• Total operating revenue YoY growth rate (92.31%): Score 2.00, pointing to strong top-line growth but without a clear positive impact on stock price.
• Cost of sales ratio (70.66%): Score 2.00—this high margin pressure could limit profitability.
• PB-ROE: -0.69: Score 1.00, indicating weak performance in relation to book value and return on equity.
