Press Release Details

INCLINE VILLAGE, Nev., April 27, 2011 /PRNewswire via COMTEX/ --

PDL BioPharma, Inc. (PDL) (Nasdaq: PDLI) today reported financial results for the first quarter ended March 31, 2011.

Total revenues for the first quarter of 2011 were $83.3 million, compared to $62.1 million for the same period of 2010, and include a one-time settlement payment of $10 million from UCB Pharma resolving all legal disputes between the two companies. Excluding the one-time settlement payment, total revenue increased 18 percent for the first quarter of 2011 when compared to total revenue for the same period of 2010.

Royalty revenues for the first quarter of 2011 are based on fourth quarter 2010 product sales by PDL's licensees. Revenue growth for the first quarter of 2011 over the same period in 2010 was primarily driven by increased fourth quarter 2010 sales by the Company's licensees of Herceptin^®, which is marketed by Genentech and Roche; Lucentis^®, which is marketed by Genentech and Novartis; and Tysabri^®, which is marketed by Elan and Biogen Idec. Also contributing to the increased royalty revenue are increased royalties from sales of Avastin^® that was both manufactured and sold outside of the United States. PDL received royalties for these product sales in the first quarter of 2011.

Total general and administrative expenses for the first quarter of 2011 were $5.8 million, compared with $9.4 million for the same period of 2010. The decrease in general and administrative expenses was primarily driven by decreases in legal and professional services expenses. The decrease in legal expense is a result of the conclusion of the outstanding legal issues with MedImmune, the opposition to PDL's European patent in the European Patent Office (EPO) and the interference proceedings in the U.S. Patent and Trademark Office (PTO), all of which were resolved in the first quarter of 2011. The decrease in professional services expense resulted from reduced costs associated with one-time special project costs. Significant components of general and administrative expenses in the first quarter of 2011 were legal fees of $3.5 million, compensation and benefits expense of $0.9 million, and professional services expense of $0.6 million.

Net income for the first quarter of 2011 was $44.5 million, or $0.25 per diluted share, compared with net income of $26.0 million, or $0.15 per diluted share for the same period of 2010.

Net cash used in operating activities for the first quarter of 2011 was $13.2 million, compared with $26.9 million in net cash provided by operating activities for the first quarter of 2010. At March 31, 2011, PDL had cash, cash equivalents and investments of $193.5 million, compared with $248.2 million at December 31, 2010.

RECENT DEVELOPMENTS

Declaration of 2011 Regular Quarterly Dividends and March 15, 2011, Dividend Payment

On February25, 2011, PDL's board of directors adopted a regular, quarterly dividend policy and declared that the quarterly dividends to be paid to PDL stockholders in 2011 will be $0.15 per share of common stock. The dividends are payable on March15, June15,September15 and December15 of 2011 to stockholders of record on March8, June8,September8 and December8 of 2011, the Record Dates for each of the dividend payments, respectively. On March 15, 2011, PDL paid the first quarterly dividend to its stockholders totaling $21.0 million using earnings generated in the first quarter of 2011 and cash on hand.

Resolution of Legal Disputes

In early 2011, we resolved a number of challenges to our Queen et al. patent estate in the United States and in Europe:

• We reached a settlement agreement with MedImmune resolving all disputes between us related to both sales of their product, Synagis^®, and the Queen et al. patent estate, including their challenge to our European patent before the EPO; we agreed to pay MedImmune $92.5 million as a result of this agreement of which we paid $65.0 million in February 2011 and the balance of $27.5 million is due in February 2012;
• We reached a settlement agreement with UCB Pharma resolving all disputes between us, including their challenges to our U.S. patents before the PTO and our European patent before the EPO; we received a $10 million payment in conjunction with this agreement;
• We reached a settlement agreement with Novartis resolving all disputes between us, including their challenge to our European patent before the EPO; the settlement agreement also included the dismissal of Novartis from all claims in the Nevada state court; and
• We acquired BioTransplant Incorporated, a bankrupt company, and instructed its representative to cease its activities before the EPO in the opposition against us.

As a result of the settlements and the acquisition, the EPO cancelled its opposition hearing regarding the appeal of the validity of our European patent and the claims of our European patent are deemed to be valid in this final action of the EPO. In the three months ended March 31, 2011, approximately 40 percent of our revenues were derived from sales of products made in Europe and sold outside of the United States.

Convertible Notes

Effective March 7, 2011, in connection with the dividend payment on March 15, 2011, the conversion ratios for PDL's 2.00% Convertible Senior Notes due February 15, 2012 (the 2012 Notes) and the 2.875% Convertible Senior Notes due February 15, 2015 (the 2015 Notes) were adjusted to 144.474 shares of common stock per $1,000 principal amount or $6.92 per share. The conversion rate for each of the 2012 Notes and the 2015 Notes was previously 140.571 shares of common stock per $1,000 principal amount. In connection with a cash dividend, the conversion rate is increased by multiplying the previous conversion rate by a fraction, the numerator of which is the average closing price of PDL's common stock for the five consecutive trading days immediately preceding the ex-dividend date of March 4, 2011, for the cash dividend, and the denominator of which is the difference of such average closing price less the dividend amount.

Revenue Guidance for 2011

As previously announced, PDL will continue to provide revenue guidance for each quarter in the third month of that quarter. Second quarter 2011 revenue guidance will be provided in early June.
