Price data through an unavailable date for AJG and an unavailable date for AON. Filing periods shown by the reports are 2026-06-30 and 2026-06-30. Matching report-level filing periods do not prove that every metric covers the same window. The reports use the same financial profile.

Drawdown is the largest fall from a prior peak in the covered history. Annualized volatility describes how widely returns varied; neither measure predicts what happens next.
