"Our belief in Tencent and its management team is steadfast, but we also need to fund continued growth in our core business lines and emerging sectors," Prosus Chairman Koos Bekker said in a statement after the completion of the deal on Thursday.
In a Hong Kong Stock Exchange filing, Tencent said Prosus sold 191.89 million shares for HK$595.00, reducing its stake to 28.9%.
The price was a 5.5% discount to Tencent's Wednesday close of $HK629.50. Tencent stock, which is up 10% this year, traded 2.5% lower in Hong Kong on Thursday.
A statement from Tencent Chairman Pony Ma said he viewed Prosus, which was spun off from Naspers of South Africa in a 2019 IPO, as a "commited strategic partner over a great many years".
"Tencent respects and understands the (stake sale) decision", he said.
Naspers bought the Tencent stake Prosus now holds in 2001.
Prosus has committed to not reducing its remaining stake further for the coming three years.
The block trade was the largest since 2018, when Naspers sold 2% of the group for $9.8 billion, Refinitiv data shows.
Prosus Chief Executive Bob van Dijk said the company has a "healthy set" of potential acquisition targets.
"Food delivery, you know, is an important focus for us," he told reporters on a call. "Edtech (education software) is an important segment for us and fintech is as well, so we see quite a few opportunities."
Prosus owns interests in online food delivery platforms, classified marketplaces and digital payments businesses.
For the half-year to Sept. 30 it reported a 29% increase in core earnings to $2.2 billion, with proceeds from its Tencent stake offsetting losses from other investments.
The sale of the Tencent stake slightly closed a gap between the valuation of Prosus itself, with a market capitalisation of 153 billion euros, and the value of its remaining Tencent stake, worth about 186 billion euros on Thursday.
"When the discount moves in the right direction we're obviously happy, but we're not happy with where it is," Van Dijk said.
He said growth at the company's other businesses would "alleviate the discount over time".
Citigroup, Morgan Stanley and Goldman Sachs were joint global coordinators for the sale.
