Barclays upgraded Casella Waste to Overweight from Equal Weight with a price target of $102, up from $101. The firm cites the company's "strong" Q1 results and visibility to synergies following the Mid-Atlantic systems integration for the upgrade. While landfill pricing will remain debated, cost savings and incremental acquisition capacity will support estimate upside for Casella, the analyst tells investors in a research note. Barclays expects the company to see a margin inflection.
