CHICAGO, Dec. 19, 2012 /PRNewswire/ — Allscripts Healthcare Solutions, Inc. (NASDAQ: MDRX) today announced that it has named Paul M.

Lee Shapiro also will step down as President, effective immediately, and will serve as a consultant to Mr. Black for up to six months. In addition, the Company announced that the Board has formally concluded its evaluation of strategic alternatives.

“We want to thank Glen Tullman for building Allscripts into one of the leaders in the evolving healthcare IT industry,” said Dennis Chookaszian, Allscripts Chairman of the Board. “Glen began at the Company in 1997 when it was unprofitable, turned Allscripts around and achieved record revenues and profits in 2011. Along the way, Glen also grew the workforce to more than 7,000 employees. I also want to thank Lee Shapiro for his many important contributions to Allscripts, particularly with respect to our M&A strategy and international expansion.”

Commenting on the selection of Paul M. Black as President and CEO, Mr. Chookaszian said: “Paul possesses a unique blend of operational, healthcare and IT sector expertise, and we are pleased that he has agreed to lead the Company at this critical juncture. Paul’s deep domain expertise in healthcare technology, industry relationships, and understanding of Allscripts’ solutions and client base make him the ideal choice. Together with our recently appointed Chief Financial Officer Rick Poulton, we are confident that we have a leadership team in place that can execute on our strategic initiatives, capitalize on the many global opportunities that lie ahead, and lead Allscripts through its next phase of growth.”

Commenting on the strategic alternatives process, Mr. Chookaszian stated: “The Board conducted a thorough and rigorous review of strategic alternatives. The Board concluded, however, that the best course at this time is to develop Allscripts’ long-term potential under the direction of our new management team.”

Incoming Chief Executive Officer, Mr. Black said, “I look forward to building on the many successes achieved by the Allscripts team. Without underestimating the challenges ahead, we have compelling open-platform solutions, an impressive global client base, and a very dedicated and talented team. We will improve the execution of our strategic vision, deliver on our worldwide client commitments, and continue to innovate. Our focus will be on creating long-term value for our shareholders.”

Glen Tullman added, “It’s always been Allscripts’ goal to revolutionize healthcare and I am proud that Allscripts’ employees have moved this industry forward in both the US and abroad – enabling more people to access our healthcare systems, adding thousands of jobs, and developing an industry that will be one of the biggest

future growth engines of the U.S. economy. Allscripts’ team has shown great resilience and dedication, and I appreciate their hard work to build Allscripts into a leading provider of clinical software, connectivity and information solutions. I am confident that Allscripts is in good hands and has a bright future ahead.”
