Because there are many ways to measure a company's success, here are the most successful companies in the U.S. as measured by five different metrics. The metrics are Sales, Profits, Shareholder Returns, Quality of Workplace, and Carbon Footprint. Data for Sales, Profit, and Shareholder Returns are measured over the last 12 months, and Employee Satisfaction and Carbon footprint are as of the most recently available data.. The list will be limited to the S&P 500 as data on these companies are most readily available.

Sales:

Big-box retailer Wal-Mart (WMT) brought in $521 billion in the past 12 months, the most of any company in the S&P 500.

Profits:

Electronics firm Apple (AAPL) has earned $55.3 billion in net income over the past 12-months, more than any company in the S&P 500.

Employee Satisfaction

Hilton Worldwide Holdings (HLT) was rated the best place to work in Fortune Magazine's "100 Best Companys To Work For" survey of 2019. The survey, done by analytics firm, Great Place to Work, surveyed 4.3 million employees with more that 60 survey questions about their workplace.

Carbon Footprint:
