The agency sent out a press release that reads as follows.

"As the lawful management of EXO members Kris and Luhan, after filing a lawsuit in February 2015 against Luhan and the companies employing him as an endorsement model for his illegal celebrity activities, SM Entertainment has now officially filed a lawsuit against against Kris, and the advertisement companies and movie production companies who have employed Kris for his illegal activities. The lawsuit has been registered on July 30 at the Beijing court.

After one-sidedly filing a lawsuit against the agency in May 2014, Kris left without notice and has been illegally appearing on various movies, advertisements, event, and awards ceremony using the recognition he has gained through EXO. These activities have infringed the rights of the EXO members and SM, and have caused great financial harm to us and our partners. This is not only an abuse of the system, but also an unethical move that has betrayed the trust of this company and the other members. 

Our contract with Kris remains in effect until the final ruling is made by the court. We will hold him responsible for all the promotions he has illegally conducted during this period. All the activities he has conducted independently including movie and advertisement promotions are also considered a breach of contract. In addition, any individuals or companies that have blindly supported his breach of contract are infringing on the rights and profits of SM and EXO. Thus, we will also hold them responsible and take legal action.

From here on, we will protect our rights and interests of EXO, SM, as well as our partners, and will do all that we can so that no further harm will come to more companies [due to illegally hiring Kris] and so that more will not become involved with Kris's illegal activities."

Meanwhile, SM previously filed their lawsuit against Luhan back in February of this year.
