Taiwan-based GlobalWafers' proposed €4.35B takeover of German chip supplier Siltronic falls apart as Germany's government misses the approval deadline
Germany's economy ministry said it could not complete its review of a planned sale of chip supplier Siltronic to Taiwanese rival GlobalWafers …
Context & Ripple Effects
The collapse ends a deal first struck in December 2020, when GlobalWafers agreed to buy Siltronic for roughly $4.5B in what would have created the world's largest silicon wafer maker by revenue. For over a year the transaction sat pending Germany's economy ministry review, which never reached a decision before the approval deadline lapsed.
The failure lands awkwardly for Berlin: it comes as Germany struggles to hold other chip investments together, from the finance minister ruling out budget money for Intel's €10B subsidy demand for Magdeburg to TSMC's Taiwanese suppliers complaining about EU permitting and labor complexity. Meanwhile GlobalWafers has already rerouted its capital westward.
First-order effects
- Siltronic remains an independent German wafer maker, and GlobalWafers loses the acquisition that would have made it the world's largest silicon wafer producer by revenue.
- GlobalWafers' growth plan shifts fully organic: the company had already finalized $406M in CHIPS Act funding for Texas and Missouri plants, and separately committed to lifting its total US investment to $7.5B.
Second-order effects
- Capital that might have consolidated European wafer capacity now compounds American capacity instead — GlobalWafers' $4B US top-up directly follows the deal's death, deepening the US share of its expansion.
- Germany's chip-supply ambitions take a reputational hit among Taiwanese suppliers weighing EU projects, at exactly the moment TSMC's vendor network is flagging permitting friction around the €10B Dresden plant.
Third-order effects
- If the pattern holds — a missed review deadline here, an unbudgeted Intel subsidy there — Europe risks becoming the slow-approval jurisdiction in a subsidy race the US CHIPS pipeline is winning, leaving wafer and fab investment to concentrate in the US and Asia.
- Wafer-market consolidation proceeds without the German asset, pointing toward a structure where scale players grow through greenfield US plants rather than cross-border M&A subject to European review timelines.
The trend: Semiconductor investment is migrating toward jurisdictions that approve and fund fastest, and Germany's missed deadline hands another round of Taiwanese supplier capital to the US.
