PDL BioPharma Announces Delay in Filing Quarterly Report on Form 10-Q

INCLINE VILLAGE, NV, August 8, 2014 – PDL BioPharma, Inc. (PDL) (NASDAQ: PDLI) today announced that the Company has filed a Form 12b-25 Notification of Late Filing with the U.S. Securities and Exchange Commission (SEC) allowing for a five-day extension to file its Quarterly Report on Form 10-Q for the period ended June 30, 2014.

The Company has not yet finalized its financial statements for the quarter ended June 30, 2014, due to additional time necessary to address SEC comments and finalize its review related to a change in the accounting treatment of the acquisition of Depomed royalty rights. As previously disclosed, PDL was asked by the SEC to support its position and explain why this transaction was accounted for as the acquisition of intangible assets as opposed to that of financial assets.

As a result of the delay in filing the quarterly report, PDL has postponed its second quarter earnings release call, originally scheduled for Monday, August 11, until further notice.
