Alexion Provides Update on Form 10-Q Filing

NEW HAVEN, Conn., November 9, 2016- Alexion Pharmaceuticals, Inc. (NASDAQ: ALXN) today announced that it has filed with the U.S. Securities and Exchange Commission (SEC) a Form 12b-25 Notification of Late Filing with regard to its Quarterly Report on Form 10-Q for the quarter ended September 30, 2016.

The Audit and Finance Committee of the Board of Directors is conducting an investigation into allegations that recently have been made by a former employee with respect to the Company’s sales practices of Soliris^® (eculizumab). Specifically, the Audit and Finance Committee is investigating whether Company personnel have engaged in sales practices that were inconsistent with Company policies and procedures and the related disclosure and other considerations raised by such practices. The Audit and Finance Committee has retained outside counsel to assist it in the investigation.

At this point in time, the Audit and Finance Committee’s investigation has not identified instances where Soliris orders were not placed by customers for patients or any facts that require the Company to update its previously reported historical results. The Audit and Finance Committee and its counsel are working diligently to complete the investigation, but at this time it is uncertain when this investigation will be complete and what the results of such investigation will be.

The delayed filing does not affect Alexion’s ability to serve existing or new patients worldwide or to progress the Company’s clinical development programs.
