Shenzhen Transsion Holdings Co, the biggest seller of mobile phones in Africa, is weighing a second listing in the Hong Kong Special Administrative Region, according to people with knowledge of the matter.

Transsion is in talks with advisers about an offering that could raise about $1 billion, though the exact size, as well as timing, has not been determined, the people said, asking not to be identified because the information is private.

Considerations are at an early stage and the company may decide not to pursue a listing in the HKSAR, they added.

Transsion did not respond to requests for comment.

Transsion already trades in Shanghai, where its shares have retreated 22 percent this year, leaving it with a market value of about 85 billion yuan ($12 billion).

Proceeds from listings in the HKSAR have climbed to about $16 billion in 2025, driven in large part by companies that already trade on Chinese mainland exchanges, including battery maker Contemporary Amperex Technology Co Ltd.

Transsion sold 201 million mobile phones worldwide in 2024, taking top spot in Bangladesh, Pakistan, the Philippines, as well as Africa, according to the company’s website. Its mobile brands are Tecno, Infinix and itel.
