** Shares in Alcon ALCC.S are down around 9% as the Swiss-American eye care group cut its 2025 outlook, impacted by U.S. tariffs
** The company lowered its projected net sales range to $10.3 to $10.4 billion from $10.4 to $10.5 billion forecasted in May
** It posted a 4% rise in Q2 sales to $2.58 billion, missing analysts' average forecast of $2.63 billion, according to LSEG data
** "The slight reduction in the FY25 guidance is minimal and even unchanged at the EPS level, but the second downward revision of the forecast this year continues to undermine the management's credibility, which unfortunately tends to be slightly too optimistic," Zuercher Kantonalbank says
** The stock is on track for the worst day since March 2020
