Executive Summary

Tongwei Co., Ltd. (“Tongwei” or the “Company”), a global leader in high-purity crystalline silicon and solar cells, released its third-quarter financial report for 2025 on October 24. The results indicate a pivotal turning point in the company’s operational trajectory, driven by significant improvements in the polysilicon segment. While the cumulative net profit for the first nine months of 2025 remained negative at CNY -5.27 billion, reflecting the lingering effects of industry-wide price wars in earlier periods, the third quarter (Q3) demonstrated a marked reduction in losses. Q3 attributable net profit stood at CNY -315 million, a substantial sequential improvement from the CNY -2.36 billion loss recorded in Q2 2025. This performance exceeded market consensus expectations, signaling that the worst of the profitability compression may have passed.

The core driver of this turnaround is the dual benefit of rising polysilicon prices and falling production costs. Since July 2025, the Chinese photovoltaic (PV) industry has intensified its efforts to curb "involution" (destructive internal competition), leading to a disciplined supply side and a consequent rebound in polysilicon prices. Concurrently, the onset of the wet season in Sichuan and Yunnan provinces reduced electricity costs for Tongwei’s production facilities, further enhancing margins. Our analysis suggests that the polysilicon business likely achieved break-even or slight profitability in Q3, acting as the primary stabilizer for the Company’s overall financial health.

However, challenges persist in the downstream battery and module segments. Despite the upstream recovery, battery and module prices have seen limited increases, while input costs have risen. Consequently, these segments remain under pressure and are estimated to be operating at a loss. Nevertheless, Tongwei’s robust balance sheet, characterized by strong cash reserves and improved operating cash flow, positions it well to weather the ongoing cycle. With total monetary funds and transactional financial assets reaching approximately CNY 34.8 billion by the end of Q3, the Company possesses the financial resilience to sustain operations and invest in technological leadership while weaker competitors exit the market.

We maintain our BUY rating on Tongwei shares. We view the Company as a primary beneficiary of the industry’s structural consolidation ("anti-involution") policies. With industry-leading cost advantages in polysilicon, dominant market share in high-efficiency cells, and rapidly growing module exports, Tongwei is strategically positioned to capture disproportionate value as the PV sector’s fundamentals bottom out and recover. We have adjusted our earnings forecasts for 2025-2027 to reflect the latest pricing dynamics, projecting a return to profitability in 2026.

Key Takeaways

1. Q3 Performance: Significant Loss Reduction and Operational Resilience

The third quarter of 2025 marked a critical inflection point for Tongwei. The Company reported quarterly revenue of CNY 24.1 billion, representing a year-over-year (YoY) decline of only 1.6%, indicating stabilization in top-line growth despite the challenging macro environment. More importantly, the bottom-line performance showed dramatic improvement.

• Net Profit Trajectory: The attributable net profit for Q3 was CNY -315 million. While still negative, this represents a massive sequential reduction in losses compared to Q2 2025 (CNY -2.363 billion). The magnitude of this improvement—approximately CNY 2.05 billion quarter-on-quarter—underscores the effectiveness of cost control measures and the positive impact of rising polysilicon prices.
• Year-to-Date Context: For the first nine months of 2025, total revenue amounted to CNY 64.6 billion, a YoY decrease of 5.4%. The cumulative attributable net loss widened to CNY -5.27 billion. This cumulative figure is heavily weighted by the severe losses incurred in H1 2025, when polysilicon prices were at cyclical lows. The Q3 data confirms that the bleeding has significantly slowed, validating our thesis that the industry bottom has been established.

The beat against expectations was primarily driven by the polysilicon segment. Market participants had anticipated continued deep losses across all business lines due to persistent oversupply narratives. However, the rapid policy-driven correction in polysilicon pricing allowed Tongwei to mitigate losses faster than anticipated.

2. Polysilicon Segment: The Engine of Recovery

The polysilicon business, historically Tongwei’s cash cow and competitive moat, experienced a profound rehabilitation in Q3 2025. This recovery was driven by two distinct factors: price appreciation due to supply-side discipline and cost reduction due to seasonal energy advantages.

A. Price Recovery Driven by "Anti-Involution" Policies

The Chinese PV industry has been grappling with severe overcapacity and price wars, often referred to as "involution," where companies sell below cost to maintain market share, eroding industry-wide profitability. In response, industry associations and regulatory bodies have intensified efforts to stabilize the market starting in mid-2025.

• Price Surge: According to data from the China Nonferrous Metals Industry Association Silicon Branch, the price of N-type dense material (a key premium polysilicon product) rose significantly. By the end of September 2025, prices reached CNY 49,700 per ton.
• Magnitude of Increase: This represents a 56% increase from the cyclical low recorded at the end of June 2025.
• Quarterly Average Impact: The average selling price (ASP) for N-type dense material in Q3 2025 was CNY 43,100 per ton, a 24% quarter-on-quarter (QoQ) increase from the Q2 average of CNY 34,800 per ton.

This price recovery was not merely a spot market fluctuation but a structural shift driven by coordinated production cuts and stricter quality standards enforced by industry leaders. As the largest producer of high-purity crystalline silicon globally, Tongwei benefits disproportionately from this price normalization. The 24% QoQ price increase directly flowed through to the top line, offsetting volume pressures and driving margin expansion.

B. Cost Advantage Amplified by Wet Season Electricity Rates

Tongwei’s production footprint is strategically located in Sichuan and Yunnan provinces, regions rich in hydropower resources. This geographic advantage provides a variable cost structure that fluctuates with seasonal water availability.

• Wet Season Benefit: Q3 coincides with the "wet season" in Southwest China, where abundant rainfall leads to lower hydroelectricity tariffs. Since electricity constitutes a significant portion (often 30-40%) of polysilicon production costs, this seasonal dip in energy prices materially lowers the cost of goods sold (COGS).
• Margin Expansion Mechanism: The combination of higher selling prices (+24% QoQ) and lower production costs (due to wet season rates) created a powerful scissors effect on gross margins. Our modeling indicates that this dual dynamic likely pushed the polysilicon segment back into breakeven or modest profitability in Q3, a stark contrast to the deep losses incurred in Q2 when prices were low and electricity costs were higher (dry season transition).

Margin Impact: 
[Price ↑ 24% QoQ] + [Cost ↓ Wet Season] = [Profitability Repair]

The Company’s ability to leverage its low-cost position during periods of price volatility remains its strongest defensive attribute. Even when prices were at their lowest in H1, Tongwei’s losses were smaller than those of higher-cost peers. As prices recover, Tongwei’s margins expand faster, reinforcing its status as the industry’s cost leader.

3. Battery and Module Segment: Under Pressure but Strategically Positioned

While the upstream polysilicon segment recovered, the downstream battery and module businesses continued to face headwinds in Q3 2025. This divergence highlights the uneven nature of the current industry recovery, where upstream raw materials have stabilized faster than downstream finished goods.

A. Continued Profitability Challenges

• Price Stickiness: Unlike polysilicon, battery and module prices did not experience a commensurate rise in Q3. The transmission of upstream cost increases to downstream products was limited due to intense competition and cautious demand from project developers.
• Cost Squeeze: With polysilicon prices rising, the input costs for wafer and cell manufacturing increased. However, unable to fully pass these costs onto customers, the gross margins for the battery and module segments compressed further.
• Loss Status: Our estimates suggest that the battery and module business remained in a loss-making state during Q3. This drag on overall performance prevented the Company from achieving full net profitability in the quarter, despite the polysilicon recovery.

B. Strategic Strengths Amidst Weaknesses

Despite the current financial pressure, Tongwei’s downstream business retains strong strategic fundamentals that position it for future outperformance once the broader market balances:

1. Technology Leadership: Tongwei continues to lead in high-efficiency cell technologies, particularly in TOPCon and HJT (Heterojunction) segments. Its R&D capabilities ensure that its products command a premium in terms of efficiency and reliability, which is increasingly valued by tier-1 module buyers.
2. Sales Volume Leadership: The Company maintains a leading market share in cell shipments. This scale provides bargaining power and ensures utilization rates remain relatively high even in a downturn, spreading fixed costs more effectively than smaller rivals.
3. High-Growth Module Exports: A notable bright spot is the rapid growth in overseas module shipments. International markets, particularly in Europe, the Middle East, and emerging Asia, offer higher margins than the domestic Chinese market. Tongwei’s aggressive expansion in these regions is helping to diversify its revenue base and mitigate the impact of domestic price wars.

C. Outlook: Waiting for Policy Catalysts

The outlook for the battery and module segments hinges on the broader implementation of "anti-involution" policies. We anticipate that subsequent policy measures will extend beyond polysilicon to cover capacity controls and quality standards for modules and cells. These may include:
* Restrictions on new capacity approvals.
* Stricter energy consumption standards for manufacturing.
* Minimum price guidelines or anti-dumping investigations.

As these measures take effect, we expect the supply-demand imbalance in the downstream sectors to correct, allowing prices to stabilize and margins to repair. Tongwei, with its integrated model and technological edge, is well-placed to capture this upside.

4. Financial Health: Robust Cash Flow and Liquidity

One of the most compelling aspects of Tongwei’s Q3 report is the significant improvement in cash flow generation and the strength of its balance sheet. In capital-intensive industries like solar manufacturing, liquidity is king during downturns. Tongwei has demonstrated exceptional financial discipline.

A. Operating Cash Flow Turnaround

• Q3 Operating Cash Flow: The net cash flow from operating activities surged to CNY 4.78 billion in Q3 2025. This is a dramatic reversal from previous quarters and indicates a substantial improvement in the quality of earnings.
• Drivers of Cash Flow Improvement:
  1. Working Capital Management: Improved collection of receivables and optimized inventory levels.
  2. Profitability Recovery: The reduction in losses in the polysilicon segment directly contributed to cash generation.
  3. Non-Cash Adjustments: Depreciation and amortization, being significant in this asset-heavy business, add back to cash flow, but the core operational improvement is evident in the magnitude of the inflow.

This positive operating cash flow demonstrates that the business is self-sustaining at current price levels, reducing the need for external financing to fund day-to-day operations.

B. Strong Liquidity Position

• Cash Reserves: As of the end of Q3 2025, Tongwei held total monetary funds and transactional financial assets of approximately CNY 34.8 billion. This represents a 5% sequential increase from the end of Q2.
• Financing Flexibility: The Company maintains ample unused bank credit lines and has active access to diverse financing instruments, including super short-term commercial paper and medium-term notes. This financial flexibility ensures that Tongwei can:
  1. Weather prolonged periods of low profitability if necessary.
  2. Continue investing in R&D and next-generation technologies (e.g., BC cells, perovskite tandem) while competitors cut back.
  3. Pursue strategic M&A opportunities if distressed assets become available.

Table 2: Liquidity and Solvency Metrics (End of Q3 2025)

The robust cash position serves as a critical competitive advantage. In an industry where many smaller players are facing liquidity crises and potential bankruptcy, Tongwei’s financial strength allows it to maintain market share and potentially gain share as weaker exits occur. This "survival of the fittest" dynamic is a key long-term bullish thesis for the Company.

5. Earnings Forecast and Valuation Adjustment

Based on the latest industry price trends and Q3 operational data, we have updated our financial models for Tongwei. The key adjustment reflects the faster-than-expected recovery in polysilicon margins, offset by continued pressure in downstream segments.

A. Revised Earnings Estimates

We adjust our attributable net profit forecasts for 2025-2027 as follows:

• 2025E: CNY -5.53 billion (Previously estimated higher loss). The reduction in the forecasted loss is driven by the Q3 beat and expected Q4 stability.
• 2026E: CNY 3.04 billion. We project a return to profitability as industry-wide capacity rationalization takes hold and prices stabilize at sustainable levels.
• 2027E: CNY 6.13 billion. Continued growth driven by volume expansion in high-efficiency modules and normalized margins across the integrated value chain.

B. Valuation Analysis

At the current share price of CNY 22.21, the stock trades at:
* 2026E P/E: ~33x
* 2027E P/E: ~16x

While the forward P/E appears elevated relative to historical averages for mature manufacturing firms, it is important to contextualize this within the cyclical nature of the PV industry.
1. Cyclical Bottom Valuation: Investors typically look through the current losses (2025) and value the company based on normalized earnings in the recovery phase (2026-2027). A 2027E P/E of 16x is reasonable for a market leader with superior cost structures and technology advantages.
2. PB Ratio: The Price-to-Book ratio is approximately 2.24x for 2025E and 1.96x for 2027E. Given the Company’s strong ROE recovery trajectory (projected 12% by 2027), this valuation supports a premium for quality and resilience.
3. Peer Comparison: Compared to integrated peers who may lack Tongwei’s polysilicon cost advantage or cell technology leadership, Tongwei warrants a valuation premium due to its lower risk profile during downturns and higher upside during recoveries.

We believe the market is currently underappreciating the speed of the polysilicon margin recovery and the durability of Tongwei’s cash flow generation. As visibility on 2026 profitability improves, we expect multiple expansion to accompany earnings growth.

Risks / Headwinds

While our outlook is positive, investors must consider several key risks that could impact Tongwei’s performance and stock price.

1. Product Price Volatility

The PV industry is notoriously cyclical, and prices for polysilicon, wafers, cells, and modules are highly sensitive to supply-demand imbalances.
* Downside Risk: If the "anti-involution" policies fail to effectively curb capacity expansion, or if new large-scale capacities come online faster than expected, polysilicon prices could retreat from their current levels. A reversion to sub-CNY 40,000/ton prices would severely compress margins and delay the return to profitability.
* Upside Risk: Conversely, if demand surges unexpectedly, prices could spike, benefiting Tongwei. However, regulatory intervention to cap prices might limit this upside.

2. Intensified Industry Competition

Despite consolidation efforts, competition remains fierce.
* Technological Disruption: The rapid evolution of PV technology (e.g., from PERC to TOPCon to HJT and BC) requires continuous heavy R&D investment. If Tongwei fails to maintain its technological lead, or if a competitor introduces a breakthrough technology with significantly lower costs, Tongwei’s market share and pricing power could erode.
* Price Wars: If smaller players, desperate for cash flow, engage in aggressive pricing despite losses, it could prolong the downturn and force Tongwei to choose between maintaining market share (at the cost of margins) or ceding share (at the cost of scale).

3. Demand Uncertainty

Global PV 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 solar projects, dampening installation rates.
* Policy Changes: Subsidy reductions or changes in net-metering policies in major markets could slow down adoption.
* Geopolitical Tensions: Trade barriers, such as tariffs or import restrictions in the US, Europe, or India, could limit Tongwei’s export growth, particularly in the high-margin module segment.

4. Execution and Operational Risks

• Capacity Utilization: If demand falls short of expectations, Tongwei’s large fixed asset base could lead to high unit costs due to underutilization.
• Supply Chain Disruptions: Dependence on specific raw materials or equipment suppliers could pose risks if geopolitical or logistical issues arise.

5. Financial Risks

• Asset Impairment: Rapid technological shifts can render existing production lines obsolete, potentially leading to significant asset impairment charges, as seen in previous years.
• Debt Servicing: While liquidity is strong, the Company carries significant debt. A prolonged period of negative cash flow could strain interest coverage ratios, although current metrics suggest this risk is manageable.

Rating / Sector Outlook

Sector Outlook: Photovoltaic Industry

The global photovoltaic industry is currently navigating a complex transition phase characterized by structural consolidation and technological iteration.

1. From Quantity to Quality: The era of unchecked capacity expansion is ending. Regulatory and industry-led initiatives ("anti-involution") are shifting the focus towards high-quality, efficient, and sustainable production. This favors established leaders with strong balance sheets and technological prowess, such as Tongwei.
2. Supply-Demand Rebalancing: We are witnessing the early stages of supply-side clearing. High-cost producers are exiting or reducing output, which is gradually restoring pricing power to leaders. We expect this trend to accelerate in 2026, leading to a healthier industry ecosystem.
3. Technology as a Differentiator: N-type technologies (TOPCon, HJT, BC) are becoming the standard. Companies that can manufacture these at scale with high yields and low costs will dominate the next cycle. Tongwei’s leadership in cell efficiency places it at the forefront of this trend.
4. Globalization of Demand: While China remains the largest market, growth in emerging markets (Middle East, Southeast Asia, Latin America) and the continued transition in Europe provide diversified demand sources. Companies with strong international distribution networks, like Tongwei, are better positioned to capture this growth.

Investment Theme: "Leadership Premium in a Consolidating Market." We recommend overweighting positions in top-tier integrated manufacturers with proven cost advantages and strong cash flows, while avoiding smaller, highly leveraged players vulnerable to bankruptcy.

Rating Justification: BUY

We maintain our BUY rating on Tongwei Co., Ltd. for the following reasons:

1. Proven Resilience: Q3 results demonstrate the Company’s ability to navigate extreme market conditions, significantly reducing losses despite industry headwinds.
2. Cost Leadership: Tongwei’s polysilicon cost structure is among the lowest globally, providing a durable competitive moat that ensures profitability in upcycles and survival in downcycles.
3. Strategic Positioning: As a leader in both upstream (polysilicon) and midstream (cells) segments, with growing downstream (module) presence, Tongwei benefits from vertical integration efficiencies.
4. Financial Strength: A robust cash position of CNY 34.8 billion and positive operating cash flow provide the flexibility to invest in future growth and withstand further volatility.
5. Valuation Appeal: With the industry bottoming out, the current valuation offers an attractive entry point for long-term investors seeking exposure to the inevitable recovery in solar demand and pricing.

Investment View

Core Investment Logic

Our investment thesis for Tongwei is built on three pillars: Cyclical Recovery, Structural Advantage, and Financial Fortitude.

1. Cyclical Recovery: The "Anti-Involution" Dividend

The Chinese PV industry’s move towards self-discipline is not just a temporary fix but a structural shift. The "anti-involution" campaign is effectively raising the floor for product prices and forcing inefficient capacity out of the market. Tongwei, as the largest polysilicon producer, is the primary beneficiary of this price stabilization.
* Immediate Impact: The 56% rise in polysilicon prices from June to September 2025 has already translated into tangible financial improvement, as evidenced by the Q3 loss reduction.
* Future Upside: As these policies deepen, we expect further margin expansion in 2026. The market is currently pricing in a slow recovery, but our analysis suggests a sharper V-shaped rebound in profitability is possible if supply discipline holds.

2. Structural Advantage: Technology and Scale

Tongwei is not just a commodity producer; it is a technology leader.
* Polysilicon: Its proprietary production techniques and scale allow it to produce high-purity silicon at costs significantly below the industry average. This cost gap widens during price wars, allowing Tongwei to survive when others bleed cash.
* Cells: Tongwei’s dominance in high-efficiency cell production ensures that its downstream modules are competitive. As the industry shifts entirely to N-type cells, Tongwei’s early investment in TOPCon and HJT capacity is paying off in terms of yield and efficiency premiums.
* Integration: The integrated model allows Tongwei to capture value at multiple stages of the value chain. When polysilicon margins are high, the upstream segment drives profits. When module margins improve, the downstream segment contributes. This diversification smooths earnings volatility over the long term.

3. Financial Fortitude: The Ability to Win the War of Attrition

In cyclical industries, the company with the deepest pockets often emerges as the winner. Tongwei’s CNY 34.8 billion cash reserve is a strategic weapon.
* Survival: It ensures the Company can operate without distress even if prices remain subdued for longer than expected.
* Investment: It allows Tongwei to continue R&D and capacity upgrades while competitors cut back, widening the technology gap.
* Consolidation: It positions Tongwei to acquire distressed assets or competitors at attractive valuations, further consolidating its market leadership.

Strategic Recommendations for Institutional Investors

1. Accumulate on Weakness: Given the volatile nature of the PV sector, short-term price fluctuations are likely. Investors should use any dips caused by temporary news flow or broader market sentiment as buying opportunities, focusing on the long-term fundamental recovery.
2. Monitor Policy Implementation: Keep a close watch on the implementation details of "anti-involution" policies. Specific measures regarding capacity caps, energy consumption limits, and quality standards will be key catalysts for stock performance.
3. Track Quarterly Margins: Focus on the gross margin trends in the polysilicon and cell segments. A sustained improvement in Q4 2025 and Q1 2026 will confirm the recovery thesis.
4. Long-Term Hold: Tongwei is a core holding for exposure to the global energy transition. Its leadership position makes it a lower-risk proxy for the solar sector compared to smaller, pure-play module makers or upstream-only suppliers.

Conclusion

Tongwei Co., Ltd. stands at the forefront of the photovoltaic industry’s transformation. The Q3 2025 results serve as a clear signal that the Company has successfully navigated the trough of the cycle. With polysilicon profitability repairing, a robust balance sheet, and leading technology, Tongwei is well-equipped to capitalize on the upcoming industry recovery. We believe the market has yet to fully price in the sustainability of this recovery and the Company’s long-term competitive advantages. Therefore, we maintain our BUY rating, targeting a re-rating of the stock as earnings visibility improves in 2026.

Appendix: Detailed Financial Analysis

1. Income Statement Analysis

Revenue Trends:
The Company’s revenue has stabilized after a sharp decline in 2024. The 1.31% projected growth in 2025 reflects a balance between lower average selling prices in H1 and higher volumes/prices in H2. The 15.28% growth projected for 2026 assumes a full year of normalized prices and continued volume growth in the module segment.

Cost of Goods Sold (COGS):
COGS as a percentage of revenue peaked in 2024 at 93.6%, reflecting the extreme price compression. In 2025E, this ratio remains high at 96.2% due to the lag in downstream price adjustments. However, by 2026E, we project COGS to drop to 87.5% of revenue, driving gross margin expansion to 12.5%. This improvement is driven by:
* Lower polysilicon production costs (wet season efficiencies, technological improvements).
* Higher ASPs for N-type cells and modules.

Operating Expenses:
* Selling Expenses: Stable at around 2.0% of revenue, indicating efficient distribution channels.
* Administrative Expenses: Decreasing as a percentage of revenue (from 4.5% in 2024 to 3.6% in 2025E), reflecting economies of scale and cost control measures.
* R&D Expenses: Maintained at ~1.3% of revenue. This consistent investment is crucial for maintaining technological leadership in a rapidly evolving industry.

EBIT and Net Profit:
EBIT is projected to turn positive in 2026 (CNY 5.49 billion), driven by gross margin recovery. Net profit follows a similar trajectory, with minority interests playing a role in the final attributable profit figure. The significant swing from -CNY 7.04 billion in 2024 to +CNY 3.04 billion in 2026E underscores the cyclical nature of the business and the magnitude of the expected recovery.

2. Cash Flow Statement Analysis

Operating Cash Flow (OCF):
The turnaround in OCF is one of the most positive signals in the report.
* 2024: CNY 1.14 billion (Low, reflecting working capital strain).
* 2025E: CNY 6.19 billion (Improvement driven by Q3-Q4 recovery).
* 2026E: CNY 18.21 billion (Strong generation as profitability returns).
* 2027E: CNY 23.64 billion (Mature cash cow status).

This robust OCF generation validates the Company’s ability to self-fund its operations and reduce reliance on external debt.

Investing Cash Flow:
Capital expenditures (CapEx) remain significant but are managed prudently.
* 2024: -CNY 27.78 billion (Heavy investment in capacity).
* 2025E: -CNY 6.80 billion (Significant reduction, reflecting a shift from expansion to optimization).
* 2026E/2027E: ~-CNY 12.7 billion annually (Sustainable level for maintenance and incremental tech upgrades).

The reduction in CapEx in 2025 is a key factor in the improved free cash flow profile, demonstrating management’s discipline in curbing over-expansion.

Financing Cash Flow:
The Company has been active in debt markets to maintain liquidity.
* 2024: Net inflow of CNY 27.48 billion, primarily from debt issuance, to bolster cash reserves.
* 2025E: Net inflow of CNY 4.80 billion, indicating continued but moderated borrowing.
* 2026E/2027E: Net outflows projected as the Company begins to deleverage using operating cash flows.

3. Balance Sheet Analysis

Asset Structure:
* Current Assets: Increased to CNY 72.78 billion in 2025E, driven by higher cash reserves and inventory buildup in anticipation of sales.
* Non-Current Assets: Dominated by Fixed Assets (CNY 103.78 billion in 2025E), reflecting the capital-intensive nature of the business. The proportion of fixed assets to total assets is decreasing slightly (52.2% in 2025E vs 54.8% in 2024), indicating a maturing asset base.

Liability and Equity:
* Total Liabilities: CNY 146.21 billion in 2025E. The debt-to-asset ratio is high (73.55%), which is typical for the industry during expansion phases. However, the quality of debt is manageable given the strong cash position.
* Shareholders’ Equity: Declined to CNY 44.63 billion in 2025E due to accumulated losses. We project a recovery to CNY 51.04 billion by 2027E as profitability returns.

Solvency Ratios:
* Net Debt/Equity: Peaked at 99.03% in 2025E but is projected to decline to 74.60% by 2027E. This deleveraging trend is supported by strong cash flow generation.
* Interest Coverage: EBIT interest coverage ratio turns positive in 2026 (2.5x) and improves to 4.7x in 2027, indicating comfortable debt servicing capability post-recovery.

4. Key Performance Indicators (KPIs) Monitoring

Investors should monitor the following KPIs in subsequent quarters:

1. Polysilicon ASP: Track the monthly average selling price of N-type dense material. Sustained levels above CNY 45,000/ton are bullish.
2. Cell Shipment Volume: Monitor Tongwei’s market share in high-efficiency cell shipments. Maintenance of leadership is critical.
3. Module Export Growth: Track the percentage of revenue from overseas module sales. Higher exposure to international markets supports margin resilience.
4. Cash Conversion Cycle: Monitor days sales outstanding (DSO) and days inventory outstanding (DIO). Improvements here indicate better working capital management.
5. R&D Yield Rates: Technological yield rates for TOPCon and HJT cells are key indicators of competitive advantage.
