Arthur J. Gallagher & Co. has acquired Brisbane-based International Insurance Brokers Pty Ltd, an Australian retail broker that places property cover for non-profit organisations. Terms of the transaction were not disclosed. International Insurance Brokers provides retail broking services across Australia, with clients including charities, community groups, and other not‑for‑profit entities that purchase property insurance. The business will be integrated into Gallagher’s existing Brisbane operations, with its staff and client portfolio transitioning to the group’s Australian retail network.
The International Insurance Brokers team, led by Justin McPherson and Vince Mason, will relocate to Gallagher’s Brisbane office. They will report to Alex Lumby, head of retail property/casualty brokerage operations for Gallagher in Australia. “International Insurance Brokers brings strong niche expertise and expands our retail brokerage capabilities in Australia. I am very pleased to welcome Justin, Vince, and their associates to Gallagher,” said J. Patrick Gallagher, Jr., chairman and CEO of Arthur J. Gallagher & Co.
The Brisbane acquisition follows Gallagher’s announcement of fourth-quarter and full-year 2025 financial results, which showed higher revenues in both its brokerage and risk management segments. For the quarter ended Dec. 31, 2025, total company revenues before reimbursements were US$3.59 billion, compared with US$2.68 billion in the fourth quarter of 2024. On an adjusted basis, total company revenues were US$3.57 billion, with adjusted net earnings of US$620 million and adjusted EBITDAC of US$1.05 billion. In the brokerage segment, fourth-quarter revenues before reimbursements were US$3.17 billion, up from US$2.30 billion a year earlier. Adjusted brokerage revenues were US$3.15 billion, with adjusted EBITDAC of US$1.02 billion. The risk management segment reported quarterly revenues of US$417 million, with adjusted EBITDAC of US$90 million.
For the full year to Dec. 31, 2025, Gallagher reported total company revenues of US$13.78 billion, compared with US$11.40 billion for 2024. Adjusted total company revenues were US$13.75 billion, with adjusted net earnings of US$2.79 billion and adjusted EBITDAC of US$4.49 billion. Within brokerage, full-year reported revenues were US$12.19 billion, versus US$9.93 billion in the prior year, with adjusted brokerage revenues of US$12.17 billion. The risk management segment recorded 2025 revenues of US$1.59 billion, with adjusted segment revenues of US$1.58 billion. On an adjusted basis, total brokerage and risk management revenues were US$13.75 billion, with adjusted net earnings of US$3.38 billion and adjusted EBITDAC of US$4.78 billion.
Gallagher’s latest Australian transaction has been announced against a backdrop of weaker overall deal volumes in the wider Asia-Pacific region in early 2026. Data from GlobalData indicates that total APAC deal activity – covering mergers and acquisitions, private equity, and venture financing – declined by about 6% year over year in January–February 2026. Within that total, M&A deal volume in APAC fell by 32% compared with the same period in 2025, while private equity deals more than halved. Venture financing was an exception, with deal numbers increasing by 28% year over year.
“While the growth in venture financing is encouraging, the significant declines in M&A and private equity highlight the challenges facing the APAC deals landscape, reflecting broader economic uncertainties that have dampened deal-making sentiments,” said Aurojyoti Bose, lead analyst at GlobalData. Activity diverged across major markets. China recorded a 47% increase in deal volume in the first two months of 2026, offsetting part of the reduction elsewhere in the region. India, Japan, Australia, and South Korea all saw lower announced deal volumes, with respective declines of 5%, 51%, 17%, and 26%.
