Evan G. Greenberg is an American business executive who serves as 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 conglomerate with operations spanning property and casualty insurance, personal accident and supplemental health insurance, reinsurance, and life insurance across numerous countries. In 2025, the company reported record property and casualty underwriting income of $6.53 billion, an 11.6 percent increase over the prior year, underscoring the scale and profitability of the enterprise Greenberg has built. Greenberg is the son of Maurice R. Greenberg, the former longtime chairman and CEO of American International Group (AIG), and his career in insurance has drawn frequent comparisons to and commentary about his family's deep roots in the industry. Known for a disciplined approach to underwriting and a willingness to forgo market share rather than accept inadequate pricing, Greenberg has shaped Chubb into one of the most consistently profitable insurers in the world.

Early Life

Evan G. Greenberg was born into one of the most prominent families in the American insurance industry. His father, Maurice R. "Hank" Greenberg, served as chairman and chief executive officer of American International Group (AIG) for nearly four decades, transforming it into one of the world's largest insurance and financial services organizations before his departure from the company in 2005. Growing up in a household where insurance and global business were constant topics of discussion, Evan Greenberg was exposed to the industry from an early age.

The Greenberg family's involvement in the insurance sector has spanned multiple generations and companies. Evan Greenberg's brother, Jeffrey Greenberg, also pursued a career in insurance, serving as CEO of Marsh & McLennan Companies. The family's deep connections to the insurance world have been a recurring theme in business media coverage, particularly in discussions about potential industry consolidation. A 2025 Barron's analysis of a potential Chubb-AIG combination described such a deal as a potential "coup for Greenberg family," noting the significance of Evan Greenberg's career trajectory from AIG—where he once worked under his father—to building Chubb into a company that rivals and, in many respects, surpasses the AIG his father once led.

Career

Early Career at AIG

Before assuming leadership of the company that would become Chubb Limited, Evan Greenberg spent a significant portion of his early career at American International Group (AIG), the company his father had built into a global insurance powerhouse. At AIG, Greenberg gained extensive experience in underwriting, international operations, and insurance management across multiple geographies. He rose through the ranks at AIG, holding senior positions that provided him with a broad understanding of global insurance markets. Greenberg eventually departed AIG, a move that preceded his ascent to the top of what would become Chubb Limited.

Leadership of ACE Limited and the Chubb Acquisition

Greenberg became chief executive officer of ACE Limited, a Zurich-headquartered insurance holding company with roots in Bermuda that had grown through a series of acquisitions into a major global insurer. Under Greenberg's leadership, ACE pursued an aggressive but disciplined acquisition strategy, expanding its geographic footprint and product capabilities.

The defining transaction of Greenberg's tenure at ACE was the company's 2016 acquisition of the Chubb Corporation, a storied American insurer with a reputation for high-quality personal and commercial lines underwriting. The combined entity adopted the Chubb name, reflecting the acquired company's strong brand recognition, particularly in the high-net-worth personal insurance market. The merger created the world's largest publicly traded property and casualty insurance company, with operations in 54 countries and territories.

The acquisition was notable not only for its scale but for its strategic logic. By combining ACE's international footprint and commercial lines expertise with the Chubb Corporation's strength in North American personal lines and small commercial insurance, Greenberg created a more diversified and resilient enterprise. The integration of the two companies was widely followed in the insurance industry as a test of Greenberg's ability to deliver on the promise of the combination.

Underwriting Discipline and Financial Performance

A central tenet of Greenberg's leadership philosophy has been an unwavering commitment to underwriting discipline—the principle that insurance should be priced to generate an underwriting profit, rather than written at a loss in pursuit of market share. This approach has been a consistent theme in Greenberg's public statements and earnings calls.

During Chubb's third-quarter 2025 earnings call, Greenberg articulated this philosophy, stating, "We act like we're chased every day," a reference to the company's refusal to become complacent even as it has grown to become the industry's largest player. The call showed steady premium growth across key segments and a continued commitment to disciplined underwriting.

In October 2025, as property insurance and reinsurance markets began to soften following a period of significant rate increases, Greenberg signaled that Chubb would not pursue growth at the expense of profitability in the property catastrophe reinsurance segment. "Chubb won't chase property cat reinsurance," the company's stance was summarized, reflecting Greenberg's willingness to cede volume in segments where pricing no longer meets his standards.

This disciplined approach has yielded strong financial results. In its full-year 2025 results, Chubb reported record property and casualty underwriting income of $6.53 billion, representing an 11.6 percent increase over 2024. The results demonstrated the effectiveness of Greenberg's strategy of prioritizing underwriting profitability across market cycles.

Strategic Positioning and Emerging Risks

Under Greenberg's leadership, Chubb has sought to position itself at the forefront of insuring emerging and complex risks. In early 2026, Greenberg discussed the growing opportunity presented by data center construction and operations, a sector experiencing rapid expansion driven by the proliferation of cloud computing and artificial intelligence infrastructure. Greenberg described Chubb as "one of the few insurers that can offer broad capabilities to cover all the" risks associated with data centers, while noting that he was "careful not to be overly breathless" about the opportunity—a characteristically measured assessment that balanced optimism with caution.

This approach to emerging risks exemplifies Greenberg's broader strategy of leveraging Chubb's scale and technical expertise to insure complex exposures that smaller competitors cannot adequately address, while maintaining pricing discipline and avoiding the hype cycles that can lead to underpricing of novel risks.

Industry Advocacy and Litigation Reform

Greenberg has been an outspoken critic of what he and other insurance industry leaders have described as the growing commercialization of litigation in the United States, a phenomenon sometimes referred to as "litigation funding" or "social inflation." In July 2025, Greenberg joined forces with John Doyle, CEO of Marsh McLennan, to publicly criticize what they called the "litigation investment industry." The two executives issued a "forceful rebuke" of America's increasingly commercialized litigation environment in the wake of the failure of certain tort reform provisions in federal tax legislation.

Greenberg has argued that the growth of third-party litigation funding—in which investors finance lawsuits in exchange for a share of any settlement or verdict—has contributed to escalating claims costs, larger jury verdicts, and ultimately higher insurance premiums for consumers and businesses. His advocacy on this issue has positioned him as one of the most prominent industry voices calling for legislative and regulatory action to address the trend.

Potential Chubb-AIG Combination

In December 2025, Barron's published an analysis exploring the possibility of a combination between Chubb and American International Group (AIG), describing it as "an intriguing possibility that could benefit investors." The article noted the familial dimension of such a transaction, given that Evan Greenberg's father, Maurice Greenberg, had built AIG into a global insurance giant before his departure. A Chubb-AIG deal, the article suggested, "could be good for shareholders and a coup for Greenberg family."

While no formal merger proposal was reported as of early 2026, the speculation reflected both the scale of Greenberg's ambitions for Chubb and the industry's recognition that the company, under his leadership, had the financial capacity and operational expertise to absorb even the largest competitors. The potential combination would have reunited, under Greenberg family leadership, the insurance assets that Maurice Greenberg had assembled at AIG with the global platform that Evan Greenberg had constructed at Chubb.

Corporate Governance and ESG Controversies

In October 2025, Chubb became the subject of public criticism from conservative advocacy groups who labeled it "America's 'wokest' insurer," making the company "the latest flashpoint in America's corporate" debates over environmental, social, and governance (ESG) policies. The criticism focused on Chubb's corporate policies related to environmental and social issues, including the company's approach to insuring fossil fuel projects and its diversity initiatives.

The controversy placed Greenberg and Chubb at the intersection of broader cultural and political debates about the role of corporations in addressing social and environmental concerns. The episode illustrated the challenges facing CEOs of large publicly traded companies in navigating competing demands from shareholders, employees, regulators, and advocacy groups across the political spectrum.

Stock Transactions

In February 2026, Greenberg sold 15,060 shares of Chubb stock (NYSE: CB) in a reported transaction, a routine event for executives of publicly traded companies who receive a significant portion of their compensation in equity. Such transactions are disclosed publicly pursuant to Securities and Exchange Commission regulations and are common among senior executives managing diversified personal investment portfolios.

Personal Life

Evan Greenberg is the son of Maurice R. "Hank" Greenberg, the former chairman and CEO of American International Group, and a member of one of the most prominent families in the global insurance industry. His brother, Jeffrey Greenberg, also pursued a career in the insurance sector, serving as CEO of Marsh & McLennan Companies. The Greenberg family's multi-generational presence in the insurance industry has been a subject of extensive business media coverage, with analysts and journalists frequently noting the parallels and contrasts between the careers of father and son.

Greenberg has maintained a relatively private personal life compared to the level of public attention his professional role commands. His public persona is shaped primarily by his appearances at investor conferences, earnings calls, and industry events, where he is known for detailed and forthright commentary on market conditions, underwriting trends, and regulatory issues.

Recognition

Greenberg's leadership of Chubb has drawn significant attention from the financial and insurance trade press. Under his stewardship, Chubb has been recognized as the world's largest publicly traded property and casualty insurer, a distinction that reflects both organic growth and the transformative 2016 acquisition of the Chubb Corporation.

The company's consistent financial performance under Greenberg has been a frequent subject of analyst coverage and business journalism. Chubb's record 2025 underwriting results—$6.53 billion in property and casualty underwriting income—represented a tangible measure of the operational and strategic achievements of Greenberg's tenure as CEO.

Greenberg's public commentary on industry issues, including litigation finance reform and emerging risk categories such as data center insurance, has positioned him as one of the most quoted and influential voices in the global insurance sector. His measured approach to market opportunities—exemplified by his caution about being "overly breathless" regarding new business lines—has been noted by industry observers as characteristic of his leadership style.

Legacy

Evan Greenberg's legacy is defined primarily by the construction of Chubb Limited into the world's largest publicly traded property and casualty insurer. Through the strategic acquisition of the Chubb Corporation in 2016 and continued organic growth across global markets, Greenberg transformed ACE Limited from a mid-sized specialty insurer into a diversified global insurance powerhouse. The company's consistent emphasis on underwriting discipline—maintaining profitability standards even when doing so means forgoing premium volume—has become a defining characteristic of Chubb under Greenberg's leadership and has influenced broader industry discussions about the balance between growth and profitability.

The familial dimension of Greenberg's career adds a notable layer to his legacy. As the son of Maurice Greenberg, who built AIG into one of the world's largest insurers, Evan Greenberg's success at Chubb has invited comparisons across generations. The December 2025 Barron's analysis of a potential Chubb-AIG combination highlighted the possibility that Greenberg could, through such a transaction, reunite significant portions of the global insurance empire his father had assembled—an outcome that would represent an extraordinary arc in the history of the American insurance industry.

Greenberg's advocacy on issues such as litigation finance reform and his measured approach to emerging risks like data center insurance reflect a leadership style that prioritizes long-term value creation over short-term headline-grabbing. His public statements consistently emphasize the importance of technical underwriting expertise, disciplined capital allocation, and the ability to assess and price complex risks accurately—principles that have driven Chubb's performance during his tenure and that he has sought to embed in the company's culture.

As of early 2026, Greenberg continues to serve as Chairman and CEO of Chubb Limited, overseeing a company with record financial results and a global presence that few competitors can match.
