price wars is receding. With a robust cost structure, leading technology, and a clear path to profitability in 2026, Tongwei is well-equipped to lead the industry’s recovery. We recommend institutional investors maintain an Accumulate stance, recognizing that the current valuation offers an attractive entry point for the upcoming upcycle.

Appendix: Detailed Financial Analysis

Balance Sheet Strength and Liquidity

Tongwei’s balance sheet reflects the capital-intensive nature of its business but shows signs of strengthening liquidity.

• Cash Position: Cash and cash equivalents are projected to increase from CNY 16.4 billion in 2024 to CNY 27.5 billion in 2025E, and further to CNY 42.7 billion in 2027E. This robust cash pile provides a significant buffer against operational shocks and funds ongoing R&D.
• Debt Management: Total liabilities are expected to decrease from CNY 138.0 billion in 2024 to CNY 127.5 billion in 2026E, before rising slightly to CNY 130.1 billion in 2027E. The reduction in liabilities, coupled with growing equity, will improve the debt-to-equity ratio.
• Asset Quality: Inventory levels are projected to decline from CNY 12.6 billion in 2024 to CNY 4.6 billion in 2026E. This destocking is healthy, reducing the risk of inventory write-downs and freeing up working capital.

Cash Flow Analysis

• Operating Cash Flow (OCF): The surge in OCF to CNY 13.4 billion in 2025E, despite a net loss, is driven by non-cash charges like depreciation (CNY 11.2B) and changes in working capital (destocking). This highlights that the Company’s core operations are generating cash, even if accounting profits are negative due to impairments and depreciation.
• Capital Expenditure (CapEx): Investing cash outflows are decreasing significantly (from -CNY 28.5B in 2024 to -CNY 2.2B in 2025E). This indicates that the heavy investment phase is slowing down, and the Company is shifting from capacity expansion to optimization. Lower CapEx requirements will free up more free cash flow in the future.

Profitability Ratios Trend

• Gross Margin: Expected to recover from a depressed 1.2% in 2025E to 10.0% in 2026E. This 880 basis point expansion is the key driver of the earnings turnaround.
• Net Margin: Will move from -8.9% in 2025E to +2.1% in 2026E.
• ROE (Return on Equity): Projected to turn positive from -12.9% in 2025E to 3.3% in 2026E, and 5.9% in 2027E. While 5.9% is not exceptionally high, it represents a significant improvement from negative returns and indicates efficient use of shareholder capital.

Sensitivity Analysis

To provide a range of outcomes, we consider the following sensitivity scenarios for 2026E Net Profit:

• Base Case: Silicon prices stabilize at CNY 50,000-55,000/ton; Module margins remain thin. Net Profit: CNY 1.4 Billion.
• Bull Case: Silicon prices rise to CNY 60,000+/ton due to stronger demand or stricter supply control; Module margins improve. Net Profit: CNY 2.0 - 2.5 Billion.
• Bear Case: Silicon prices fall back to CNY 40,000/ton due to oversupply; Global installations miss estimates. Net Profit: CNY 0 - 0.5 Billion (Breakeven/Low Profit).

Even in the Bear Case, the Company avoids deep losses, suggesting a higher floor for earnings than in previous cycles.

Final Remarks

Tongwei Co., Ltd. is navigating a complex transition from a period of extreme industry stress to a more balanced and profitable environment. The 3Q25 results are a critical validation of this transition. For institutional investors, the key takeaway is that the downside risk is limited, while the upside potential from earnings normalization is substantial. The Company’s fundamental strengths—cost leadership, technological prowess, and financial resilience—position it as a top-tier candidate for exposure to the recovering solar sector.

We advise investors to look beyond the headline loss numbers for 2025 and focus on the improving trends in cash flow, margin expansion, and price stability. The "Accumulate" rating reflects our confidence in Tongwei’s ability to deliver sustainable value creation in the coming years.
