Breton Technology (HKG:1333) agreed to acquire a 21.96% interest in Xingyuan Zhisheng at nil consideration, according to a Tuesday filing with the Hong Kong bourse.

The battery-electric engineering firm's shares gained nearly 2% in pre-market trade Wednesday.

The firm is acquiring the stake from three sellers and will inject around 11 million yuan into the partnership, corresponding to its capital contribution requirement as a partner.

The funds will be used to invest in companies focusing on green and low-carbon and new energy sectors, Breton said.

A portion of the stake to be transferred represents Shanghai Boxi's unpaid subscribed partnership interest in Xingyuan Zhisheng.

Shanghai Boxi, which is associated with the company's controlling shareholder Chen Fangming, had planned to contribute 25 million yuan for a 49.98% partnership interest, but ultimately injected 18 million yuan, corresponding to a 36.02% partnership interest.

Meanwhile, in a separate announcement, Breton Technology said it was acquiring a 6.83% stake in Xingmiao Photoelectric for about 14 million yuan.

The firm will acquire the stake from Cloud Tribe Yijin, an entity tied to Chen.

Breton Technology simultaneously announced an agreement to acquire a 6.82% interest in Suzhou Junhao Electric Power for 13 million yuan.

The firm will acquire the stake from Shanghai CPI Ronghe New Energy Investment Management Center, it said.
