TMO

Thermo Fisher Scientific (TMO), classified in the Health Care sector, has drawn disclosed trading activity from 23 members of Congress across 67 total transactions spanning from January 2021 through June 2026, with purchases outpacing sales 37 to 30. The most active disclosers by trade count include Ro Khanna, Markwayne Mullin, Dan Newhouse, and Julia Letlow, and the record shows two bipartisan co-trading clusters across that period. In the executive branch, 32 officials have separately disclosed 70 transactions in the same security, with the closest congressional and executive purchases falling zero days apart in the public filing record — a sequence observed in independent disclosures. TMO is among the more widely held Health Care names in the congressional disclosure record, with net buying reflecting the modest but consistent skew toward purchases across the full timeframe.
