Are They Connected?
No filing, board seat, deal or press release connects the two men. Their names meet in search results because both made 2026 headlines: Lone Star agreed to buy a Lonza business, and Broussard became HP’s interim CEO. Those events are separate. Treat claims of a partnership or friendship between them as unsupported until a reliable source says otherwise.
John Grayken: Age and Background
John Patrick Grayken was born in June 1956 in Cohasset, Massachusetts, which makes him 70. He studied economics at the University of Pennsylvania and earned an MBA at Harvard Business School. Often described as an American-born Irish billionaire, he has lived mainly in the United Kingdom since the late 1990s. He rarely gives interviews.
Grayken’s Career
Grayken ran Brazos Partners, a venture with the Robert M. Bass Group and the FDIC that resolved about 1,300 bad-bank assets from the savings and loan crisis. He raised the Brazos Fund in 1995 and built Lone Star from it. The firm now reports more than $95 billion in commitments across 25 funds.
Lone Star Today
Donald Quintin became Lone Star’s CEO and global president in 2024, while Grayken remains chairman. In March 2026 the firm agreed to buy Lonza’s capsules and health ingredients unit in a deal valued at about $3 billion, with Lonza keeping 40 percent. Completion was expected in the second half of 2026.
Grayken’s Net Worth
No audited figure exists. Forbes ranked Grayken 386th in the world with $6.5 billion in 2021, and a recent aggregator estimates $7.48 billion. Treat the range of roughly $6.5 to $7.5 billion as an informed estimate rather than a fact, since private fund fees and holdings are not publicly disclosed.
Lifestyle and Homes
According to the Boston Globe, Grayken owns a 17,500-square-foot mansion in London’s Chelsea and a 20-acre country manor. He also bought a house on a small island in Cohasset Harbor and reportedly purchased Boston’s Millennium Tower penthouse for around $33 million in 2016. Beyond property, little is known about his daily routine.
Family and Giving
Grayken is married to Eilene Davidson, a Broadway producer whose credits include Prima Facie and A Doll’s House. In 2017 the couple gave $25 million to Boston Medical Center for addiction medicine, and they later announced a $10 million gift to South Shore Health. Reliable details about his siblings and children are not public.
Criticism of Lone Star
Grayken’s record draws sharp criticism. Forbes once called him one of the “robber barons of the new millennium,” and regulators scrutinized the firm’s mortgage servicing and foreclosure practices after the financial crisis. He has denied wrongdoing in disputes elsewhere. A fair profile includes both the success and the controversy.
Bruce Broussard: Age and Background
Bruce Dale Broussard was born around 1961 or 1962 in Hamilton, New York. An HP filing listed his age as 63 in February 2026, so he is 63 or 64 today. He studied at Texas A&M University and earned an MBA in finance from the University of Houston.
Broussard’s Career
Broussard ran Harbor Dental in the late 1990s, then spent 11 years at US Oncology as CFO, CEO and chairman. He joined Humana as president in 2011 and served as CEO from 2013 to 2024. Humana’s revenue grew from $39.1 billion in 2012 to $92.9 billion in 2022 during his tenure.
Interim CEO at HP
HP named Broussard interim CEO on February 3, 2026, after Enrique Lores left to lead PayPal. He had served on HP’s board since 2021. The board formed a search committee for a permanent CEO. No successor announcement turned up in research, so check HP’s investor page for the latest.
Boards and Public Roles
Broussard sits on the boards of HP, Cleveland Clinic, One Call and, since July 2025, Marsh McLennan. He chairs the Trust for the National Mall, a nonprofit partner of the National Park Service, and holds roles with The Business Council and the American Heart Association’s CEO Roundtable.
Broussard’s Net Worth
No dependable total exists. One tracker estimated at least $19 million in April 2025, counting only disclosed stock holdings. That excludes salary, savings and property, so his true wealth is likely higher. Sites claiming $100 million or more rarely cite sources, so treat them cautiously.
Height, Family and Social Media
Neither man has shared a height publicly, so ignore sites that list one. Broussard’s family life is not documented. He posted about the HP role on LinkedIn, but neither man has a verified personal account elsewhere. Be wary of fake profiles using either name, especially ones promoting investments.
Final Thoughts
Grayken and Broussard follow separate paths: one built a global investment firm, the other led major healthcare and technology companies. Net worth figures remain estimates, and personal details are limited. For current information, rely on company announcements and filings rather than aggregator sites.
