The shareholder value that vanished between the announcement of each CEO's arrival and the announcement of their exit, in inflation-adjusted 2026 dollars. Riding a giant down counts; building one up and losing the peak does not.
Steve Ballmer (Microsoft, 2000-2013, $690B)
Microsoft was worth about $560 billion when his promotion was announced in January 2000 and about $290 billion when his retirement broke in August 2013, even as revenue tripled on his watch. Missing search, mobile, and social cost shareholders nearly $700 billion in today's dollars, the largest sum ever erased under one CEO.
Jeff Immelt (General Electric, 2001-2017, $595B)
Jack Welch handed him the most valuable company on Earth: GE was worth roughly $490 billion when Immelt was named successor in November 2000 and about $250 billion when his exit was announced in June 2017. Top-of-market acquisitions and a bloated GE Capital hollowed out the balance sheet, and the full bill arrived under his successor.
Gerald Levin (AOL Time Warner, 2000-2001, $280B)
The Time Warner boss who agreed to merge with AOL at the top of the dot-com bubble, a deal announced in January 2000 with the combined companies valued near $290 billion. By the time he announced his retirement in December 2001 the merged giant was worth about $155 billion, on its way to the largest annual loss in US corporate history.
Hank McKinnell (Pfizer, 2001-2006, $225B)
Pfizer was a roughly $280 billion colossus when McKinnell took the top job at the start of 2001 and a $190 billion one when the board replaced him in July 2006, even though the all-stock Pharmacia deal had added billions of new shares along the way. His estimated $180 million exit package turned the value destruction into a landmark governance scandal.
John Flannery (General Electric, 2017-2018, $210B)
Nobody destroyed value faster. GE was worth about $250 billion when Flannery was named CEO in June 2017 and under $100 billion when the board removed him on October 1, 2018, as insurance shortfalls and power-division writedowns exposed the true state of the Immelt-era books.
Pat Gelsinger (Intel, 2021-2024, $190B)
Intel was a $236 billion company when his hiring was announced in January 2021 and a $104 billion one when the board forced his retirement in December 2024. The foundry buildout consumed tens of billions while Nvidia, AMD, and TSMC ran off with the AI era.
John Akers (IBM, 1985-1993, $190B)
IBM was the world's most valuable company, worth about $80 billion, when Akers was elevated in early 1985; when his resignation was announced in January 1993 it was a $28 billion company that had just posted the biggest loss in American corporate history. In 2026 dollars the wipeout approaches $190 billion.
Dick Parsons (AOL Time Warner, 2002-2007, $185B)
Brought in to steady AOL Time Warner after Levin, Parsons presided over a slide from about $155 billion in December 2001 to roughly $66 billion when Jeff Bewkes was named his successor in November 2007. He settled the lawsuits and paid down the debt, but dial-up melted away and the stock never recovered.
Graça Foster (Petrobras, 2012-2015, $185B)
Petrobras was a $165 billion national champion when her appointment was announced in January 2012 and a $40 billion crisis when she resigned in February 2015 amid the Lava Jato bribery scandal, collapsing oil prices, and a sinking real. Foster herself was never accused of wrongdoing.
Murilo Ferreira (Vale, 2011-2017, $180B)
Vale was worth about $170 billion when his nomination was announced in April 2011, near the peak of the iron ore supercycle, and about $53 billion when his successor was named in February 2017 after the ore crash, the Samarco dam disaster, and Brazil's recession. The metric does not care that much of it was the cycle.
