    Listen to the news

    Comet Holding (SWX:COTN) set the tone for investor discussion on 20 October 2026 by issuing fresh guidance for fiscal 2026, targeting net sales between CHF 570 million and CHF 590 million.

    The fresh guidance arrives after a strong run in Comet Holding’s shares. The year to date share price return of 51.36% and the 1 year total shareholder return of 88.87% point to investors steadily repricing growth potential and income over the past few years.
