2025 Results Set Positive Tone for 2026

Roche Holding AG closed 2025 with robust financials that underpin its market position. Core EPS climbed 11% to 19.46 CHF on a diluted basis at constant rates, reflecting resilient demand for medicines and diagnostics. The company reached 39 million patients treated globally and supplied 31 billion diagnostic tests, highlighting scale in both pharmaceuticals and diagnostics segments.

This performance comes against a backdrop of oncology dominance and diagnostic innovations. Blockbusters like Tecentriq and Perjeta continue driving pharma sales, while diagnostics benefit from post-pandemic testing normalization and new molecular tools. Investors note Roche's ability to sustain growth amid patent cliffs and biosimilar competition.

For the SIX Swiss Exchange in CHF, these figures reinforce Roche's dividend appeal. The holding company structure, with Genentech as its U.S. biotech arm, provides diversified exposure without direct operational risks.
