Arthur J. Gallagher & Co., a global leader in insurance brokerage and risk management services, has announced impressive financial results for the second quarter of 2025. With significant growth in key financial metrics and continued momentum in strategic acquisitions, the company is solidifying its position in the global insurance and risk advisory landscape.
Strong Financial Performance in Q2 2025
In Q2 2025, Gallagher reported a 23% year-on-year rise in adjusted EBITDAC, reaching US$1.01 billion, up from US$821 million in the same period last year. Similarly, adjusted net earnings increased to US$609.1 million, compared to US$511.2 million in Q2 2024. This consistent growth reflects the company’s ability to execute its strategy effectively, even in a shifting economic climate.
Furthermore, diluted net earnings per share on an adjusted basis rose to US$2.33, showing a modest gain from US$2.29 per share in the previous year. This indicates not only profitability but also operational stability and investor confidence.

Brokerage and Risk Management Segments Drive Revenue
Gallagher’s core strength remains its brokerage segment, which posted a 16% jump in revenue to US$2.78 billion. Additionally, adjusted EBITDAC for this segment reached US$1.01 billion, reflecting strong organic and inorganic growth. Notably, the company also recorded 9% revenue growth in its risk management division, which includes its well-known claims management arm, Gallagher Bassett, bringing in US$391.8 million.
Importantly, organic revenue growth across both brokerage and risk management came in at 5.4%. While this is slightly lower than some previous quarters, it’s a solid number in a market that’s increasingly competitive.
Strategic Acquisitions Continue to Fuel Growth
In the second quarter alone, Gallagher completed nine acquisitions, representing an estimated US$290 million in annualised revenue. These acquisitions are in line with the company’s long-standing acquisition strategy, which focuses on expanding geographic reach and deepening its specialty capabilities.
Moreover, the company reaffirmed its commitment to closing the US$13.45 billion AssuredPartners acquisition by Q3 2025. Once finalized, this acquisition will significantly expand Gallagher’s scale in the middle-market segment, enhancing its ability to serve clients across North America and beyond.

Market Insights: P&C Insurance and Global Trends
The global property and casualty (P&C) insurance market remains a mixed bag, according to Gallagher. While property lines have started to soften with average renewals declining by 7%, the casualty side continues to harden, with rates rising 8% on average.
In London, one of the world’s most important insurance hubs, rate momentum has started to level off. Gallagher operates several units in London, including its specialty reinsurance arm Gallagher Re, and has reported intensified competition, particularly in marine, energy, and financial lines. At the same time, brokers are seeing greater scrutiny on casualty treaty renewals and longer placement timelines in cyber and D&O classes.
Nevertheless, Gallagher’s diversified footprint allows it to navigate these complexities. The company’s London operations are especially well-positioned to capitalize on continued demand for reinsurance and wholesale distribution, as clients increasingly look for solutions tailored to inflation-linked risks and complex regulatory challenges.
Leadership’s Strategic Focus
Chairman and CEO J. Patrick Gallagher, Jr. emphasized the company’s impressive streak of growth:
“21 consecutive quarters of double-digit adjusted EBITDAC growth.”
This statement underscores the leadership’s focus on sustained profitability and operational excellence. Gallagher’s management attributes this success to a mix of strategic acquisitions, organic expansion, and an unwavering client-centric approach.
In fact, the leadership remains confident despite ongoing shifts in the global underwriting landscape. Gallagher added:
“While we continue to monitor underwriting appetite shifts in London and globally, our teams are focused on delivering value through specialist expertise and data-driven solutions.”
This long-term vision continues to guide the company’s decisions as it scales globally.

Financial Position and AssuredPartners Deal
As of June 30, 2025, Gallagher held over US$12.8 billion in total debt, following the equity and senior notes issuance to finance the AssuredPartners acquisition. Despite the large investment, the company has remained on track with its financial goals, suggesting disciplined financial management and a clear return-on-investment strategy.
This acquisition, once finalized, is expected to be transformational. It will increase Gallagher’s market share in the U.S. and strengthen its presence in high-growth verticals like healthcare, construction, and employee benefits.
Final Thoughts: Gallagher’s Growth Outlook Remains Strong
Arthur J. Gallagher & Co. continues to shine in a complex and evolving insurance marketplace. From strong Q2 earnings and steady organic growth to strategic acquisitions and global market adaptability, the company shows no signs of slowing down.
While macroeconomic and insurance market challenges remain, Gallagher’s forward-looking approach, seasoned leadership, and deep industry knowledge put it in a favorable position for continued growth throughout 2025 and beyond.
For stakeholders, clients, and investors alike, Gallagher remains a company to watch.
