Valuation and analyst target
Aon carried a trailing P/E of 15.01 and a dividend yield of 1.00 percent on October 8, 2026. These figures place the emphasis on earnings delivery and the valuation multiple rather than on the modest 0.50 percent Lang & Schwarz move.
According to Yahoo Finance on October 7, 2026, Mizuho maintained an Outperform rating while lowering its target from USD 366.00 to USD 324.00. The target revision gives investors a dated reference for how analyst expectations have shifted, but it does not change the euro price benchmark used here.
