7月21日，赛默飞世尔盘中下跌4.97%，报516.52美元/股，成交额2.87亿美元。
消息面上，生命科学工具和服务板块当日遭遇集体抛售，行业龙头丹纳赫重挫13.15%领跌，Repligen跌7.5%，沃特世涨4.08%表现分化。赛默飞世尔盘前即已下跌3.46%，开盘后跌幅进一步扩大，显示市场对板块整体情绪偏空。此外，赛默飞世尔将于7月23日盘前发布二季度财报，市场预期营收同比增长约9.55%、调整后每股收益5.71美元，财报窗口临近叠加同行大幅下挫，加剧了投资者的观望与避险情绪。此前公司将微生物业务以约10.75亿美元剥离，预计首个完整财年调整后每股收益摊薄0.15美元，也为短期盈利预期增添了不确定性。
