Earning Per Share


Financial analysis from Q1 2019 to Q1 2020 indicates a mixed picture. Working capital efficiency shows a slight decrease in liabilities and current assets on revenue.  Cost efficiency demonstrates a decrease in SG&A expense ratio but with substantial volatility.  Importantly, there's a substantial increase in the ratio of retained earnings to revenue and retained earnings on assets, signifying possible improvements in profitability and investment efficiency, but more data is needed to confirm this. The significant fluctuations warrant further investigation into the underlying factors.
