Evan G. Greenberg is an American business executive who serves as the Chairman and Chief Executive Officer of Chubb Limited (NYSE: CB), the world's largest publicly traded property and casualty insurance company. Under Greenberg's leadership, Chubb has grown into a global insurance powerhouse with operations spanning multiple continents and business lines, recording record property and casualty underwriting income of $6.53 billion in 2025. Greenberg is the son of Maurice "Hank" Greenberg, the former longtime chief executive of American International Group (AIG), placing him within one of the most prominent families in the history of the global insurance industry. His tenure at Chubb has been defined by disciplined underwriting, strategic acquisitions, and an emphasis on global diversification. Greenberg has emerged as one of the most influential voices in the insurance sector, frequently commenting on issues ranging from property catastrophe reinsurance pricing to litigation finance and emerging risks such as data center insurance.

Early Life

Evan G. Greenberg was born into a family with deep roots in the insurance industry. His father, Maurice R. "Hank" Greenberg, led American International Group (AIG) for nearly four decades, transforming it into one of the world's largest and most influential insurance and financial services organizations. Growing up in this environment, Evan Greenberg was exposed from an early age to the workings of global insurance and risk management. His brother, Jeffrey Greenberg, also pursued a career in the insurance industry, serving as CEO of Marsh & McLennan Companies. The Greenberg family's influence on the American insurance landscape has been described in industry and financial media as spanning multiple generations and companies.

The prospect of a potential combination of Chubb and AIG, as discussed in financial media in late 2025, was described as an "intriguing possibility" that could represent something of a "coup for Greenberg family" given the family's historical ties to both companies. This familial connection between Chubb's leadership and AIG's history has been a recurring theme in coverage of the insurance industry's consolidation trends.

Career

Early Career and Rise at ACE Limited

Before assuming the top role at what is now Chubb Limited, Evan Greenberg built his career in the insurance industry over several decades. He served in various executive capacities at ACE Limited, a Zurich-based insurance holding company that grew through a series of strategic acquisitions into one of the world's largest commercial insurers. Greenberg rose through the ranks at ACE, eventually becoming the company's President and Chief Executive Officer. Under his leadership, ACE pursued an aggressive but disciplined growth strategy, expanding its global footprint and product offerings across property and casualty insurance, accident and health coverage, and reinsurance.

Acquisition of Chubb and Formation of Chubb Limited

The defining transaction of Greenberg's career came with the acquisition of the legacy Chubb Corporation by ACE Limited, a deal that was completed in January 2016. The combined entity adopted the Chubb name, reflecting the acquired company's strong brand recognition, particularly in personal lines and high-net-worth insurance. The merger created the world's largest publicly traded property and casualty insurer, with a broad portfolio spanning commercial and personal insurance lines, as well as reinsurance operations. The company trades on the New York Stock Exchange under the ticker symbol CB.

Following the merger, Greenberg assumed the role of Chairman and Chief Executive Officer of the newly constituted Chubb Limited. He oversaw the integration of the two organizations, combining ACE's global commercial insurance capabilities with Chubb's established position in personal lines and specialty coverage. The integration was viewed within the industry as a significant operational undertaking that ultimately strengthened the combined company's competitive position across multiple markets and geographies.

Leadership Philosophy and Underwriting Discipline

Greenberg has been noted for his emphasis on underwriting discipline, a philosophy that he has articulated in numerous earnings calls and industry presentations. During Chubb's third-quarter 2025 earnings call, Greenberg described the company's competitive mindset, stating, "We act like we're chased every day," reflecting an organizational culture focused on maintaining rigorous standards even during periods of favorable market conditions. This approach has been credited with helping Chubb achieve consistent underwriting profitability across market cycles.

In October 2025, as property insurance and reinsurance markets began to soften, Greenberg publicly stated that Chubb would not chase property catastrophe reinsurance business in a declining rate environment. This stance reflected his broader philosophy of prioritizing adequate pricing and risk selection over premium volume growth. The decision to pull back from softening reinsurance lines exemplified Greenberg's willingness to forgo short-term revenue in favor of long-term profitability, a strategy that has characterized his tenure at the company.

The third-quarter 2025 results showed steady premium growth across key segments, demonstrating that the company's disciplined approach did not come at the expense of business development.

Financial Performance Under Greenberg

Under Greenberg's leadership, Chubb has posted consistently strong financial results. In its full-year 2025 results, the company reported record property and casualty underwriting income of $6.53 billion, representing an 11.6% increase over the prior year's results. This record performance underscored the effectiveness of Greenberg's strategy of combining global diversification with underwriting discipline.

The company's financial strength has also made it a subject of discussion in the context of potential further industry consolidation. In December 2025, Barron's published an analysis exploring the possibility of a Chubb/AIG combination, describing such a deal as one that "could be good for shareholders" of both companies. While no such transaction had been announced as of early 2026, the speculation reflected Chubb's position as one of the insurance industry's most financially robust players and Greenberg's reputation as a strategic dealmaker.

As of February 2026, Greenberg continued to hold a significant personal stake in Chubb Limited. In a transaction dated February 2026, Greenberg sold 15,060 shares of Chubb stock, a transaction that was publicly disclosed in accordance with Securities and Exchange Commission reporting requirements.

Emerging Risks and Data Center Insurance

Greenberg has positioned Chubb as a leader in insuring emerging and complex risks, including those associated with the rapid expansion of data center infrastructure. In early 2026, Greenberg discussed the company's approach to the data center insurance market, noting that Chubb is "one of the few insurers that can offer broad capabilities to cover all" the risks associated with these facilities. However, he also expressed caution, stating that the company was being "careful not to be overly breathless" about the data center opportunity, emphasizing the importance of proper risk assessment and pricing in a rapidly evolving sector.

This measured approach to an emerging market segment reflected Greenberg's broader philosophy of pursuing growth opportunities selectively, ensuring that the company's risk appetite aligns with its ability to underwrite and price coverage accurately.

Advocacy on Litigation Finance

Greenberg has been an outspoken critic of the growth of third-party litigation funding in the United States, which he views as a significant driver of rising claims costs across the insurance industry. In July 2025, Greenberg, along with John Doyle, CEO of Marsh McLennan, publicly criticized what they termed the "litigation investment industry." The two executives issued their remarks in the context of the failure of certain tort reform provisions within broader federal tax reform legislation.

Greenberg has argued that the commercialization of litigation through third-party funding arrangements has contributed to what the insurance industry terms "social inflation"—the tendency for jury verdicts and legal settlements to increase at rates exceeding general economic inflation. His advocacy on this issue has positioned him as one of the insurance industry's most prominent voices on legal reform matters.

ESG and Corporate Governance Controversies

As CEO, Greenberg has also navigated the politically charged environment surrounding corporate environmental, social, and governance (ESG) practices. In October 2025, Chubb came under criticism from certain political commentators and activist groups who characterized the company as among "America's wokest" insurers, taking issue with the company's positions on various ESG-related matters. Chubb became what Insurance Business described as "the latest flashpoint in America's corporate" debate over ESG policies. The controversy reflected broader tensions within the insurance industry and corporate America regarding the role of companies in addressing social and environmental issues.

Family and the Greenberg Insurance Dynasty

The Greenberg family occupies a unique position in the history of the global insurance industry. Evan Greenberg's father, Maurice "Hank" Greenberg, built AIG into one of the world's most important financial institutions over the course of a tenure that lasted from 1967 to 2005. The elder Greenberg's departure from AIG amid an accounting controversy did not diminish the family's continued prominence in the industry.

The potential for a Chubb/AIG combination, as discussed by Barron's in December 2025, carried additional significance because of the Greenberg family's connections to both companies. Such a deal, if it were to occur, would effectively bring AIG—the company Hank Greenberg built—under the control of a company led by his son. Barron's described this scenario as potentially representing a "coup for Greenberg family."

Evan Greenberg's brother, Jeffrey Greenberg, previously served as CEO of Marsh & McLennan Companies, another major player in the global insurance and risk management industry. The Greenberg brothers' concurrent leadership roles at two of the industry's most significant companies underscored the family's pervasive influence across the insurance sector.

Recognition

Under Greenberg's leadership, Chubb has consistently been recognized as one of the world's leading insurance companies. The company's status as the world's largest publicly traded property and casualty insurer, combined with its record financial performance, has cemented its position at the top of the global insurance industry hierarchy.

Greenberg himself has been recognized as one of the most influential executives in the insurance and broader financial services industries. His public commentary on issues such as litigation finance, catastrophe reinsurance pricing, and emerging technology risks has made him a frequently cited voice in insurance industry media and mainstream financial publications including Barron's.

The company's 2025 record of $6.53 billion in property and casualty underwriting income represented a milestone in the company's history under Greenberg's stewardship, reflecting the cumulative impact of his strategic and operational decisions over his tenure.

Legacy

Evan Greenberg's legacy in the insurance industry is closely tied to the transformation of ACE Limited into Chubb Limited—a process that involved both the landmark 2016 acquisition and the subsequent integration and growth of the combined entity into the world's largest publicly traded property and casualty insurer. His emphasis on underwriting discipline, global diversification, and strategic capital deployment has set a standard that other insurance executives and companies have sought to emulate.

Greenberg's willingness to forgo premium growth in softening markets, as demonstrated by his 2025 decision not to chase property catastrophe reinsurance business, has reinforced an industry narrative that long-term profitability requires the discipline to walk away from inadequately priced risks. His articulation of this philosophy—captured in his statement that "We act like we're chased every day"—has become a widely noted expression of competitive intensity within the insurance sector.

His advocacy regarding litigation finance reform has also contributed to an industry-wide conversation about the systemic drivers of claims inflation and the sustainability of the current legal environment for insurers and their policyholders.

The Greenberg family's broader influence on the insurance industry—spanning Hank Greenberg's legacy at AIG, Jeffrey Greenberg's tenure at Marsh & McLennan, and Evan Greenberg's ongoing leadership of Chubb—represents one of the most significant familial legacies in the history of American finance and insurance. The possibility of a Chubb/AIG combination, while speculative as of early 2026, would further consolidate this legacy if it were to materialize.
