What improved

  • Revenue increased 6.4% versus the comparable filing period.
  • Operating margin improved 3.2 percentage points.
  • Net income increased 25.6% versus the comparable filing period.

What weakened

  • Operating cash flow covered only 0.35x net income.

Filing receipts

The increase was due to gains related to the sale of businesses and a decrease in non-cash pension expense.

Operating expenses increased $51 million, or 2%, compared to the prior-year period, due primarily to the increase in expense associated with 5% organic revenue growth and investments in long-term growth, as well as the unfavorable impact of foreign currency translation, partially offset by lower expenses associated with the sale of the NFP Wealth business and $25 million of net restructuring savings. ◦ Risk Capital operating expenses increased $126 million, or 6%, compared to the prior-year period; and ◦ Human Capital operating expenses decreased $46 million, or 4%, compared to the prior-year period.

The increase in adjusted operating margin reflects organic revenue growth, net restructuring savings and tailwinds from currency movements, partially offset by increased expenses associated with 5% organic revenue growth and lower fiduciary investment income. ◦ Risk Capital adjusted operating margin increased to 42.0% in the first quarter of 2026 compared to 41.3% in the prior-year period. ◦ Human Capital adjusted operating margin decreased to 34.4% in the first quarter of 2026 compared to 35.3% in the prior-year period.
