Alcon Plunges 12.11% on Tariff Impact, Revenue Warning

On August 20, 2025, Alcon's stock experienced a significant drop of 12.11% in pre-market trading.

Alcon has revised its 2025 sales guidance downward, attributing the change to the ongoing impact of U.S. tariffs. The company anticipates a $100 million reduction in revenue due to these tariffs, which is expected to affect its core operating margin, projected to be between 19.5% and 20.5%.

In its second-quarter 2025 earnings report, Alcon disclosed a full-year gross tariff impact of approximately $100 million, which is expected to increase the cost of net sales. The company's net income for the quarter was $176 million, or $0.35 per share, compared to $223 million, or $0.45 per share, in the same period last year. Excluding certain items, Alcon reported adjusted earnings of $380 million, or $0.76 per share. Revenue for the quarter rose 3.8% to $2.577 billion from $2.482 billion last year.
