On July 21, Thermo Fisher Scientific fell 4.97% in regular trading, trading at $517.98/share, with turnover of $294 million. The stock had already declined 3.46% in pre-market trading before losses widened during the regular session.

On the news front, the Life Sciences Tools and Services sector experienced a broad selloff, led by industry peer Danaher which plunged over 12%. Repligen fell approximately 7%, while Waters bucked the trend with a gain of over 4%. The sector-wide weakness significantly weighed on Thermo Fisher. Additionally, with the company scheduled to release its Q2 fiscal report on July 23 before market open, the proximity of the earnings window combined with peers sharp declines intensified investor caution and risk-averse sentiment. Market consensus expects Q2 revenue growth of approximately 9.55% year-over-year and adjusted EPS of $5.71.

Within the Life Sciences Tools and Services sector, Danaher fell 12.86%, Repligen fell 6.91%, Waters rose 4.21%, Tempus AI rose 2.21%, and Bio-Techne was flat.
