Nvidia’s deal to acquire Arm is off, the two companies and Arm’s owner SoftBank announced tonight. SoftBank and Nvidia today agreed to drop their efforts to acquire Arm. With this, there is also a major leadership change at Arm. The company’s current CEO, Simon Segars, is leaving his post, effective today, with Rene Haas, the president of Arm’s IP group (and former Nvidia VP and general manager of its computing products business), taking his role as the company says it is exploring a public offering in lieu of the acquisition. The current plan is for the IPO to happen sometime within the next 12 months.

The Financial Times first reported that the deal had collapsed earlier today.
