Jefferies analyst Hamzah Mazari initiated select names across the Environmental Services sector as part of his broader research note covering the Business Services industry. The analyst has a Buy rating on Republic Services (RSG), Waste Connections (WCN), and Casella Waste (CWST) with respective $100, $106, and $52 price targets. Mazari notes that the higher landfill pricing stands to benefit Republic Services given its growth-positioned asset base and also believes that the strong portfolio mix support Waste Connections and Casella Waste. The analyst rates Clean Harbors (CLH) with Underperform and a price target of $75 with concerns that its current mix benefits of growth in 70% of its revenue base look unsustainable. Mazari rates Stericycle (SRCL), Waste Management (WM), and Covanta (CVA) at Hold with $68, $120, and $16 price targets and respective views of volume growth being priced in to valuation, limited visibility on medical waste portfolio rationalization, and uncertainty around pricing recovery in power/metals.
