Im doing a financial anaylys on cvs pharmacy for a period of 5 years

they had 5 consecutive years of positive operating cash flow

they had 5 consecutive years of positive free cash flow

they had 5 years of negative capital spending

and 4 years (consecutive) positive working capital and 1 year of negative working capital

Based on the above does cvs generate enough operating cash flow to reward shareholders and creditors? How is cvs doing if they have postivie cash flow for 5 years and negative capital spending for 5 years
