Shandong Zhanggu's attributable net profit for 2025 was RMB 63.115 million, a year-on-year decrease of 19.46%, while operating cash flow surged by 619.61%.

The company's revenue and net profit both declined in 2025, with the non-GAAP net profit dropping by 24.27%, putting pressure on core business profitability; operating cash flow surged by 619.61%, but the increase in the sales expense ratio and a sharp rise in financial expenses weighed on the net profit margin; internal control failures led to an adverse opinion being issued, resulting in the imposition of ST status, combined with regulatory penalties, damaging the credibility of ongoing operations.
