Executive Summary

Flat Glass Group Co., Ltd. ("Flat Glass" or the "Company"), a tier-one leader in the global photovoltaic (PV) glass industry, has released its interim financial results for the first half of 2025 (1H25). The report reflects a period of significant industry-wide adjustment characterized by intense competition, price volatility, and strategic capacity rationalization. While top-line revenue and net profit experienced year-on-year declines due to broader market headwinds, the Company demonstrated resilient operational management, particularly in cash flow generation and overseas business profitability.

The core investment thesis for Flat Glass rests on the inflection point of the PV glass supply-demand dynamics. After a prolonged period of oversupply that drove prices to historic lows in July-August 2025, the industry is witnessing a concerted effort to reduce production through cold repairs and the exit of inefficient capacity. This supply-side contraction, coupled with stabilizing demand, has initiated a price recovery trend starting in late August 2025. We anticipate that Flat Glass’s profitability will begin to repair in September 2025, driven by rising utilization rates among remaining efficient players and improved pricing power.

Despite the near-term earnings pressure, Flat Glass maintains its competitive moat through superior cost control, advanced technological capabilities, and a robust overseas footprint—specifically its Vietnam operations, which continue to deliver higher margins than domestic counterparts. We maintain our "Buy-A" rating, projecting a gradual but steady recovery in earnings per share (EPS) from CNY 0.31 in 2025 to CNY 0.84 in 2027. The current valuation, while reflecting high near-term P/E multiples due to depressed 2025 earnings base, offers an attractive entry point for long-term investors anticipating the cyclical upturn in the PV supply chain.

Key Financial Highlights (1H25 & Q2 2025)

• Revenue: 1H25 revenue stood at CNY 7.74 billion, a year-on-year (YoY) decline of 27.7%. Q2 2025 revenue was CNY 3.66 billion, down 26.4% YoY and 10.3% quarter-on-quarter (QoQ).
• Net Profit: 1H25 attributable net profit was CNY 261 million, down 82.6% YoY. However, Q2 2025 net profit showed sequential improvement, reaching CNY 150 million, a 46.0% QoQ increase, despite a 79.0% YoY decline.
• Cash Flow: Operating cash flow remained robust, totaling CNY 1.40 billion in 1H25. Q2 alone generated CNY 1.23 billion in net operating cash inflow, up 7.8% YoY, underscoring strong working capital management.
• Overseas Performance: Overseas revenue accounted for 30.1% of total revenue (up 7.2 percentage points YoY), with a gross margin of 18.4%. The Vietnam subsidiary contributed CNY 140 million in net profit, highlighting the strategic value of international diversification.

Key Takeaways

1. Industry Cycle Inflection: From "Involution" to Rationalization

The PV glass sector has undergone a severe correction in 2024 and 1H2025, driven by aggressive capacity expansion in previous years and a temporary mismatch between supply and downstream module demand. The phenomenon of "involution" (intense, often destructive internal competition) led to prices falling below the cash cost of many producers.

The Price Trajectory and Bottoming Out

• Early 2025 Volatility: A rush installation boom in March-April 2025 provided a temporary boost to PV glass prices. However, as this demand pulse faded, prices resumed their downward trajectory.
• Historic Lows: By July and August 2025, PV glass prices plummeted to approximately CNY 10/m², a historic low that rendered a significant portion of industry capacity unprofitable.
• Supply Response: In response to unsustainable margins, the industry initiated widespread production cuts. Leading enterprises, including Flat Glass, actively reduced output. By the end of June 2025, Flat Glass’s operating capacity was adjusted to 16,400 tons/day (t/d).
• Industry-Wide Contraction: According to Shanghai Metals Market (SMM) data, the overall industry operating rate dropped to 51.6% in August 2025. This significant reduction in active supply helped alleviate inventory pressure, with industry inventory days decreasing to 21.6 days.
• Price Rebound: The supply-demand balance began to tighten in late August. Prices for 2.0mm single-layer coated PV glass rebounded to approximately CNY 13/m² by the end of August 2025. This 30% price increase from the July lows marks a critical turning point.

Implications for Flat Glass

As a low-cost producer with scale advantages, Flat Glass is positioned to benefit disproportionately from this price recovery. While high-cost competitors may remain sidelined or exit the market, Flat Glass can ramp up utilization as prices rise above marginal costs, thereby expanding margins. We expect the company’s profitability to show visible signs of repair starting in September 2025, aligning with the sustained price stabilization.

2. Operational Resilience: Cash Flow Strength and Overseas Alpha

In a downturn, cash flow is king. Flat Glass’s ability to generate positive and growing operating cash flow amidst declining profits is a testament to its operational excellence and strong bargaining power within the supply chain.

Robust Cash Flow Generation

• 1H25 Operating Cash Flow: The company recorded a net operating cash flow of CNY 1.40 billion.
• Q2 Acceleration: Notably, Q2 2025 saw a net inflow of CNY 1.23 billion, representing a 7.8% YoY increase. This counter-intuitive growth in cash flow despite a drop in net profit suggests efficient management of receivables, payables, and inventory levels. It also indicates that the company is successfully converting sales into cash, reducing exposure to bad debts in a challenging market environment.
• Strategic Importance: Strong cash reserves provide Flat Glass with the financial flexibility to weather the downturn, invest in technological upgrades, and potentially pursue opportunistic M&A or capacity optimization without relying heavily on external financing in a high-interest-rate or tight-credit environment.

Overseas Business: A Profitability Anchor

Flat Glass’s international strategy, particularly its manufacturing footprint in Vietnam, has proven to be a significant differentiator.

• Revenue Mix Shift: Overseas revenue reached CNY 2.33 billion in 1H25. Although this represents a 4.8% YoY decline in absolute terms, its share of total revenue increased by 7.2 percentage points to 30.1%. This shift indicates that overseas markets are becoming relatively more important as domestic margins compress.
• Superior Margins: The gross margin for overseas business stood at 18.4%, significantly higher than the domestic average. This premium is driven by:
  1. Trade Policy Arbitrage: Avoidance of certain trade barriers and tariffs applicable to Chinese mainland exports.
  2. Market Pricing: Higher willingness to pay in certain international markets.
  3. Cost Efficiency: The Vietnam facility benefits from localized supply chains and potentially lower energy/labor costs relative to the value added.
• Vietnam Subsidiary Contribution: Flat Glass (Vietnam) generated a net profit of CNY 140 million in 1H25. This single entity contributed more than half of the Company’s total attributable net profit (CNY 261 million), highlighting its role as the primary profit engine during the domestic downturn.
• Strategic Outlook: As global PV deployment continues to grow, particularly in regions seeking supply chain diversification (e.g., Europe, Middle East, US-aligned markets), Flat Glass’s overseas capacity will be crucial. We expect the company to further optimize its global footprint, potentially expanding beyond Vietnam to mitigate geopolitical risks and capture higher-margin opportunities.

3. Competitive Positioning: Tier-1 Status and Cost Leadership

Flat Glass remains one of the two dominant players in the global PV glass market (alongside Xinyi Solar). Its "Tier-1" status is not merely a function of size but of structural competitive advantages that become more pronounced during industry consolidations.

Scale and Cost Advantages

• Large Furnace Technology: Flat Glass has pioneered the use of large-tonnage kilns (1,000 t/d and above). Larger furnaces offer significant economies of scale in terms of energy consumption per unit of output and labor efficiency. As energy costs (natural gas, electricity) constitute a major portion of PV glass production costs, this technological edge translates directly into a lower break-even point.
• Raw Material Procurement: The company’s scale allows for bulk purchasing of silica sand and soda ash, securing better pricing and supply stability. Long-term contracts with key suppliers further mitigate input cost volatility.
• Integrated Supply Chain: Flat Glass has vertically integrated aspects of its supply chain, including self-supply of some raw materials and logistics, enhancing control over costs and delivery timelines.

Technological Innovation

• Thin and Double-Glass Modules: The industry trend towards thinner glass (2.0mm and below) and double-glass modules requires advanced manufacturing precision. Flat Glass has a high yield rate in producing thin, coated glass, which commands a premium and is increasingly preferred by module manufacturers for bifacial modules.
• R&D Investment: Despite cost pressures, the company maintains robust R&D spending (CNY 481 million in 1H25 estimates based on full year trends, though specific 1H R&D is part of the expense structure). This focus ensures readiness for next-generation technologies such as perovskite-tandem compatible glass and enhanced anti-reflective coatings.

Capacity Rationalization Strategy

Unlike smaller players who may be forced into involuntary shutdowns due to cash crunches, Flat Glass is proactively managing its capacity. The reduction to 16,400 t/d by June 2025 was a strategic decision to align supply with demand and support price stability. This disciplined approach helps prevent excessive inventory buildup and protects long-term brand value and customer relationships. When demand recovers, Flat Glass can restart cold-repaired lines faster and more efficiently than competitors who may have let their assets deteriorate.

4. Financial Analysis and Forecast

Historical Performance Review

• 2023 Full Year: Revenue CNY 21.52 billion (+39.2% YoY); Net Profit CNY 2.76 billion (+30.0% YoY). This was a peak year driven by high demand and favorable pricing.
• 2024 Full Year: Revenue CNY 18.68 billion (-13.2% YoY); Net Profit CNY 1.01 billion (-63.5% YoY). The onset of oversupply and price wars began to erode margins significantly. Gross margin contracted from 21.8% in 2023 to 15.5% in 2024.
• 1H2025: The trend of compression continued. Revenue CNY 7.74 billion; Net Profit CNY 261 million. Gross margin remained under pressure at ~15.4% (estimated based on full year guidance and H1 performance).

Forward-Looking Estimates (2025-2027)

We project a "U-shaped" recovery for Flat Glass’s financials. 2025 represents the trough, with subsequent years showing steady improvement as the industry clears excess capacity and demand grows.

Note: Data sourced from Shanxi Securities Research Institute estimates.

Analysis of Forecasts:
* 2025E: We anticipate revenue to decline further to CNY 15.05 billion (-19.5% YoY) as the full impact of lower average selling prices (ASPs) and reduced volume from cold repairs is realized. Net profit is expected to fall to CNY 727 million (-27.7% YoY). This reflects the "trough" year where margins are compressed, and fixed costs are spread over lower production volumes. EPS is forecast at CNY 0.31.
* 2026E: A modest recovery is expected. Revenue should grow 14.8% to CNY 17.27 billion as new global PV installations accelerate and prices stabilize at a healthier level. Net profit is projected to rise 49.4% to CNY 1.09 billion. Margin expansion (Gross Margin to 16.5%) will be driven by better capacity utilization and stable raw material costs. EPS forecast at CNY 0.46.
* 2027E: Strong growth phase. Revenue jumps 40.6% to CNY 24.28 billion, assuming significant global PV adoption and potential new capacity coming online efficiently. Net profit surges 82.0% to CNY 1.98 billion. Gross margin improves to 17.2%, approaching pre-downturn levels but reflecting a more mature, competitive landscape. EPS forecast at CNY 0.84.

Balance Sheet and Cash Flow Health

• Asset Structure: Total assets are projected to decrease slightly in 2025 (CNY 39.27 billion) before growing in 2026-2027. This reflects a conservative approach to capital expenditure during the downturn.
• Liabilities: The company is actively deleveraging. Total liabilities are expected to drop from CNY 21.14 billion in 2024 to CNY 16.75 billion in 2025, primarily through repayment of long-term borrowings (from CNY 11.01 billion to CNY 7.60 billion). This strengthens the balance sheet and reduces interest expenses.
• Cash Position: Cash and equivalents are expected to remain healthy, supporting operations and strategic initiatives. Operating cash flow is forecast to remain positive at CNY 3.21 billion in 2025, ensuring liquidity.
• ROE Trajectory: Return on Equity (ROE) is expected to bottom at 3.3% in 2025, recovering to 4.7% in 2026 and 7.8% in 2027. While still below the 12.4% seen in 2023, this trajectory confirms the cyclical recovery narrative.

Risks / Headwinds

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

1. Intensified Industry Competition

• Risk Description: Despite current capacity cuts, the PV glass industry still has substantial idle capacity that can be restarted if prices rise too quickly. If competitors resume production aggressively, it could lead to a renewed supply glut, suppressing price recovery.
• Impact: Could keep gross margins below our 16.5-17.2% forecasts for 2026-2027. Price wars could re-emerge, eroding the profitability of even efficient players like Flat Glass.
• Mitigation: Monitor industry operating rates and inventory levels closely. Flat Glass’s cost leadership provides a buffer, but sustained low prices would still hurt earnings.

2. Downstream PV Demand Uncertainty

• Risk Description: The demand for PV glass is derived from the installation of solar modules. Global PV demand is subject to macroeconomic conditions, interest rate environments, and policy shifts. If global economic growth slows, or if key markets (Europe, US, China) reduce subsidies or face grid connection bottlenecks, module shipments could fall short of expectations.
• Impact: Lower-than-expected demand would extend the period of oversupply, delaying the price rebound and volume growth. Our 2026-2027 revenue growth assumptions rely on robust global PV installation growth.
• Mitigation: Diversification of geographic markets helps, but a global slowdown would be difficult to offset entirely.

3. Raw Material and Fuel Price Volatility

• Risk Description: The primary costs for PV glass are soda ash, silica sand, and energy (natural gas/electricity). Prices for these inputs are volatile and influenced by global commodity markets and local regulatory policies.
• Impact: A sharp increase in soda ash or natural gas prices without a corresponding increase in PV glass prices would squeeze margins. Given the thin margins in the current environment, even small cost increases can significantly impact net profit.
• Mitigation: Flat Glass uses long-term contracts and vertical integration to mitigate some risk, but it cannot fully insulate itself from broad commodity spikes.

4. Geopolitical and Trade Policy Risks

• Risk Description: The PV industry is highly sensitive to trade policies. Tariffs, anti-dumping duties, and local content requirements in key markets (US, EU, India) can disrupt supply chains. Specifically, changes in trade rules affecting Vietnamese exports could impact Flat Glass’s high-margin overseas business.
• Impact: Loss of access to high-margin markets or imposition of heavy tariffs would reduce the profitability of the overseas segment, which is currently a key profit driver.
• Mitigation: Continuous monitoring of trade policies and potential diversification of overseas manufacturing locations (e.g., considering other Southeast Asian countries or local partnerships).

5. Capacity Construction and Execution Risks

• Risk Description: Delays in new capacity construction or technical issues in restarting cold-repaired lines could hinder the company’s ability to capture market share during the upcycle.
• Impact: Missed revenue opportunities and higher capital costs.
• Mitigation: Flat Glass has a strong track record of execution, but unforeseen technical or regulatory delays are always possible.

6. Exchange Rate Fluctuations

• Risk Description: With 30% of revenue coming from overseas, fluctuations in the RMB exchange rate against the USD and other currencies can impact reported earnings.
• Impact: A strengthening RMB could reduce the value of overseas earnings when converted back to CNY. Conversely, a weakening RMB boosts reported earnings but may increase the cost of imported equipment or materials.
• Mitigation: Use of hedging instruments, though this adds complexity and cost.

Rating / Sector Outlook

Sector Outlook: Cautiously Optimistic on Cyclical Recovery

The PV glass sector is transitioning from a phase of "clearing" to "rebalancing." The extreme oversupply of 2024 and early 2025 has forced a necessary correction. The recent price rebound to CNY 13/m² is a positive signal, but sustainability is key.

• Supply Side: We expect supply growth to remain muted in the next 12-18 months as manufacturers prioritize profitability over market share. Cold repairs will continue, and new capacity approvals may face stricter regulatory scrutiny in China to prevent future overcapacity.
• Demand Side: Global PV installations are expected to grow mid-to-high single digits to low double digits annually, driven by energy transition goals. However, growth rates may moderate compared to the explosive growth of 2022-2023.
• Pricing Power: Pricing power is shifting back towards leading manufacturers with cost advantages. The era of "anyone can make money" is over; the industry is consolidating around efficient, scaled players.

Conclusion: The sector outlook is improving, but the recovery will be gradual rather than V-shaped. Investors should expect a period of margin stabilization followed by slow expansion.

Company Rating: Buy-A (Maintained)

We maintain our Buy-A rating for Flat Glass Group (601865.SH).

Rationale:
1. Valuation: At a current price of CNY 16.74, the stock trades at a 2025E P/E of 53.9x. While this appears high, it is distorted by the depressed earnings base of 2025. Looking forward, the 2026E P/E of 36.1x and 2027E P/E of 19.8x are more reasonable for a growth company in a recovering cyclical industry. The P/B ratio of 1.8x (2025E) is consistent with historical averages for high-quality manufacturing leaders.
2. Leadership Premium: Flat Glass deserves a valuation premium due to its Tier-1 status, cost leadership, and strong balance sheet. In a consolidating market, leaders gain market share and pricing power.
3. Catalysts:
* Q3 2025 Earnings: Expectation of sequential profit improvement in Q3 and Q4 2025 as prices stabilize.
* Industry Data: Continued decline in industry inventory and sustained price levels above CNY 12-13/m².
* Overseas Expansion: Potential announcements regarding new overseas facilities or expanded capacity in Vietnam.
4. Risk-Reward: The downside risk is limited by the company’s strong asset base and cash flow. The upside potential is significant if the industry recovery accelerates or if Flat Glass gains more market share than anticipated.

Target Price Consideration:
While a specific target price is not explicitly recalculated in this update, the maintenance of the "Buy" rating implies confidence that the stock will outperform the benchmark (CSI 300) over the next 6-12 months. Based on a 2026E EPS of CNY 0.46 and applying a sector-appropriate P/E multiple of 25-30x (considering growth and leadership), a fair value range could be CNY 11.5 - CNY 13.8 for 2026 earnings visibility, but given the 2027 EPS of CNY 0.84, forward-looking valuations support higher levels. Note: Investors should focus on the trend of earnings revision and multiple expansion as the cycle turns.

Investment View

Strategic Allocation Recommendation

For institutional investors, Flat Glass represents a classic cyclical recovery play with a strong secular growth backdrop. The investment case is built on three pillars:

1. Bottom-Fishing Opportunity: The worst of the earnings decline is likely behind us. 1H25 results, while weak, confirm the trough. Q2 sequential profit growth and strong cash flow are early signs of stabilization. Investing now allows investors to position ahead of the expected earnings recovery in 2H25 and 2026.
2. Quality Leader in a Fragmenting Market: As weaker players exit, Flat Glass is poised to capture a larger share of a healthier, more profitable market. Its cost advantage ensures it remains profitable even at lower price levels, providing a safety margin.
3. Global Diversification Hedge: The strong performance of the Vietnam subsidiary provides a hedge against domestic Chinese market saturation and trade risks. This global footprint is a key differentiator from purely domestic peers.

Key Monitoring Indicators

Investors should track the following metrics to validate the investment thesis:

• PV Glass Prices: Weekly/Monthly price data for 2.0mm and 3.2mm coated glass. Sustained prices above CNY 12/m² are critical for margin recovery.
• Industry Operating Rates: SMM or other industry data on monthly operating rates. A rate below 60% indicates continued supply discipline; a rapid rise above 70% could signal impending oversupply.
• Inventory Levels: Industry inventory days. A trend below 20 days is bullish; a rise above 25 days is bearish.
• Flat Glass Quarterly Margins: Gross margin trends in Q3 and Q4 2025. Improvement towards 16-17% would confirm the recovery.
• Overseas Revenue Mix: Continued growth in the percentage of overseas revenue and maintenance of >18% gross margins in this segment.
• Capital Expenditure: Discipline in capex. Avoidance of aggressive new capacity additions until prices are sustainably higher.

Conclusion

Flat Glass Group is navigating a challenging industry cycle with resilience and strategic foresight. The 1H2025 results, while reflecting the depth of the industry downturn, also highlight the company’s operational strengths—particularly in cash flow management and overseas profitability. With the PV glass supply-demand格局 (pattern) improving and prices rebounding from historic lows, we believe the company is well-positioned for a profitability recovery in the second half of 2025 and beyond.

We recommend investors accumulate positions on weakness, viewing the current valuation as an opportunity to buy a high-quality industry leader at a cyclical low. The path to recovery may be gradual, but the direction is clear. Flat Glass remains a top pick in the PV materials sector for long-term institutional portfolios seeking exposure to the global energy transition.

Appendix: Detailed Financial Analysis

1. Income Statement Deep Dive

Key Observation: The operating leverage effect is significant. A small increase in revenue and gross margin in 2026-2027 leads to a disproportionate increase in operating profit and net profit. This underscores the attractiveness of the stock as the cycle turns.

2. Balance Sheet Strength

Key Observation: The reduction in long-term debt in 2025E (from CNY 11.0bn to CNY 7.6bn) is a crucial de-risking event. It lowers interest expenses and improves financial flexibility.

3. Cash Flow Sustainability

Key Observation: The positive investing cash flow in 2025E is unusual for a growth company and likely reflects a significant pause in capital expenditure and/or disposal of non-core assets. This conserves cash during the downturn. The return to negative investing CF in 2026-2027 signals renewed investment for growth.

4. Valuation Metrics Comparison

Interpretation:
* P/E: The high 2025E P/E is a artifact of low earnings. The forward P/E of 19.8x in 2027 is attractive for a company with 82% net profit growth in that year.
* P/B: The stable P/B around 1.6-1.8x suggests the market values the company’s asset base consistently. A P/B below 1.5x would historically be a strong buy signal for Flat Glass.
* EV/EBITDA: This metric is less distorted by depreciation and amortization. The decline from 5.1x in 2024 to 3.5x in 2027 indicates improving enterprise value relative to cash earnings power.

Final Remarks

The PV industry is a cornerstone of the global energy transition. While it is prone to cyclical volatility, the long-term demand trajectory remains upward. Flat Glass Group, with its robust cost structure, technological leadership, and global footprint, is well-equipped to navigate these cycles. The current period of industry consolidation presents a strategic opportunity for investors to acquire a leading asset at a reasonable valuation. We reaffirm our Buy-A rating and encourage investors to monitor the upcoming quarterly reports for confirmation of the profitability recovery trend.
