Executive Summary

GoodWe Technologies Co., Ltd. ("GoodWe" or the "Company") has released its financial results for the first half of 2025 (1H25), demonstrating a robust recovery trajectory, particularly within its energy storage segment. The Company reported total revenue of CNY 4.09 billion in 1H25, representing a year-over-year (YoY) increase of 30%. While the net profit attributable to shareholders remained slightly negative at CNY -17 million, this represents a significant 30% improvement YoY, signaling a turnaround from the losses incurred in the previous cycle. The second quarter (2Q25) emerged as a pivotal inflection point, with quarterly revenue reaching CNY 2.2 billion (up 9% YoY and 17% quarter-over-quarter [QoQ]) and net profit turning positive to CNY 11 million (up 129% YoY and 141% QoQ).

The core investment thesis for GoodWe rests on the accelerating momentum in its energy storage business, which is transitioning from a niche contributor to a primary growth engine. In 2Q25, energy storage shipments surged approximately two-fold QoQ, driven by strong demand in key overseas markets, particularly Australia. Looking ahead to the third quarter (3Q25), management guidance and channel checks suggest that storage shipments will more than double QoQ, underpinned by robust household storage demand. Concurrently, the grid-tied inverter business remains stable, with domestic market share consolidating and overseas mix improving, providing a steady cash flow base.

Despite the top-line recovery, profitability margins are still navigating headwinds from rigid operating expenses and competitive pricing pressures. Consequently, we have adjusted our earnings forecasts for 2025 downward to reflect higher-than-expected period expenses, while maintaining our projections for 2026 and 2027 as the company scales into higher-margin storage segments and achieves operational leverage. We estimate the Company’s net profit attributable to shareholders will reach CNY 265 million in 2025, CNY 502 million in 2026, and CNY 702 million in 2027. This translates to a compound annual growth rate (CAGR) that justifies the current valuation multiple, especially considering the projected return to double-digit ROE by 2026.

We maintain our BUY rating on GoodWe. The stock offers an attractive entry point for institutional investors seeking exposure to the global residential energy storage recovery, backed by a diversified product portfolio and strengthening balance sheet metrics. The anticipated surge in 3Q25 storage volumes serves as a near-term catalyst that could re-rate the stock as visibility on earnings quality improves.

Key Takeaways

1. Financial Performance: A Clear Inflection Point in 2Q25

The 1H25 financial results underscore GoodWe’s resilience amidst a challenging macroeconomic environment for the solar industry. The transition from loss to profit in 2Q25 is a critical signal of operational stabilization.

Revenue and Profitability Analysis

• 1H25 Overview: Total revenue stood at CNY 4.09 billion, up 30% YoY. The net loss narrowed significantly to CNY -17 million, a 30% YoY improvement. This indicates that while the Company is still absorbing historical costs and investing in growth, the bleeding has stopped, and the path to sustainable profitability is clear.
• 2Q25 Breakdown:
  • Revenue: CNY 2.2 billion. This represents a 9% YoY increase and a 17% QoQ increase. The sequential growth outpaces the modest YoY growth, suggesting that demand conditions improved markedly in the spring/summer season compared to the winter slowdown typical in 1Q.
  • Net Profit: CNY 11 million. The swing from a loss in 1Q to a profit in 2Q (141% QoQ increase) highlights the operating leverage inherent in GoodWe’s business model. As fixed costs are spread over higher shipment volumes, marginal profitability improves rapidly.

(Note: 1H24 and 2Q24 figures derived from reported YoY/QoQ percentages and 1H25/2Q25 actuals for illustrative context.)

The stability in gross margins during 2Q25, despite the shift in product mix towards storage (which historically carries different margin profiles than inverters), suggests effective cost management and pricing power in key markets. The slight decline in storage margins noted in the report is offset by the volume gains, resulting in an overall flat gross margin profile for the quarter.

2. Business Segment Dynamics: Storage Leads the Charge

The divergence between the grid-tied inverter business and the energy storage business is the defining characteristic of GoodWe’s current cycle. While inverters provide stability, storage provides the alpha.

A. Grid-Tied Inverters: Stability and Geographic Shift

• Shipment Volume: In 1H25, GoodWe shipped approximately 400,000 units of grid-tied inverters. Specifically, 2Q25 saw shipments of roughly 190,000 units. Although this represents a slight sequential decline from 1Q25, it is important to contextualize this within seasonal trends and inventory digestion cycles.
• Geographic Mix: A notable strategic shift is occurring in the geographic distribution of sales. In 2Q25, domestic (Chinese) shipments accounted for 105,000 units, or 55% of the total. This represents a sequential decrease in the domestic proportion, implying that overseas shipments gained share. This is a positive development for long-term margin health, as overseas markets typically offer better pricing and profitability than the highly competitive domestic Chinese market.
• Outlook for 2H25: Demand for grid-tied inverters remains robust. Production schedules for 3Q25 indicate an average monthly output of 80,000–90,000 units. Based on this run rate, we project 3Q25 shipments to grow slightly QoQ. For the full year 2025, we forecast total grid-tied inverter shipments to reach 800,000–900,000 units, representing a substantial >50% YoY growth. This volume growth is essential to absorb fixed manufacturing costs and support the broader ecosystem sales.

B. Energy Storage Systems: The High-Growth Engine

The energy storage segment is experiencing exponential growth, driven by the global transition towards self-consumption and backup power solutions in residential sectors.

• Shipment Surge:

  • 1H25: Total storage shipments reached ~33,000 units.
  • 2Q25: Shipments jumped to ~25,000 units. This is a nearly 2x QoQ increase, demonstrating the rapid scaling of the business.
  • 3Q25 Forecast: Driven by exceptionally strong demand in the Australian market—a key stronghold for GoodWe’s residential storage solutions—we expect shipments to continue their upward trajectory. Our model projects a >100% QoQ increase in 3Q25 shipments. The Australian market’s favorable policy environment and high electricity prices continue to drive robust household adoption rates.
  • Full Year 2025 Forecast: We anticipate total annual storage shipments to land in the range of 150,000–200,000 units. This would represent a >200% YoY growth rate, firmly establishing storage as a core pillar of GoodWe’s revenue base.

• Storage Battery Integration:

  • GoodWe is not merely an inverter manufacturer but an integrated energy solution provider. In 1H25, the Company shipped approximately 214 MWh of storage batteries.
  • In 2Q25 alone, battery shipments reached ~150 MWh, indicating that the majority of the half-year’s battery volume was delivered in the second quarter. This aligns with the surge in complete storage system shipments.
  • Margin Profile: The gross margin for storage batteries remained healthy at approximately 35% in 2Q25. This is a critical metric, as battery margins can be volatile due to raw material (lithium carbonate) price fluctuations. The stability at 35% suggests effective supply chain management and potentially favorable procurement contracts.
  • Full Year Battery Outlook: We project battery shipments to double from 1H levels, reaching >0.5 GWh for the full year 2025. This scale-up will further enhance the Company’s ability to negotiate better terms with cell suppliers, potentially protecting or even expanding margins in 2026.

C. Residential PV Systems: Steady Contributor

• Performance: The residential PV system business (likely including mounting structures, optimized kits, or EPC-related services) sold approximately 0.65 GW in 1H25, a >50% YoY increase.
• Forecast: For the full year 2025, we estimate shipments to exceed 1 GW, representing a slight YoY increase. While not the highest growth segment, it provides a stable, recurring revenue stream that complements the inverter and storage offerings, allowing for bundled sales strategies that increase customer stickiness.

3. Operational Efficiency and Balance Sheet Health

While top-line growth is encouraging, institutional investors must scrutinize the efficiency of this growth and the underlying financial health.

Expense Management

• Period Expenses: In 2Q25, total period expenses (selling, general, administrative, and R&D) amounted to CNY 400 million. This is an 11% increase YoY and an 11% increase QoQ.
• Expense Ratio: The period expense ratio stood at 18.0% in 2Q25.
  • YoY: Increased by 0.4 percentage points.
  • QoQ: Decreased by 1.1 percentage points.
  • Analysis: The sequential improvement in the expense ratio is a positive sign, indicating that revenue growth is beginning to outpace the growth in operating expenditures. However, the YoY increase reflects the "rigid" nature of certain costs, particularly R&D and international sales network expansion, which do not scale down easily during temporary downturns. As revenue scales further in 2H25, we expect this ratio to compress further, driving operating leverage.

Working Capital and Cash Flow

• Inventory Levels: At the end of 2Q25, inventory stood at CNY 2.18 billion, essentially flat compared to the end of 1Q25.
  • Implication: In a growing business, flat inventory while revenue increases QoQ is a positive indicator of inventory turnover efficiency. It suggests that the Company is not building up excess stock in anticipation of uncertain demand but is rather matching production closely with sales orders. This reduces the risk of inventory write-downs in a rapidly evolving technology sector.
• Contract Liabilities: Contract liabilities (advance payments from customers) decreased by 14% QoQ to CNY 380 million at the end of 2Q25.
  • Interpretation: A decline in contract liabilities can sometimes signal weakening order books. However, given the strong shipment growth in 2Q, this likely reflects the conversion of prior quarters' backlogs into recognized revenue rather than a sudden drop in new orders. Monitoring this metric in 3Q will be crucial to confirm sustained demand.
• Operating Cash Flow: A standout metric for 2Q25 was the operating net cash flow of CNY 210 million.
  • YoY Comparison: This represents an increase of CNY 400 million compared to the same period last year.
  • Significance: Positive and growing operating cash flow is the ultimate validator of earnings quality. It demonstrates that the reported revenue growth is backed by actual cash collections, reducing reliance on external financing and strengthening the Company’s liquidity position for future investments.

4. Revised Financial Forecasts and Valuation

Based on the 1H25 results and our updated assumptions for the remainder of 2025, we have refined our financial model.

Earnings Adjustments

• 2025 Estimate Downgrade: We have lowered our 2025 net profit attribution forecast from CNY 350 million to CNY 265 million.
  • Rationale: This adjustment primarily accounts for the rigid growth in operating expenses observed in 1H25. While revenue is recovering, the cost base has proven stickier than initially anticipated. Additionally, we have factored in slight margin pressure in the storage segment due to competitive dynamics, although this is partially mitigated by volume.
• 2026-2027 Estimates Maintained: We maintain our forecasts for 2026 (CNY 502 million) and 2027 (CNY 702 million).
  • Rationale: We believe the expense ratio improvements will accelerate in 2026 as the revenue base expands significantly. Furthermore, the expected mix shift towards higher-value integrated storage solutions should support margin expansion. The long-term structural growth drivers remain intact.

Growth Trajectory

• Net Profit Growth:
  • 2025E: +529% YoY (recovering from a loss base in 2024).
  • 2026E: +89% YoY.
  • 2027E: +40% YoY.
• Revenue Growth:
  • 2025E: +37% YoY.
  • 2026E: +19% YoY.
  • 2027E: +19% YoY.

Valuation Metrics

At the current price of CNY 50.26, the valuation multiples are as follows:

• P/E Analysis: The 2025E P/E of 46x may appear elevated compared to mature manufacturing peers. However, this multiple is justified by the high growth rate (>500% earnings recovery) and the strategic positioning in the high-growth energy storage sector. More importantly, the forward P/E drops rapidly to 24.3x in 2026 and 17.4x in 2027. For a company delivering ~40-90% earnings growth in those years, a 24x multiple is reasonable, and a 17x multiple is attractive.
• ROE Recovery: The Return on Equity (ROE) is projected to rebound from -2.25% in 2024 to 8.79% in 2025, and further to 14.27% in 2026. An ROE above 14% is indicative of a healthy, efficient business capable of generating value for shareholders. The trend suggests that GoodWe is returning to its historical standards of capital efficiency.
• P/B Ratio: The Price-to-Book ratio is trending downward from 4.43x to 2.89x by 2027, reflecting the accumulation of retained earnings and book value growth, making the stock increasingly attractive on a fundamental asset basis.

Risks / Headwinds

While the outlook is positive, institutional investors must consider the following risks that could impact the investment thesis:

1. Intensifying Competition

The energy storage and inverter markets are becoming increasingly crowded.
* Price Wars: In the domestic Chinese market, competition is fierce, leading to potential margin erosion. If this competitive intensity spills over into overseas markets (particularly Europe and Australia), GoodWe may face pressure to lower prices to maintain market share, impacting the gross margins we have modeled.
* New Entrants: Large conglomerates and new specialized startups are entering the residential storage space, potentially fragmenting the market and increasing customer acquisition costs.

2. Demand Uncertainty

• Policy Dependence: The residential storage boom, particularly in key markets like Australia and parts of Europe, is heavily influenced by government subsidies, feed-in tariff adjustments, and net metering policies. Any adverse regulatory changes could dampen demand unexpectedly.
• Macroeconomic Factors: High interest rates in major economies can suppress residential capital expenditure. If mortgage rates remain elevated, homeowners may delay investments in solar and storage systems, affecting shipment volumes in 2H25 and beyond.
• Inventory Corrections: If distributors in overseas markets have overstocked during the previous cycle, a period of destocking could lead to short-term volatility in orders, even if end-user demand remains stable.

3. Supply Chain and Cost Volatility

• Raw Material Prices: While lithium prices have stabilized, any sudden spike in battery raw material costs could squeeze the 35% gross margin currently enjoyed in the battery segment.
• Geopolitical Tensions: Trade barriers, tariffs, or supply chain disruptions related to geopolitical tensions (e.g., between China and Western markets) could impact export capabilities or increase compliance costs.

4. Execution Risk

• Expense Control: Our thesis relies on the assumption that operating expenses will grow slower than revenue in 2026-2027. If the Company fails to achieve this operating leverage due to inefficient expansion or unexpected cost inflation, profitability targets may be missed.
• Technology Shifts: The energy storage technology landscape is evolving rapidly (e.g., solid-state batteries, new chemistries). Failure to keep pace with technological advancements could render current product lines less competitive.

Rating / Sector Outlook

Sector Context: The Global Energy Storage Supercycle

The broader renewable energy sector is undergoing a structural shift from pure generation (solar/wind farms) to integrated generation-plus-storage systems.
* Residential Storage: This segment is experiencing a "second wind" driven by energy security concerns and grid instability in various regions. Australia, in particular, has one of the highest penetrations of rooftop solar globally, creating a natural and urgent demand for behind-the-meter storage to manage grid congestion and maximize self-consumption.
* Inverter Market: The inverter market is maturing, with growth shifting from volume-driven to value-driven (smart inverters, grid-forming capabilities). Companies that can bundle inverters with storage and software services are gaining a competitive moat.

GoodWe’s Positioning

GoodWe is well-positioned to capitalize on these trends.
* Brand Strength: It has established a strong brand presence in key residential markets, particularly in Europe and Australia.
* Product Portfolio: Its comprehensive offering (inverters + batteries + monitoring systems) allows for cross-selling and higher customer lifetime value.
* Agility: Compared to larger, more bureaucratic competitors, GoodWe has demonstrated agility in adapting to market changes, as evidenced by the rapid ramp-up in storage shipments in 2Q25.

Investment Rating: BUY (Maintained)

We maintain our BUY rating. The recent pullback in earnings expectations for 2025 is already reflected in the current price, which trades at a forward P/E that discounts significant future growth. The catalysts for the next 6-12 months are clear:
1. 3Q25 Shipment Data: Confirmation of the projected doubling in storage shipments.
2. Margin Expansion: Evidence of operating leverage in 2H25 reports.
3. 2026 Visibility: As the company guides for 2026, the expectation of >80% earnings growth will likely attract growth-oriented capital.

For long-term institutional portfolios, GoodWe offers a balanced exposure to the renewable energy transition with a specific, high-alpha bet on the residential storage boom. The risk-reward profile is favorable given the substantial downside protection provided by its established inverter business and the upside potential from its scaling storage division.

Investment View

Core Investment Logic

1. The "Storage Second Curve" is Realizing Faster Than Expected
The most compelling argument for investing in GoodWe today is the validation of its storage strategy. Many inverter manufacturers have attempted to pivot to storage, but few have achieved the scale and margin profile that GoodWe is demonstrating. The 2x QoQ growth in 2Q25 and the projected >2x growth in 3Q25 are not just statistical anomalies; they reflect a structural capture of market share in high-value regions like Australia. This "second curve" is moving from the experimentation phase to the mass-adoption phase, which typically commands higher valuation multiples.

2. Operational Leverage Will Drive Earnings Beats in 2026
While 2025 is a year of recovery and reinvestment, 2026 shapes up to be a year of profit explosion. Our model predicts an 89% increase in net profit for 2026. This is driven by two factors:
* Fixed Cost Absorption: The significant increase in shipment volumes (800k+ inverters, 150k+ storage units) will spread fixed R&D and SG&A costs over a much larger revenue base, causing the expense ratio to drop below 18%.
* Mix Shift: As storage becomes a larger percentage of total revenue, and assuming battery margins remain stable or improve due to scale, the blended gross margin of the Company should expand. The current 24-25% gross margin forecast for 2025-2026 has room to upside if premium storage products gain traction.

3. Strong Cash Flow Generation De-risks the Balance Sheet
The generation of CNY 210 million in operating cash flow in 2Q25 is a critical de-risking factor. It proves that the Company is not funding its growth through excessive debt or dilutive equity raises. The flat inventory levels despite revenue growth indicate disciplined working capital management. This financial health provides GoodWe with the flexibility to invest in R&D for next-generation products (e.g., higher voltage systems, AI-driven energy management) without compromising financial stability.

Strategic Recommendations for Investors

• Accumulate on Weakness: Given the volatility inherent in the solar/storage sector, any short-term market corrections driven by broader macro fears rather than company-specific fundamentals should be viewed as buying opportunities. The long-term trajectory of earnings growth (CAGR >40% from 2025-2027) supports a higher intrinsic value.
• Monitor 3Q25 Guidance: The key near-term catalyst is the 3Q25 performance. Investors should closely watch monthly shipment data and channel checks from Australia and Europe. If the projected doubling of storage shipments materializes, it will confirm the sustainability of the growth trend.
• Focus on Margin Trends: While revenue growth is impressive, the key to sustained stock appreciation will be margin expansion. Watch for commentary on battery raw material costs and pricing power in overseas markets. Any sign of margin resilience in the face of competition will be a strong positive signal.

Comparative Valuation Perspective

When compared to peers in the global inverter and storage space, GoodWe’s valuation is becoming increasingly attractive on a forward-looking basis.

• Vs. Pure Inverter Plays: Companies solely focused on grid-tied inverters are facing slower growth and margin compression due to saturation. GoodWe’s diversification into storage gives it a premium.
• Vs. Integrated Storage Giants: Larger players may have scale, but GoodWe’s focus on the residential segment allows for higher agility and potentially higher margins per unit in niche markets. The projected 2026 P/E of 24x is competitive against global peers trading at 25-30x for similar growth profiles.

Conclusion

GoodWe (688390.SH) is executing a successful turnaround strategy, pivoting from a pure inverter manufacturer to a leading residential energy storage solutions provider. The 2Q25 results confirm that this pivot is gaining momentum, with storage shipments accelerating and profitability returning. While near-term expenses remain rigid, the path to significant operating leverage in 2026 is clear.

We believe the market is underestimating the speed and scale of GoodWe’s storage growth. With a robust balance sheet, improving cash flows, and a dominant position in key overseas markets, GoodWe is well-equipped to deliver superior shareholder returns over the next three years. We reiterate our BUY rating, with a target valuation framework supported by 2026 earnings potential.
