Kadokawa Corporation, the current owner of FromSoft, will retain the majority of shares, owning 69.66 per cent of the studio. Sony will purchase a 14.09 per cent stake, and Tencent subsidiary Sixjoy Hong Kong will acquire 16.25 per cent.
As reported by VGC, Kadokawa states it "recognises the enhancement of capabilities for the creation, development and deployment of game IP as one of the Group’s highest priorities". To that end, FromSoftware will establish a "third-party allotment", essentially allowing for further funding from Sony and Sixjoy.
This funding will primarily be leveraged to allow FromSoft to publish its own games globally. It already self-publishes in Japan, but has relied on larger publishers for other regions, such as Bandai Namco and Activision. Additionally, the studio will "aim to proactively invest in development of more powerful game IP for itself to strengthen FromSoftware’s development capabilities".
Sony has also acquired a minority of shares in other companies lately, such as Epic Games and Devolver Digital. Most recently, the platform holder has added Savage Game Studios to its first-party group. The company's really been splashing the cash this year.
