On August 14, Sony rose 3.3% overnight, trading at $24.39/share, with turnover of $466,000.

The gain follows the official approval of a joint venture between TSMC and Sony Semiconductor Solutions to develop and manufacture next-generation image sensor semiconductors. Sony plans to invest approximately 465 billion yen in the venture, with TSMC's stake valued at up to 282 billion yen, bringing the total investment to roughly 1 trillion yen ($6.4 billion). Sony will hold approximately 60% ownership, appoint the representative director, and lead core image sensor technology R&D. Mass production at the Kumamoto Prefecture facility is targeted for 2029, with the JV expected to supply high-performance camera sensors to Apple for iPhones.

The partnership also aligns with Sony's broader strategic shift toward an asset-light model for its semiconductor operations, as the company redirects resources toward high-margin content businesses including music, film, and gaming. Sony previously reported fiscal Q1 operating profit growth of 40%, beating analyst expectations, and raised its full-year earnings guidance.
