The company, on the basis of change in net income from the same quarter one year ago, has significantly underperformed when compared with that of the S&P 500 and the Electric Utilities industry. The net income has significantly decreased by 82.5% when compared with the same quarter one year ago, falling to $6.03 million from $34.45 million. The gross profit margin for the company is rather low; currently it is at 23.20%. It has decreased significantly from the same period last year. Along with this, the net profit margin of 4.20% trails that of the industry average. The decrease in margins is one factor that caused Empresa to experience a steep decline in earnings per share in the most recent quarter. This year, the market estimates earnings will improve to $1.77. Weakness in the company's revenue is the other factor that seems to have hurt the bottom line, decreasing its earnings per share. The revenue fell significantly faster than the industry average of 5.0%. Since the same quarter one year prior, revenues fell by 28.7%. Despite any intermediate fluctuations, we have only bad news to report on this stock's performance over the last year: it has tumbled by 55.78% -- underperforming the S&P 500. Consistent with the plunge in the stock price, the company's earnings per share are down 84.33% compared with the year-earlier quarter. Despite the heavy decline in its share price, this stock is still more expensive (when compared to its current earnings) than most other companies in its industry.
