Sunwoda (300207.SZ) Power Battery Business In-depth Analysis Report

Sunwoda Electronic Co., Ltd. is a leading lithium-ion battery module manufacturer in China, with main businesses covering three segments: consumer electronics batteries, power batteries, and energy storage systems. According to the latest market data [0], the company’s current market capitalization is USD 48.7 billion, share price is USD 26.36, corresponding to a price-earnings ratio of 29.06x and a price-to-book ratio of 1.94x. Notably, the company’s share price has experienced significant volatility recently, with a single-day drop of 11.39% and a 23.68% decline in the past three months, indicating that the market has certain concerns about the company’s performance.

From a technical analysis perspective [0], the company’s stock is currently in a sideways consolidation pattern, with a trading range referencing a support level of USD 25.71 and a resistance level of USD 28.96. The KDJ indicator shows a death cross signal (-), the MACD indicator remains in a bullish alignment but without obvious crossovers, and the RSI indicator is in the oversold zone, suggesting a possible short-term rebound opportunity but an unclear medium-term trend.

According to public information and relevant reports, Sunwoda’s power battery business faces severe profitability challenges. In 2023, the power battery business recorded a loss of 1.56 billion yuan; combined with losses from previous years, the cumulative loss over two and a half consecutive years exceeded 4.5 billion yuan, with a gross margin of only 8.8%, far below the healthy industry level (generally, power battery enterprises should maintain a gross margin of more than 15%-20%).

From the perspective of the company’s overall financial indicators [0], the latest quarterly financial report for 2025 shows:

• Net Profit Margin
  : 2.71% (at a low level)
• Operating Profit Margin
  : 1.83% (extremely limited profit margin)
• Free Cash Flow
  : -2.903 billion yuan (tight cash flow situation)
• Current Ratio
  : 1.07 (weak short-term debt repayment ability)
• Quick Ratio
  : 0.87 (insufficient liquidity after excluding inventory)

The earnings per share in the third quarter of 2025 was USD 0.30, lower than the market expectation of USD 0.35, with an unexpected loss margin of 14.94%; revenue was USD 1.655 billion, also lower than the expected USD 1.732 billion, a gap of 4.47% [0]. These data indicate that the company’s overall profitability has not yet achieved fundamental improvement.

The loss phenomenon faced by Sunwoda is not unique. The power battery industry as a whole experienced multiple pressures such as overcapacity, intensified price wars, and raw material cost fluctuations during 2023-2024. Although most power battery enterprises did not separately disclose loss data for power battery businesses, their gross margins in financial reports are generally low, reflecting the impact of cyclical and structural adjustments in the industry.

Over the past few years, the expectation of high growth in the new energy vehicle market has driven large-scale capacity expansion by power battery enterprises. However, since 2024, the growth rate of new energy vehicle sales has slowed down, leading to lower-than-expected demand for power batteries, reduced capacity utilization, and increased pressure on fixed cost amortization. Sunwoda’s capacity layout in the power battery field is relatively aggressive, and the scale effect has not yet been fully released.

Prices of lithium battery raw materials (lithium carbonate, lithium hydroxide, cathode and anode materials, etc.) fluctuated sharply in 2022-2023. Although lithium prices fell in 2024, the digestion of high-priced inventory from earlier periods and the mismatch in pricing cycles with downstream customers compressed profit margins.

The power battery industry has high customer concentration, and downstream vehicle manufacturers have strong bargaining power. As a second-tier power battery supplier, Sunwoda is relatively weak in customer structure and pricing power, making it difficult to effectively pass on cost pressures.

The power battery industry has rapid technological iteration, requiring continuous high R&D investment to maintain competitiveness. Sunwoda’s layout in cutting-edge technologies such as sodium-ion batteries and solid-state batteries takes time to translate into commercial results, contributing little to profits in the short term.

The company should carefully evaluate existing capacity, optimize and integrate or transform production lines with low utilization rates. At the same time, strengthen strategic cooperation with leading vehicle enterprises to lock in stable orders and increase capacity utilization to a reasonable level. Reducing unit costs through scale effects is the basic path to improving gross margins.

Continue to increase R&D investment, focusing on breaking through the following directions:

• Material System Optimization
  : Improve cell energy density and reduce material costs
• Production Process Improvement
  : Increase yield rate and reduce manufacturing costs
• Next-Generation Battery Technology
  : Accelerate the industrialization of solid-state batteries and sodium-ion batteries to seize technological制高点 (high ground)

Establish a more agile raw material procurement mechanism to hedge price fluctuation risks through long-term agreements, hedging, etc. At the same time, promote internal cost reduction and efficiency improvement, optimize production processes, and enhance operational efficiency.

The energy storage business is an important incremental market for power battery enterprises. Sunwoda should increase R&D and market development efforts for energy storage batteries. At the same time, actively layout overseas markets, especially the European and Southeast Asian new energy vehicle markets, to diversify regional risks and obtain incremental orders.

According to market information, Sunwoda is considering spinning off its power battery business for listing in Hong Kong [1]. This move helps:

• Introduce strategic investors and supplement capital
• Improve business transparency and obtain independent valuation
• Concentrate resources on core businesses and improve overall financial structure

1. Intensified Industry Competition
   : Market share concentration of leading enterprises increases, squeezing the survival space of second-tier manufacturers
2. Changes in New Energy Vehicle Policies
   : Policy factors such as subsidy withdrawal and emission standard adjustments affect demand
3. Technological Route Changes
   : Uncertainty in technological routes such as solid-state batteries and sodium-ion batteries
4. Cash Flow Risk
   : Sustained losses may lead to cash flow tension, affecting normal operations

Considering:

• The company’s stock price has risen by 23.29% cumulatively in 2025, and the current valuation is in the middle of the historical range
• Technical indicators suggest a possible short-term rebound opportunity [0]
• Free cash flow remains negative, and financial pressure persists
• The timeline for turning around the power battery business is unclear

Investors are advised to maintain a cautious attitude, focusing on the progress of fundamental improvement and the spin-off of the power battery business. For long-term investors, they can布局 (position) at low prices, but need to set strict stop-loss levels and reasonable profit expectations.
