Current Trend
Lonza (LONN.SW) shares are moving higher in the near term after strong first-half 2025 results. The stock is at $573.60, up 7.05% year to date and 3.35% over the last five sessions. Despite a modest 0.93% decline over six months, the shares have recovered following the late-July earnings release.
Investment Thesis
Lonza is a leading contract development and manufacturing organization (CDMO) for the pharmaceutical industry. The company is delivering steady revenue growth and improving operating profitability, as confirmed by H1 2025 results. The investment case rests on rising demand for pharma manufacturing outsourcing and Lonza's strong position in the high-margin biologics segment.
Thesis Status
The thesis is fully supported by current results. The company not only met revenue expectations but also raised its full-year 2025 guidance for the core CDMO business. Revenue growth of 17% to CHF 3.58 billion and higher operating margins point to a strategy that is working.
