Waste Management has delivered consistent revenue growth, with 4-quarter revenue increasing from $6.0B in Q4 2013 to $6.3B in the most recent Q4 2022. The company's free cash flow has also remained robust, rising from $2.8B in Q4 2013 to $3.0B in Q4 2022, a 7.1% increase. This strong free cash flow generation has enabled Waste Management to steadily reduce its debt burden, with the debt-to-equity ratio improving from 3.6x in Q4 2013 to 2.9x in Q4 2022. Additionally, Waste Management's net margin has expanded from 10.7% in Q4 2013 to 12.0% in Q4 2022, indicating the company's ability to effectively manage costs and improve profitability. These trends suggest Waste Management is well-positioned to capitalize on the increasing focus on environmental sustainability and waste reduction initiatives, which should drive continued growth in the coming years. Given Waste Management's robust financial performance, improving balance sheet, and exposure to favorable industry tailwinds, I believe the stock is an attractive long-term investment opportunity. The company's consistent revenue growth, expanding net margins, and strong free cash flow generation provide a solid foundation for future value creation.
