South Korean online game developer Nexon announced on Tuesday that it plans to invest $1.5 billion in other listed entertainment companies.

The investment is “a good use of Nexon’s cash in a market defined by low interest rates,” Owen Mahoney, the chief executive officer of Nexon, said in a statement. Nexon said it held 518 billion yen ($4.8 billion) in cash as of March 31.

“The global entertainment industry is experiencing a profound secular shift from linear to interactive entertainment. We’re looking for companies that share Nexon’s vision for creating and sustaining strong intellectual properties across multiple markets, in multiple formats for long periods of time,” he added. The Tokyo-listed company said it is not releasing details on which companies it will invest in.

The deal comes amid an uncertain business environment due to the coronavirus crisis, with many companies across industries pulling back on investments. But Nexon has been riding on a wave of increasing demand for online entertainment in a time of social distancing and quarantines. The company also said in its first quarter earnings report that it “has been spared the turbulence [of the Covid-19 crisis] due to minimal physical contact with consumers.”

Its shares have hit record levels, up 60% so far this year. The rise boosted the net worth of its founder, Kim Jung-ju, to $9.3 billion, up from $6.3 billion since the last time Forbes calculated the wealth of South Korea’s richest people. Kim, 52, is currently the third-richest man in South Korea after Samsung’s Lee Kun-hee and Celltrion’s Seo Jung-jin.

Nexon reported better-than-expected first quarter revenue of 82.8 billion yen ($770 million), down 11% from the same period last year. It expects revenues in the range of 59 to 64 billion yen in the second quarter, up 10% to 19% year over year.

Nexon has more than 60 games across over 190 countries. Its most famous games are MapleStory, KartRider and Dungeon Fighter.
