AJG's Organic Growth Resilience Supports Long-Term Expansion
Arthur J. Gallagher's durable organic growth, margin expansion and AssuredPartners integration support its outlook as insurance pricing moderates.
Arthur J. Gallagher & Co. AJG appears well positioned to sustain around 6% organic growth and continue expanding underlying margins even as insurance pricing moderates. However, the mix of growth is likely to shift away from rate-driven growth toward new business, client retention, exposure growth, productivity and acquisitions.
AJG witnessed another solid quarter of organic growth across each business and geography. AJG projects a total company organic outlook of 6%, brokerage at 5.5% and risk management at 9% for 2026. AJG expects 2026 will be another year of excellent organic growth.
For the combined Brokerage and Risk Management segments, growing both organically and through acquisitions delivered total revenue growth of 24% in the second quarter of 2026. Organic growth was 6%, reflecting continued strength across each of the businesses.
The bigger drivers of Organic growth remain new business, strong client retention, exposure growth and the diversity of the model across P/C, benefits, reinsurance and claims. AJG is also gaining from activity across construction, infrastructure, energy and data centers. These areas create new, more complex client needs, requiring more advice, broader capabilities and deeper expertise, which play directly into Arthur J. Gallagher's advisory strengths.
Arthur J. Gallagher recorded its 25th consecutive quarter of double-digit adjusted EBITDAC growth, while management highlighted continued underlying margin expansion. Productivity and quality improvement are among AJG's four long-term strategic pillars.
The acquisition of AssuredPartners is now nearly a year into integration, with management reporting strong retention and good collaboration between teams. As integration progresses, cost synergies and greater scale could support margins.
What About Its Peers?
Brown & Brown, Inc. BRO experienced a moderation in organic growth in the second quarter of 2026, reflecting a softer insurance pricing environment and weakness in its Specialty Distribution business. Organic revenues declined 0.7% year over year, while organic revenues, including contingent commissions, increased 0.7%. Despite the near-term pressure, BRO expects organic growth to improve in the second half of 2026, with management targeting 1.5-2.5% growth in Retail and 2-4% in Specialty Distribution, excluding contingents.
Willis Towers Watson Public Limited Company WTW delivered 5% organic revenue growth in the second quarter of 2026, supported by broad-based momentum across its businesses. WTW achieved this growth despite a competitive insurance pricing environment, with rates declining across most lines. The company's specialization, recurring revenue streams, new-business wins and strong client retention should help sustain mid-single-digit organic growth, while operating leverage and expense discipline provide further support for profitability.
