July 7 (Reuters) - Chipmaker Onsemi ⁠on Tuesday said it will sell two manufacturing ⁠facilities as part of broader push to cut ‌costs and boost profit margins.

Shares of the company were down more than 3% in premarket trading. They have gained nearly 75% this year.

Here are ​some details:

• Onsemi makes power and ⁠sensing chips used in ⁠electric vehicles, factories and AI data centers.

• The move is ⁠part ‌of its "Fab Right" strategy to cut costs, improve efficiency and direct resources toward its most competitive ⁠and scalable operations, the company said.

• Onsemi's facility ​in Tarlac, ‌Philippines will be sold to Taiwanese chip firm Greatek ⁠Electronics, which ​specializes in semiconductor packaging and testing. The deal is expected to close in the next three to six months.

• Its Mountain ⁠Top, Pennsylvania, site will go to ​Swedish semiconductor company Silex Microsystems; the transaction is expected to close in January 2028, giving Onsemi time to move production ⁠to other facilities.

• The company did not disclose the financial terms of the deals.

• Both sites will keep running during their transition periods, and Onsemi has agreed to a ​long-term supply deal with Greatek to ⁠ensure customers are not disrupted.

• Together, the sales are expected ​to save Onsemi around $35 million annually, ‌with initial savings beginning in ​2027 and the full benefit realized in 2028.
