On July 14, South Korean equipment maker Philoptics announced it will raise KRW 17.4 billion (approximately USD 12.5 million or CNY 90.5 million) through a third-party share allocation to TKG Taekwang, aimed at accelerating its semiconductor glass substrate business and strengthening strategic cooperation between the two companies.

Under the deal, Philoptics will issue 513,015 common shares at KRW 34,000 per share. The payment is scheduled for July 22, and the newly issued shares will be subject to a one-year lock-up period.

Philoptics stated that the capital injection will be used to fund investments in its glass substrate business for semiconductors—a next-generation packaging technology gaining traction in AI and high-performance computing markets.

After the transaction, TKG Taekwang will hold a 2.19% stake in Philoptics. As of the end of March, CEO Han Kisoo remained the largest shareholder with a 25.56% stake, while SVIC No. 67 New Technology Investment Fund held 7.98% as the second-largest shareholder.

The deal signals growing investor interest in glass substrates, which are increasingly viewed as a key enabler for advanced chip packaging technologies.
