On September 4th, Gelonghui reported that China's leading lens company, Mingyue Lens (301101.SZ), once fell by more than 8% during trading, and is now trading at 24 yuan, with a total market value of less than 5 billion yuan. The company's semi-annual report for 2024, released earlier, showed that although the company's revenue and net profit achieved double-digit growth, the growth rate has slowed significantly, marking the slowest half-year growth since the company went public. At the same time, the company's high receivables cannot be ignored, with four customers making full provisions for bad debts, and issues such as a focus on sales over research and development, as well as persistently high sales expenses, still persist.
