Aon saw total group revenues increase 16% year-on-year to $2.9bn (£2.08bn) in Q2 FY21, including organic revenue growth of 11%.
Operating income also widened 13% during the three months ended 30 June 2021, up from $594m (£427m) in FY20 to $672m (£483m) the following year.
The quarter also saw Aon repurchase 1.1 million class A ordinary shares at roughly $240m (£172m), while the group’s quarterly cash dividend jumped 11% to $0.51 (£0.37) per share.
Greg Case, CEO at the company, said: “In the second quarter, our team delivered 11% organic revenue growth, our strongest growth in over a decade, that translated into 17% growth in earnings per share, and contributed to 13% free cash flow growth for the first half.
“These results demonstrate the incredible resilience of our colleagues and the power of Aon United. We are moving forward at an accelerated pace, with a proven leadership team and an enduring strategy.”
He added: “Our ability to innovate on behalf of clients remains unrivaled and continues to translate into significant progress against key financial metrics and shareholder value creation.”
Since the period end, Aon has ended its proposed merger with Willis Towers Watson, requiring the group to pay a $1bn (£718m) termination fee.
