Gross Margin
毛利率
The share of each sale left after the direct cost of making the product. It shows pricing power before overheads, marketing and tax.
每笔销售扣除直接生产成本后剩下的比例，反映管理费用、营销和税之前的定价能力。In This Case 本例中Gross margin was 16.54% for the period to 30 Jun 2026 中报. Direction matters more than level, and a widening lead over peers signals a durable advantage.
方向比水平更重要，与同业差距持续拉大说明优势稳固。

净利率
The share of revenue left as profit after all costs, interest and tax.
扣除全部成本、利息和税后，营收中剩下的利润比例。In This Case 本例中Net margin was −6.32% for the period to 30 Jun 2026 中报, a net loss of ¥1,357.8万 on ¥2.15亿 of revenue. Compare within one industry, because a supermarket at 3% can be healthier than a software company at 15%.
只在同行业内比较：3% 的超市可能比 15% 的软件公司更健康。

持续 15% 以上为佳，前提是不靠高负债撑起来。

Debt Ratio
资产负债率
Total liabilities as a percentage of total assets. At 60%, lenders have funded three yuan of the business for every two from the owners.
总负债占总资产的百分比。60% 意味着贷款方每出三元，股东出两元。In This Case 本例中Total liabilities were 39.23% of total assets at 30 Jun 2026 中报. Read it against the industry, as a bank sits above 90% and a distiller below 30%.
要对照行业来看：银行常在 90% 以上，白酒企业则在 30% 以下。

如果连续多期明显低于净利率，说明销售确认快于回款。
