Item 4.01. Changes in Registrant’s Certifying Accountant.

(a) PricewaterhouseCoopers LLP (“PwC”) was the independent registered public accounting firm that audited the consolidated financial statements for Allscripts Healthcare Solutions, Inc. (“Allscripts”) for the seven-month transition period ended December 31, 2010 and for the fiscal years ended May 31, 2010 and 2009. On May 23, 2011, the audit committee of Allscripts dismissed PwC as Allscripts’ independent registered public accounting firm. PwC’s reports on Allscripts’ financial statements for the seven-month transition period ended December 31, 2010 and for the fiscal years ended May 31, 2010 and 2009 did not contain an adverse opinion or disclaimer of opinion, or qualification or modification as to uncertainty, audit scope, or accounting principles. In addition, during Allscripts’ seven-month transition period ended December 31, 2010 and the prior two most recent fiscal years and through the date of this report, there were no disagreements with PwC on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of PwC, would have caused it to make reference thereto in their reports for such transition period and fiscal years. During the transition period, the two most recent fiscal years and through May 23, 2011, there have been no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

Allscripts has provided PwC with a copy of the foregoing disclosures and requested that PwC furnish a letter addressed to the United States Securities and Exchange Commission stating whether it agrees with the above statements made by Allscripts. A copy of such letter, dated May 25, 2011, is filed as Exhibit 16.1 to this Form 8-K, and incorporated herein by reference.

(b) On May 23, 2011, the audit committee of Allscripts engaged Ernst & Young LLP (“E&Y”) to be the independent registered public accounting firm for Allscripts for the year ending December 31, 2011. During the seven-month transition period ended December 31, 2010 and during the fiscal years ended May 31, 2010 and 2009, and during the period through May 23, 2011, Allscripts did not consult with E&Y in regards to Allscripts’ financial statements, which were audited by PwC, with respect to any of (i) the application of accounting principles to a specified transaction, either completed or proposed; (ii) the type of audit opinion that was rendered on the Allscripts’ financial statements or the type of audit opinion that might be rendered on Allscripts’ financial statements; or (iii) any other matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K) or a reportable event of the type described in Item 304(a)(1)(v) of Regulation S-K.

At the Annual Meeting of Stockholders held on May 20, 2011, the stockholders of Allscripts Healthcare Solutions, Inc. (the “Company”) approved the Company’s 2011 Stock Incentive Plan (the “2011 Plan”), which had been previously approved by the Board of Directors, subject to stockholder approval.

The following paragraphs provide a summary of certain terms of the 2011 Plan. The 2011 Plan is set forth in its entirety as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The purposes of the 2011 Plan are: (i) to align the interests of the Company’s stockholders and recipients of awards under the 2011 Plan by increasing the proprietary interest of such recipients in the Company’s growth and success; (ii) to advance the interests of the Company by attracting and retaining officers, other key management employees, directors and independent contractors; and (iii) to motivate such persons to act in the long-term best interests of the Company and its stockholders.

Under the 2011 Plan, the Company may grant: (i) non-qualified stock options; (ii) “incentive stock options” (within the meaning of Section 422 of the Internal Revenue Code); (iii) stock appreciation rights (“SARs”); (iv) restricted stock and restricted stock units (“Stock Awards”); and (v) performance units.

Subject to the terms and conditions of the 2011 Plan, the number of shares authorized for grants under the 2011 Plan is 14,000,000, reduced by the number of shares subject to awards granted under prior equity award plans of Allscripts on or after January 1, 2011. The number of shares available for issuance under the 2011 Plan shall be

reduced by one (1) share for any shares subject to a Stock Award or performance unit and by one-half (0.5) of share for any shares subject to a stock option or SAR.
