Latest analysis: Marsh McLennan Q3 2026: Revenue $6.9B, Adjusted EPS $2.03

Key Figures

Amounts in MUSD (millions of US dollars), exactly as the ledger records them.

What's Inside

<One or two sentences: fiscal year end (and 52/53-week rule or fiscal-year change, if any), SEC CIK or home exchange, and the one structural fact a reader needs — a sector-specific account, a restatement, why history starts where it does.>

Quick Start

uvx --from beancount bean-check main.bean
uvx --from beanquery bean-query main.bean \
  "SELECT year, sum(position) WHERE account ~ '^Income:Revenue' GROUP BY year ORDER BY year"

Zero output from bean-check means the ledger is internally consistent: every
income statement sums to zero and every balance-sheet snapshot reconciles to
the filed totals. The query prints revenue by calendar year; income is a
credit, so it shows as a negative number. Open main.bean in Fava
or import it into beancount.io to explore it visually.

Methodology

• Balance sheet — pad / balance directives assert each period-end
  figure against the filing named in that period file's source banner.
• Income statement — one zero-sum transaction per period: Income
  negative (credit), Expenses positive (debit), with the arithmetic check in
  a comment directly above it.
• Unit — MUSD; 6,863 MUSD means 6,863 million US dollars.

Analysis

• Marsh McLennan Q3 2026: Revenue $6.9B, Adjusted EPS $2.03 — FY2026Q3
