Waste Management and Republic Services, two major waste management companies, have outperformed the S&P 500 over the past decade by leveraging pricing power, long-term contracts, and sustainability initiatives. Waste Management expanded significantly with its acquisition of Stericycle, while Republic Services focused on acquisitions and environmental solutions. Despite strong 10- and 5-year returns, both companies faced recent headwinds such as integration costs, labor disruptions, and falling recycled commodity prices, leading to modest or negative returns in the past year. Going forward, Waste Management's integration progress and free cash flow growth, along with dividend increases, are key factors to watch, while Republic Services faces risks from commodity price declines but remains operationally strong.
