Buybacks and a battery bet, but profit collapse weighs on Olympic Circuit

Company buyback and shareholder halt to selling Olympic Circuit said it will spend 200-300 million yuan buying back its own shares for staff incentives, and a big shareholder holding 20.11% scrapped a planned share sale. Buybacks shrink the shares in circulation and signal management thinks the stock is cheap, both supporting the price.
The buyback and cancelled reduction are the period's main company-specific supports for the stock.
Buyback executed fast, part of a market-wide wave Olympic Circuit finished nearly 300 million yuan of buybacks in just two trading days, part of a record July for Shanghai-listed buyback and insider-buying plans. Fast execution puts real money behind the promise and lifts sentiment toward the stock.
It shows the buyback was actually carried out, not just announced, reinforcing the capital support story.
70 million yuan stake in power battery connector maker A subsidiary is paying 70 million yuan for a 19.7% stake in Bolati (Platide), which makes connection systems inside electric-car battery packs. The move pushes Olympic Circuit beyond plain circuit boards into the EV supply chain, a growth story investors tend to reward.
This is the period's main new business expansion and a reason for optimism beyond buybacks.
AI demand lifts the sector, but profit fell 78% Lenovo's record AI-driven results sent circuit-board shares, including Olympic Circuit, limit-up on hopes of more orders. Days later, interim net profit came in 78% lower with gross margin down sharply, a serious counterweight to the upbeat buyback and expansion news.
It captures both the demand tailwind and the profit collapse that define the period's real picture.

Ronbay Swings to Profit, Expands Sodium-Ion Capacity

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.
It provides a balanced view of the competitive and pricing risks from collective expansion.
