Tencent will no longer work with the blacklisted companies, and some of the individuals who were fired have been reported to public security authorities, according to the company.
The gaming and social media company said the cases involved bribery and embezzlement.
Tencent has been reporting the results of its internal investigations since 2019. But the latest report comes after a year of tighter regulations in China's tech sector and as Beijing scrutinizes the practices of the country's internet titans.
