Joy Global Inc. Announces Retirement Of Cfo; Roof To Remain During Transition Of Successor

Milwaukee, WI - May 15, 2006 - Inc. (NASDAQ: JOYG) today announced that Donald C. Roof, chief financial officer since 2001, has chosen to retire early from corporate management in order to fulfill several life long ambitions unrelated to business. He will continue in his current role through the hiring and orientation of a new CFO, remaining with the company to support a seamless transition. While no formal date has been set, Roof is expected to remain at least through the end of the calendar year. The company has begun an external search to identify a successor.

"This has been a difficult decision as I thoroughly enjoy my role and experiences at Joy Global," Roof said. "However, there are a number of personal goals I wish to accomplish, and equally important, my wife and I want to spend more time enjoying our family on the West Coast. This company is well positioned for its next phase of growth and I will leave it in great shape. The finances are sound, the control function is well established and deep with talent, and there is a clearly understood strategy in place driven by the hard work and dedication of all of our employees."

The company has engaged the search firm of Christian & Timbers to lead the recruiting effort. As part of the transition, Mike Olsen, who has led the company's control and compliance efforts for the past four years, will reassume the title of chief accounting officer, a role Roof has held for the past few months.

"I am grateful for Don's professionalism, dedication and valuable contributions to this organization over the years. We wish him the very best in his personal endeavors," said John Hanson, chairman and CEO. "He has been a critical member of our executive management team since joining Joy Global shortly before our emergence from reorganization. He has also been a great business partner for me, playing a strong leadership role in charting and implementing our strategies, creating a high level of transparency with our shareholders, and continually improving the financial performance of the company. Today we are an $8 billion market cap, investment grade company due in large part to these contributions. Throughout his tenure, he has had the full confidence and support of the board of directors. Don will be missed."
