Arthur J. Gallagher & Co.AJG

Arthur J. Gallagher executed a staggering $13.8 billion cash buyout of AssuredPartners in FY2025, a transaction size that dramatically accelerates its global roll-up strategy. The central investment thesis for this insurance heavyweight relies on its proven capacity to ingest massive targets without fracturing the underlying profitability of its core operations.

This acquisitive engine has steadily compounded shareholder value, as diluted earnings per share expanded from $4.37 in FY2021 to $6.50 by the end of FY2024. The company routinely absorbs dozens of regional peers annually, culminating in a FY2025 where the core brokerage unit drove 87% of overall revenues while posting a 36.5% adjusted EBITDAC margin—an improvement of 145 basis points year-over-year. To finance its latest mega-deals, management tapped capital markets aggressively in late FY2024, floating $5 billion in senior notes and securing $8.5 billion through a massive equity offering. Despite the resulting share dilution, the firm still returned $674 million to investors via dividends in FY2025.

The market has heavily rewarded this execution of scale and margin discipline. At the close of FY2025, the stock traded at $258.79, reflecting investor confidence in the company's ability to synthesize a sprawling international footprint—which now accounts for 33% of total revenues—into sustained cash flow.
