First-half profit turnaround Ronbay returned to profit with 109 million yuan net income, versus a loss last year, as revenue rose 39.57% on higher shipments and better overseas plant use. This shows the core business is recovering, which supports the stock price.
This is the key financial result that directly improves investor confidence and valuation.
Sodium-ion cathode expansion Ronbay plans to invest 4.723 billion yuan in a 300,000-tonne sodium-ion cathode plant, with first phase starting August 2026. Sodium-ion products are already shipping at scale, positioning the company for future growth beyond lithium.
This major investment signals a new growth engine and long-term capacity leadership.
Lithium manganese iron phosphate full production The company's LMFP business is running at full capacity with all output sold, and sales rose about 50% year-on-year. This high-demand product line boosts revenue and shows strong market acceptance.
It highlights a key product driving current sales and profitability.
Industry-wide capacity expansion risk Rising material prices have triggered about 30 billion yuan of new projects across the battery supply chain, including Ronbay's. While this meets current demand, it could lead to oversupply and margin pressure later, a risk to watch.
