onsemi has entered into an agreement with Greatek Electronics Inc., a Taiwan-based semiconductor company specializing in integrated circuit packaging and testing services. The transaction is expected to close within the next three to six months, subject to customary closing conditions and regulatory approvals.
The Tarlac site will continue operating as part of onsemi’s manufacturing network throughout the transition period. The companies have established a long-term supply agreement to support ongoing production and ensure continuity for customer commitments following the close of the transaction.

onsemi has also entered into an agreement with Silex Microsystems, a Sweden-based semiconductor company. The transaction is expected to close in January 2028, subject to customary closing conditions and regulatory approvals.
The extended transition period is intended to allow onsemi to continue an orderly transfer of the products currently manufactured at the site to other facilities within its network, ensuring continuity for customers and a structured migration of technologies.
These actions are expected to result in cost savings of approximately $35 million per year, with initial savings starting in 2027 and the full savings realized in 2028. This represents an important step in shaping a more focused and efficient manufacturing network. By aligning its footprint to long-term strategic priorities, onsemi is strengthening its ability to deliver sustained value to customers and stakeholders.
