Over the past three years, its cash dividends have amounted to 134.77% of average annual net profit. Langbo also plans to increase dividend frequency to enhance investor appeal. Coupled with the overall strength of the NEV sector and strong capital inflows, these factors propelled the stock to its daily limit up.
