JAKARTA - US President Donald Trump blocked the acquisition of assets by HieFo Corp against Emcore, a semiconductor and photonics company. This acquisition is worth 3 million US dollars (Rp50.1 billion).

This blocking was carried out because Trump suspected a serious threat to US national security. The White House also stated that HieFo Corp 'is controlled by citizens of the People's Republic of China'.

In line with the statement, launching from Reuters, Trump believes that this acquisition could endanger protection of US military technology. Therefore, HieFo was ordered to divest all rights to Emcore assets.

Trump gave HieFo 180 days to comply with the executive order. Before this decision was made, the Committee on Foreign Investment in the US (CFIUS) had conducted an in-depth investigation into the deal initiated since 2024.

After being investigated, the Department of the Treasury confirmed the existence of a national security risk arising from the transfer of Emcore assets to HieFo Corp. These assets include advanced chip businesses and indium-phosphide wafer fabrication operations.

It should be noted that Emcore is a specialist company in the field of aerospace and maintenance technology. Meanwhile, HieFo Corp is a company founded by former executives at Emcore, including the former vice president of the company's engineering.

Until now, HieFo has not issued an official statement. However, Emcore stated that they would follow Trump's decision because HieFo Corp could not prove that the CFIUS allegations were wrong.

"HieFo Corporation cannot resolve the national security concerns identified by CFIUS," Emcore said on its official website, quoted on Monday, January 5. "Emcore LLC has fully cooperated with all relevant government agencies and fully complies with all applicable regulations."
