Major news from struggling coffee seller Starbucks (NASDAQ: SBUX) this afternoon: CEO Jim Donald is being replaced by Chairman and visionary Howard Schultz, who will lead a major restructuring of the company.

The company said it will close underperforming US stores and slow its pace of expansion. Shares of Starbucks are up more than 8% after-hours, as investors apparently believe the company's problems can be fixed by a strong and highly-respected leader. Donald's resignation and Schulz's decision to return signal that the company's management is aware of its problems and determined to right the ship.

In a PR announcing the shake-up, Schultz said that "I am enthusiastic about returning to the role of chief executive officer for the long term and excited to lead Starbucks and its dedicated partners (employees) to even greater heights of achievement on a global basis. We must address the challenges we face and we know what has to be done. Put simply, we are recommitting ourselves to what has made Starbucks and the Starbucks Experience so unique: ethically sourcing and roasting the highest quality coffee in the world; the relentless focus on the customer; the trust we have built with our people, and the entrepreneurial risk-taking, innovation and creativity that are the hallmarks of our success."

Whether these initiatives will be enough to combat the company's problems and a big push by McDonald's (NYSE: MCD) into Starbucks' territory remains to be seen. But for now, investors are lovin' it.
