Tinavi to buy 62% of Shanghai Orthopedics, adding implants to robot business

Tinavi to acquire 62% of Shanghai Orthopedics via share issuance Tinavi will buy a 62% controlling stake in Shanghai Minimally Invasive Orthopedics, a maker of joint implants, using newly issued shares. This fills the missing implant part of its product line, letting it sell robots plus implants together. The stock resumes trading July 30.
This is the core new event that directly changes Tinavi's business and drives the stock.
Deal creates robot-plus-implant synergy and long-term growth potential Combining Tinavi's surgical robots with Shanghai Orthopedics' hip and knee implants should boost sales through shared hospitals and doctors, and speed up new product development. The target's knee implant has a strong 17-year survival rate and sells in the US, Japan and Europe.
Explains why the acquisition could lift future earnings, not just headline news.
Deal is still subject to approvals and due diligence The acquisition is a major restructuring and needs regulatory approvals, due diligence and a formal agreement. It could still fall through. Also, paying with new shares dilutes existing shareholders, though the company says control will not change.
Provides the real counterweight: execution risk and share dilution could cap gains.

Wondfo's first-half profit and cash recovery offset a decade-first annual loss

First loss in a decade as policy squeezes demand and prices Wondfo's 2025 revenue fell 31.91% and it posted its first loss since listing, hit by centralized procurement and DRG/DIP payment rules that cut test volumes and prices. The stock hit a new low, down about 72% from its peak, showing how badly policy pressure hurt the core testing business.
Explains the main force behind the stock's slump and why investors are worried.
Buyback and controlling-shareholder purchases signal insider confidence The company approved a 30-60 million yuan buyback, and controlling shareholder Wang Jihua bought 1.156 million shares for about 20 million yuan, completing her 20-40 million yuan plan. Insiders putting real money in suggests they see the shares as undervalued, which can support the price.
Shows concrete capital actions that counter the negative news and support the stock.
First-half profit and cash flow swing back to positive Wondfo reported first-half 2026 revenue of 1.039 billion yuan and net profit of 123 million yuan, with operating cash flow turning from a 56.31 million yuan outflow to a 423.99 million yuan inflow. Gross margin edged up, and overseas molecular diagnostics revenue jumped 228%, suggesting the worst may be passing.
This is the key new evidence that the business is recovering, directly answering why the stock may be moving.
Seven new chemiluminescence registrations widen product range Wondfo received seven chemiluminescence device registration certificates covering liver, islet and heart tests. These add to its product lineup and support its push into the larger in-vitro diagnostics market, though the company says the revenue impact cannot yet be predicted.
Shows new product momentum that could drive future growth, a fresh positive for the stock.
