Since Nintendo and DeNA announced at a joint press conference that they would be forming a business and capital alliance, both companies’ stock has jumped in value, as you can see from the tracking charts (Nintendo above, and DeNA below).
Nintendo will be leveraging DeNA’s expertise in mobile gaming and online infrastructure in order to enter the mobile market, while DeNA benefits from Nintendo’s intellectual properties, which IPs it will be using for new mobile games. The two will also be creating a new Nintendo membership service that will replace Club Nintendo, which is closing on June 30.
