Ownership & Acquisition History
Amplitude SAS is not currently controlled by a private equity firm; control sits with Zydus (via its control of Amplitude Surgical SA).
Notes
- Control/ownership change: Zydus announced completion of its block acquisition on July 29, 2025, reaching 85.6% of Amplitude Surgical’s share capital and voting rights (i.e., Zydus control). ([live.euronext.com](https://live.euronext.com/en/products/equities/company-news/2025-07-29-zydus-announces-completion-acquisition-856-stake?utm_source=openai))
- Further confirmation of controlling stake: Zydus MedTech (France) SAS declared crossing up to 90.31% of Amplitude Surgical’s capital and voting rights on July 29, 2025. ([webdisclosure.fr](https://www.webdisclosure.fr/press-release/amplitude-surgical-epa-ampli-franchissement-de-seuils-et-declaration-dintention-WufMWMjmDXZ?utm_source=openai))
- Because Amplitude SAS is the operating subsidiary within the Amplitude Surgical group (manufacturing/distribution entity), control of the group by Zydus implies Amplitude SAS is not PE-controlled today. (Group structure context shown in Amplitude Surgical URD describing Amplitude SAS as a key group company.)
