The transaction that closed on 1 July 2026 was the sale of the company’s non-optical analog and mixed-signal sensor business to Infineon for EUR 570 million in cash. The fab’s post-closing ownership and future plans are not established by the announcements described below.
What did ams OSRAM sell to Infineon?
ams OSRAM reported that it completed the sale of its non-optical analog/mixed-signal sensor business to Infineon on 1 July 2026. The company said it received EUR 570 million in cash. The closing announcement describes a business sale; it does not say that Infineon bought the Premstätten wafer fab. ams OSRAM’s 1 July 2026 closing announcement
ams OSRAM characterized the proceeds as supporting balance-sheet strengthening and accelerated deleveraging, alongside a sharper focus on digital photonics. CEO Aldo Kamper said the transaction was a step toward strengthening the balance sheet while advancing that strategic focus. ams OSRAM’s closing announcement
How the announcements developed
| Date | What ams OSRAM said | What it establishes |
|---|---|---|
| 12 January 2026 | The company said it was in advanced discussions about selling certain business activities and that the Premstätten site would be safeguarded long-term. It also said it could not assure the outcome at that stage. January announcement | Discussions were underway and a long-term site commitment was stated; no completed transaction or fab sale was confirmed. |
| 3 February 2026 | ams OSRAM described a strategic refocus toward digital photonics and named automotive, AR smart glasses, biosensing, home and industrial robotics, and AI data-center optical interconnects as opportunities. February strategic update | These were company-identified growth opportunities, not independently verified forecasts or statements about fab ownership. |
| 1 July 2026 | ams OSRAM said the sale of its non-optical analog/mixed-signal sensor business to Infineon had closed for EUR 570 million in cash. Closing announcement | The named business transaction closed; the announcement does not identify the Premstätten fab as an asset sold. |
What is known about the Premstätten fab?
The January statement that the site would be safeguarded long-term is a company commitment about the site, not confirmation of who owns the fab after the later business sale. The closing announcement does not resolve the fab’s post-closing ownership, investment plans, or capacity outlook.

A product-change notice for certain AS5162 versions identifies wafer fabrication at either ams fab B in Austria or TSMC, with wafer probe testing remaining at ams in Austria. That is evidence about the listed product versions and supply chain only; it does not establish the fab’s current ownership, its capacity, or a general production commitment.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What remains unresolved
The available company announcements and product notice do not establish whether the Premstätten wafer fab changed ownership as part of any transaction, what investment it may receive, or how its capacity may develop. Readers assessing the site should distinguish the completed sale of a sensor business from any separate decision about the facility. A current company statement or relevant filing would be needed to settle those fab-specific questions.
Quick Recap
Best Value
- Genuine Silicon Wafer: crafted from high-purity silicon, this 12 inch silicon wafer features a precision double-side polished surface, delivering exceptional smoothness and mirror-like reflectivity on both sides, fitting well with tech decor needs; Please note: wafer pattern may vary from the product images
