Arthur J. Gallagher & Co. will change leadership in its Benefits & HR Consulting division as Tom Doyle succeeds William F. Ziebell as CEO on January 1, 2027. The company announced the transition on November 3, 2026, in a company release carried by PR Newswire.

Arthur J. Gallagher stock traded at 251.40 euros on Lang & Schwarz at 15:32 CET on Monday, November 9, 2026, 1.60 percent below the Xetra close of Friday, November 6. The Xetra closing level was 255.50 euros, according to StockAnalysis.

Planned succession in benefits

Doyle currently serves as president of the division and will move into the CEO role. Ziebell will leave the CEO position on December 31, 2026, then serve as chairman and continue to provide experience and advice to the business.

The succession is internal and points to continuity rather than a strategic break. For investors, execution under Doyle will matter as Gallagher seeks to extend growth and integrate its businesses across insurance brokerage, risk management and consulting.

Growth outlook stays intact

Gallagher retained its outlook for approximately 6 percent organic growth in 2026 across the combined Brokerage and Risk Management segments. It also expects the full-year adjusted EBITDAC margin to remain above 22 percent and continues to target 160 million US dollars in annualized run-rate synergies by the end of 2026.

In the third quarter ended September 30, combined Brokerage and Risk Management revenue grew 18 percent, including 5 percent organic growth. Reported net earnings rose to 406 million US dollars from 273 million US dollars a year earlier, while adjusted diluted earnings per share increased to 3.00 US dollars from 2.31 US dollars.
