Evercore ISI analyst David Motemaden upgraded Aon plc (AON) to Outperform from In Line with a price target of $420, up from $407. Following two years of relative underperformance, the firm sees upside to organic growth driving positive earnings revisions and multiple support, the analyst tells investors. The firm sees a return in M&A and capital markets activity, improving retention and increasing contributions from new hires helping Aon re-rate higher, the analyst added.
