Dian Diagnostics Group Co.,Ltd.: history, ownership, mission, how it works & makes money

Born in 1996 and listed on the Shenzhen Stock Exchange as 300244 in 2011, Dian Diagnostics Group Co., Ltd. has grown from a Zhejiang lab supplier into an integrated diagnostics player offering laboratory supplies, AI-assisted digital pathology, multi-omics platforms and forensic testing-yet 2024 was a rough chapter: operating revenue fell to 12.196 billion yuan with a net profit attributable to shareholders of -357 million yuan, while high-end specialty testing still accounted for a notable 40.31% of diagnostic services revenue; the company now balances a product business (8.134 billion yuan in 2024) and diagnostic services (4.520 billion yuan in 2024) as it trims headcount and accelerates digital transformation-partnering with Huawei Cloud to launch the "Dian Medical Inspection Big Model"-making this a pivotal moment for investors and industry observers to dig into history, ownership moves, operating segments and the path to restoring profitability
