This page answers a common executive-compensation question: What Is the Thermo Fisher Scientific CEO-to-Worker Pay Ratio?. The answer draws on SEC DEF 14A proxy statements, the public disclosure mechanism for U.S. public-company executive pay. Every public company must file an annual proxy statement disclosing CEO and named-executive-officer compensation in detail. Why this matters for shareholders: executive compensation is the single most-disclosed governance metric at U.S. public companies, and the Dodd-Frank-mandated say-on-pay vote gives shareholders an explicit channel to express approval or dissent. Reading pay data well — including pay-versus-performance, peer-group selection, and time-vesting structures — is a basic part of stock-by-stock fundamental analysis.
The detailed answer below uses the actual proxy-statement filings, explains how to read them, and translates the executive-compensation accounting into the shareholder-relevant interpretation.

Public companies have been required to disclose the ratio of CEO pay to median-employee pay in their proxy statements since 2018, under Section 953(b) of the Dodd-Frank Act. At Thermo Fisher Scientific, Marc Casper's $12,000,000 total compensation works out to 126 times the $95,000 earned by the company's median employee — a Life Sciences workforce of roughly 122,000 people.
For context, the typical S&P 500 CEO-to-worker pay ratio runs near 300:1, so Thermo Fisher Scientific's 126:1 figure is lower than the large-cap norm. The ratio is driven mostly by equity: Marc Casper received $6,000,000 in stock awards and $1,440,000 in option awards in 2025, versus $1,200,000 in base salary. Median worker pay reflects total cash and benefits for the employee at the 50th percentile of the company's global workforce.
Whether a high ratio is "fair" is contested. Critics argue wide gaps signal misaligned incentives and weak labor bargaining power; defenders argue CEO pay is mostly performance-linked equity that only pays out if shareholders gain. Thermo Fisher Scientific's three-year total shareholder return of 14.5% and Pay-for-Performance grade of B (74/100) are the data points to weigh that against.
In the most recent say-on-pay vote, 90.2% of shareholders approved the executive compensation plan. Strong shareholder support signals broad approval of the pay package.
