Executive Summary

The third quarter of 2025 (3Q25) marks a pivotal, albeit gradual, turning point for the global photovoltaic (PV) industry. After seven consecutive quarters of losses, the sector is exhibiting early signs of stabilization driven by "anti-involution" measures—industry-led efforts to curb irrational price wars and overcapacity. While the main PV supply chain (polysilicon, wafers, cells, modules) has seen a sequential improvement in gross and net margins due to price repairs, profitability remains fragile. Conversely, the auxiliary supply chain has remained largely flat in terms of revenue and profit performance.

Despite these marginal improvements, structural challenges persist. Capital expenditure (CapEx) remains subdued as companies prioritize survival over expansion, yet balance sheets remain stressed with high debt-to-asset ratios. Inventory levels, particularly in polysilicon, remain elevated, and short-term net cash flow for main chain manufacturers continues to deteriorate. Looking ahead, we maintain a constructive view on the sector’s valuation repair, underpinned by the ongoing supply-side clearing and the emergence of new technologies. We estimate long-term global PV installation growth to stabilize at a moderate 5–10% CAGR, shifting the investment narrative from high-growth speculation to value recovery and technological alpha.

Key Takeaways

1. Financial Performance: Main Chain Stabilizes, Auxiliary Chain Flatlines

• Main Supply Chain: Benefiting from a repair in product prices, the main产业链 (polysilicon through modules) recorded a sequential reduction in losses in 3Q25. Both gross and net profit margins improved quarter-over-quarter (QoQ). This indicates that the "bottoming out" phase of profitability is underway, although absolute profits remain negative or minimal for many players.
• Auxiliary Supply Chain: Revenue and profits in the auxiliary segment (glass, inverters, mounting structures, etc.) remained broadly flat QoQ, tracking closely with overall shipment volumes rather than experiencing significant margin expansion.

2. Balance Sheet & Cash Flow: Survival Mode Prevails

• Capital Expenditure: Industry CapEx remains at historically low levels. Amidst widespread losses, corporate willingness to expand capacity has diminished significantly. This contraction in new supply is a critical prerequisite for market rebalancing.
• Leverage: The industry-wide debt-to-asset ratio remained largely unchanged in 3Q25. However, there is a slight structural improvement in the cell manufacturing segment. Overall, deleveraging remains a primary objective for most firms, with many still carrying excessive debt burdens that need to be reduced to sustainable levels.
• Cash Flow & Inventory: Short-term net cash flow for the main supply chain continued to decline sequentially, reflecting ongoing working capital pressures. Inventory levels have risen, with polysilicon factory inventories remaining at high levels. This inventory overhang poses a near-term headwind to further price increases.

3. Demand Outlook: Moderate Growth Trajectory

• Domestic Market: Following a rush-to-install period in 2Q25 which drove high growth, monthly grid-connected installations in China have declined rapidly as the market entered its traditional off-season.
• Global Growth Forecast: Despite the high economic viability of energy storage, the logic of "PV + Storage" fully replacing traditional power sources has not yet materialized at scale. Currently, PV generation primarily serves to meet incremental electricity demand rather than displacing existing baseload capacity. Consequently, we project the annual growth rate for global new PV installations to stabilize in the 5–10% range. This suggests a shift from hyper-growth to steady, utility-scale expansion.

4. The "Anti-Involution" Narrative: Path to Valuation Repair

• Price Dynamics: Since the initiation of anti-involution measures, polysilicon prices have rebounded from RMB 34,000/ton to RMB 51,000/ton. This price recovery has begun to transmit downstream to wafers and cells. However, module prices have remained stagnant due to resistance from power plant developers who are sensitive to upfront CAPEX.
• Supply Clearing: The industry is undergoing a natural clearing process. According to Black Eagle PV statistics, over 100 PV enterprises went bankrupt in 2024, and more than 50 filed for bankruptcy in 1H25. This exit of inefficient capacity is essential for restoring healthy supply-demand dynamics.
• Valuation Implication: As the anti-involution mechanism matures and prices return to rational levels, we anticipate a systematic valuation repair across the sector. The current market pricing reflects extreme pessimism, offering an asymmetric risk-reward profile for long-term investors.

5. Investment Themes: Supply-Side Reform & Technological Innovation

We identify two primary investment avenues:
1. Valuation Repair via Supply Optimization: Companies in the polysilicon, wafer, cell, and module segments that survive the current consolidation phase are poised for multiple expansion as profitability normalizes.
2. Technological Alpha: Innovations that drive cost reduction and efficiency gains offer distinct opportunities. Key areas include:
* Copper replacing Silver in pastes: Reducing material costs in metallization.
* Perovskite Cells: Recent tendering activities for perovskite projects are creating new demand streams for specialized equipment manufacturers.

Risks / Headwinds

Investors should remain cognizant of the following risks that could derail the recovery thesis:

• Demand Disappointment: If global or domestic installation targets are missed, enterprise profitability could deteriorate further, extending the loss-making period.
• Slow Supply Clearing: If the "anti-involution" measures fail to effectively curb output or if bankruptcy proceedings are delayed, companies will continue to burn cash, exacerbating financial stress and potentially leading to liquidity crises.
• Geopolitical Friction: Escalating global trade protectionism could erect new supply chain barriers, restricting market access for Chinese PV manufacturers and disrupting global trade flows.
• Technology Execution Risk: Slower-than-expected progress in copper-paste adoption or delays in perovskite battery tendering could dampen sentiment towards technology-enabled growth stocks.

Rating / Sector Outlook

Sector Outlook: Positive (Overweight)
Rating Rationale: While the near-term financials remain weak, the worst of the cycle appears to be behind us. The combination of suppressed CapEx, active supply-side clearing (bankruptcies), and initial price stabilization in upstream materials supports a "bottom-fishing" thesis. The sector is transitioning from a phase of chaotic competition to one of rationalized supply, which historically precedes significant valuation recovery.

We recommend focusing on leaders with robust balance sheets capable of weathering the remaining cash-flow pressures, as well as equipment providers benefiting from the next generation of PV technology (Perovskite/Copper paste).

Investment View

The 3Q25 earnings season confirms that the PV industry is at an inflection point. The narrative has shifted from "growth at all costs" to "survival and rationalization." For institutional investors, the current environment presents a strategic entry point for long-term allocation, predicated on three core logics:

1. Profit Bottom Confirmed: Seven quarters of losses have forced a hard reset in industry expectations. With polysilicon prices rebounding and CapEx frozen, the supply-demand imbalance is slowly correcting.
2. Valuation Disconnect: Current valuations do not fully price in the eventual return to normalized profitability. As the "anti-involution" policies take full effect, we expect a re-rating of major integrated manufacturers.
3. Tech-Driven Differentiation: In a mature, slow-growth market (5–10% CAGR), alpha will be generated by companies that can lower LCOE (Levelized Cost of Energy) through technological innovation. Equipment makers involved in the Perovskite transition and material innovators (Cu-agents) offer higher growth potential than generic capacity providers.

Strategy: Accumulate positions in high-quality main-chain leaders with improving cash flows and selective exposure to next-gen technology enablers. Monitor inventory levels and bankruptcy rates as key leading indicators for the pace of recovery.
