Strong growth and AssuredPartners deal at Gallagher (NYSE: AJG)
Arthur J. Gallagher & Co. is soliciting proxies for its 2026 virtual annual meeting, where stockholders will elect 9 directors, ratify Ernst & Young LLP as auditor, and cast an advisory vote on executive pay.
The company highlights a strong 2025, with combined brokerage and risk management adjusted revenue up 20.7% to $13.7 billion, adjusted EBITDAC up 25.7% to $4.8 billion, and 6% organic revenue growth in each segment. Gallagher completed 33 acquisitions representing $3.6 billion of estimated acquired annualized revenue, including AssuredPartners, described as the largest deal in both company and insurance brokerage industry history.
The proxy details board composition, committee structures, sustainability and AI risk oversight, executive and director compensation (including majority performance-based incentives and robust stock ownership guidelines), related-person employment relationships, and equity compensation plans. The board recommends voting FOR all proposals.
Positive
- None.
Negative

Insights
Proxy centers on strong 2025 results, major M&A and stable, pay-for-performance governance.
Arthur J. Gallagher & Co. uses this proxy to pair routine voting items with a recap of a very strong 2025. Adjusted revenue rose 20.7% to $13.7 billion and adjusted EBITDAC grew 25.7% to $4.8 billion, supported by 6% organic growth in both core segments.
The company closed 33 acquisitions representing $3.6 billion in estimated acquired annualized revenue, including AssuredPartners, described as the largest acquisition in its and the insurance brokerage industry’s history. Governance remains conventional: an independent-heavy 9‑member board, a combined Chair/CEO with a long‑tenured lead independent director, and fully independent key committees overseeing audit, risk (including AI and cybersecurity), compensation and nominations.
Executive pay is strongly performance-based. Annual cash incentives max out only at high adjusted revenue and EBITDAC growth thresholds, and PSUs—75% of CEO long‑term incentives—are tied to three‑year adjusted EBITDAC per-share growth, capped at 200% of target. Director and executive stock ownership guidelines, clawback provisions, and explicit compensation risk reviews are highlighted, while stockholders previously supported say‑on‑pay with 91.2% approval in 2025. From an investor perspective, this filing mainly confirms continuity in strategy, acquisition-driven growth, and governance practices rather than introducing new, thesis-changing developments.

For each committee of the Board, the tables below set forth its primary responsibilities, including certain key matters relating to risk oversight, as well as its membership, independence and number of meetings held in 2025. | ||
![]() | ||||
Audit Committee | ||||
The Audit Committee’s responsibilities include general oversight of the integrity of our financial statements; finance activities; our independent registered public accounting firm’s qualifications and independence; the performance of our internal audit function and independent registered public accounting firm; and, in coordination with the Risk and Compliance Committee, our compliance with legal and regulatory requirements and enterprise risk assessment and management. The Audit Committee manages our relationship with our independent registered public accounting firm, including its appointment, retention, termination and compensation. Internal Audit The Committee oversees an internal audit department, the head of which reports directly to the Committee on matters other than day-to-day operations. The internal audit department is independent from management and the Committee defines its responsibilities. Among other things, the purpose of the department is to bring a systematic and disciplined approach to evaluating and improving the effectiveness of our risk management, control and governance processes. The internal audit department evaluates the effectiveness of our risk management processes, performs consulting and advisory services for us related to risk management, and reports significant risk exposures to the Audit Committee or Risk and Compliance Committee, as appropriate. Independence and Audit Committee Financial Experts Each member of the Audit Committee meets the additional heightened independence and other requirements of the NYSE listing standards and SEC rules. In addition, the Board has determined that each of Messrs. Nicoletti and Rosenthal and Ms. Clarke qualifies as an “audit committee financial expert” under SEC rules. | ||||

Compensation Committee | ||||
The Compensation Committee’s responsibilities include reviewing and approving compensation arrangements for our CEO and other executive officers; reviewing our strategies and policies related to human capital management; and reviewing our overall compensation structure to avoid incentives that promote excessive risk-taking by executive officers and other employees (see “Compensation Risk Oversight” below). The Committee engaged a compensation consultant to assist it in carrying out its duties and responsibilities in 2025. The Committee has the sole authority to retain and terminate such compensation consultant and the sole authority to approve such consultant’s fees and other retention terms. For more information regarding the role of the Committee’s compensation consultant in setting compensation, see page 36. Compensation Risk Oversight The Committee reviews our overall compensation policies and practices to determine whether our program provides incentives for executive officers and other employees to take excessive risks. Based upon an analysis conducted by management and discussions between management and the Committee, the Committee has determined that our compensation policies and practices do not present risks that are likely to have a material adverse effect on us or our business. In reaching this determination, the Committee and management noted the following: (i)no single business unit bears a disproportionate share of our overall risk profile; (ii)no single business unit is significantly more profitable than the other business units; (iii)our compensation practices are substantially consistent across all business units both in the amount and types of compensation awarded; (iv)substantially all of our revenue-producing employees are sales professionals whose compensation is tied to the amount of revenue received by the company; (v)our annual cash incentive program caps payouts at 200% of target awards; and (vi)our performance share units (PSUs) are capped at 200% of target awards and are based on average performance over a three-year measurement period. In addition, a significant portion of our senior executives’ compensation is deferred and invested in our stock through our Deferred Equity Participation Plan and our senior executives own significant amounts of stock. Stock options vest on the third, fourth and fifth anniversaries of the grant date and PSUs vest on the third anniversary of the grant date. Based on the above, the Committee believes that our compensation practices help ensure that no single year’s results and no single corporate action has a disproportionate effect on senior executives’ annual compensation, and encourage steady and consistent long-term performance. Independence Each member of the Compensation Committee meets the additional heightened independence and other requirements of the NYSE listing standards. | ||||
