VALEANT PHARMACEUTICALS COMPLETES
REDEMPTION OF 6 1/2 PERCENT CONVERTIBLE SUBORDINATED NOTES
- Company Records Impairment Charge for Anticipated Sale of Manufacturing Sites -
COSTA MESA, Calif., July 22, 2004 – Valeant Pharmaceuticals (NYSE: VRX) today announced the completion on July 21, 2004 of the redemption of its outstanding 6 1/2 percent convertible subordinated notes (notes) due 2008. The aggregate principal amount redeemed was $236.6 million. In connection with this repurchase, Valeant will record a pre-tax loss on early extinguishment of debt of approximately $14.0 million in the third quarter of 2004.
The company redeemed all of the notes at a redemption price of 103.714 percent of the principal amount of the notes, plus interest on the notes for the period from July 15, 2004, to July 20, 2004, which interest amounted to $1.083 for each $1,000 of principal, for a total redemption price of $1,038.22 for each $1,000 principal amount of notes.
Valeant redeemed the notes using a portion of the proceeds it received in private transactions in November and December of 2003, in which it issued and sold $240,000,000 of its 3 percent convertible subordinated notes due 2010, $240,000,000 of its 4 percent convertible subordinated notes due 2013, and $300,000,000 of its senior notes due 2011.
In May 2004, Valeant also repurchased $89.4 million of its 6 1/2 percent convertible subordinated notes in an open market transaction. As a result of this redemption, Valeant recorded a pre-tax loss on extinguishment of debt of $5.9 million in the second quarter of 2004.
Valeant also announced that it recorded a pre-tax impairment charge in the 2004 second quarter of approximately $20 million on the anticipated, near-term sale of certain manufacturing facilities. The facilities to be sold are part of the company’s plan to rationalize its global manufacturing and supply chain network down to five sites, which will result in the disposal of 10 sites. The company has recorded minimal tax benefits on the impairment charge in the 2004 second quarter, reflecting the uncertainty of the realization of these benefits in some of the markets where the facilities are located.
Robert W. O’Leary, Valeant’s chairman and chief executive officer, said, “These actions represent major steps toward the completion of our strategic turnaround efforts. The redemption of the 6 1/2 percent convertible notes completes the planned restructuring of our debt that began last year, providing for a better maturity structure and lower overall interest cost. Our global

manufacturing team is making excellent progress in executing the company’s rationalization efforts, and we now expect the sale of certain manufacturing sites to be completed ahead of schedule.”
