WHAT WE ESTIMATE
varies

WHAT CAN’T BE KNOWN
private
Private company stakes, trusts, cash, debts, and undisclosed assets. Anyone publishing these as a single number is guessing.

HOW THIS IS CALCULATED
We take the shares Marc Casper reports owning in their most recent SEC Form 4 and multiply by the latest share price. That gives a stake value you can check against the filing itself. Everything beyond that stake — real estate, private holdings, cash, past compensation — is estimated or simply not public, and we say so rather than roll it into one number.
BIOGRAPHY
Marc Casper studied economics at Wesleyan University and earned an MBA from Harvard, starting his career in consulting and private equity at Bain before moving into the laboratory-instruments business as an operator. He ran several scientific-equipment companies earlier in his career.
He joined Thermo Electron in 2001 and became chief executive of Thermo Fisher Scientific in 2009, building it into the dominant supplier of tools and services to the life-sciences industry through a run of large acquisitions, including Life Technologies and PPD.

Casper is a hired executive. His Thermo Fisher stake came from years of stock compensation, the anchor of the number here.

Ranked by filing-verified stake
The stake value is filing-derived and verifiable; any broader “net worth” is an estimate. Share counts are the latest reported on SEC filings and change as the executive trades; the price is the last close, so the stake value moves with the market. This is not an official or complete accounting of anyone’s wealth. Educational only — not investment advice.
