Year-End Report 2024 – Continued Strong Growth Path, Ambitious Expansion Program Approved

Rapperswil-Jona, April 23, 2025 – The Weidmann technology group, headquartered in Rapperswil-Jona, continued its strong growth trajectory in the 2024 financial year, reaching sales of CHF 530 million — a 19% increase year-over-year. Employee headcount rose by over 10% to more than 3,300. Anticipating a prolonged growth phase in the energy sector, the group has approved an investment program to expand production capacities.

Electrical Technology – Scaling Up for the Booming Transformer Industry

The Electrical Technology division is the global market leader for insulation materials and systems used in high-voltage transformers, supplying the vast majority of transformer manufacturers worldwide. The rapid electrification of industrial, transport, and building sectors — currently still powered by oil, gas, or coal — is driving massive expansion in power transmission networks. Transformers are a critical component of that grid.

As a result, customers already have full factories and healthy order books stretching years ahead. In 2024, Weidmann’s Electrical Technology division was running at full capacity. Major insulation production sites operated 24/7. Large projects in Europe and China further pushed demand in the components segment.

Given the ongoing bullish outlook, several expansion projects for global production sites have been initiated. The focus is also on strengthening regional production, with major investments going into transformerboard facilities in the US and China. The long-term program involves over CHF 200 million in investment and will create 250 new jobs globally. Even at the headquarters in Rapperswil, staffing increased by about 50 employees in response to temporary project demand spikes.

Fiber Technology – Innovation and Sustainability with Cellulose Fibers

The Fiber Technology division is Weidmann’s innovation hub for sustainable, tech-forward applications made from cellulose fibers. In 2024, new base ingredients derived from microfibrillated cellulose were developed for the cosmetics industry — for example, to create low-chemical hair dyes. Weidmann’s recyclable, natural cellulose materials also gained traction in new markets, enabling circular-economy solutions such as furniture structural parts that can be refurbished instead of trashed.

Medical Technology – Steady Ramp-Up in Switzerland and Mexico

This division produces high-precision plastic components for medical diagnostics and drug delivery — mainly for pre-filled syringes. These are manufactured in large volumes under cleanroom conditions and strict quality controls for leading pharmaceutical and diagnostics firms.

In 2024, serial production grew moderately, supported by successful ramp-ups of new product lines at the Rapperswil and Saltillo (Mexico) plants. However, due to a tough economic climate in pharma, only a few new product series were won. Despite this, headcount in Medical Technology rose by over 15%, across sites in Switzerland (Rapperswil, Bad Ragaz) and Mexico.

Outlook for 2025

Electrical Technology is expected to remain fully booked in 2025. The key focus will be on smooth execution of capacity expansions, which are essential for scaling business volume in phases.

For Medical Technology, steady growth is anticipated. Long-term trends remain positive across all divisions. Short-term risks include geopolitical instability, with the unpredictable policies of the new U.S. administration complicating strategic planning.
