Arthur J. Gallagher & Co.AJG

Arthur J. Gallagher & Co. recently cemented its status as a relentless consolidation engine by closing a massive $13.8 billion cash acquisition of AssuredPartners in FY2025. This record-setting buyout underscores the core investment thesis for the global insurance broker: an aggressive, debt-and-equity-fueled roll-up strategy that successfully translates rapid inorganic scale into expanding operational profitability. By routinely absorbing dozens of targets annually, the firm continuously deepens its international footprint while pushing margins higher.

The success of this strategy is evident across its long-term financial arc, as diluted earnings per share expanded from $4.37 in FY2021 to $5.74 by the close of FY2025. In FY2025, the company’s primary brokerage unit drove 87% of total revenue and widened its adjusted EBITDAC margin by 145 basis points to reach a highly efficient 36.5%. This robust profitability supported both ongoing acquisitions and direct shareholder returns, including $674 million in dividends paid out over the year. The firm's momentum has only accelerated since, with top-line performance surging 27% year-over-year to reach $4.716 billion in Q1 2026. Investors have aggressively rewarded this execution; at the close of FY2025, the market valued the firm at a $66.5 billion market cap, with shares priced at $258.79 and trading at a premium 45.1x earnings multiple.
