I did some research on Regeneron, these were my findings:

Gross Profit Margin: 91.68%
Net Profit Margin: 18.43%
ROE: 22.10%
Current Ratio:3.75
ROC: 35.21%
Gross profit margin is a very high number. It almost gets to 1. It means that the company is doing great and efficient, making a lot of profit on what it has spent. Current ratio indicates the company may not be efficiently using its current assets or its short-term financing facilities. This may also indicate problems in working capital management.The net profit margin is in a decent area. Overall, the company is in a good financial strength with good growth and profitability.
