Fiscal 2005 Earnings Guidance

Mylan's fiscal 2005 earnings guidance reflects a continuation of the success achieved to date in fiscal 2004. Financial performance in the pharmaceutical industry is difficult to predict given its regulatory environment, competition within the industry at market formation and throughout a product's life cycle, the increasingly litigious nature of the research and development and product approval process, and other risks associated with Mylan's business. Therefore, when developing Mylan's fiscal 2005 financial guidance, management probability weighs factors which it believes could influence results of operations. For risk factors associated with the Company's business, including future financial performance, please read carefully the Company's most recently filed quarterly report on Form 10-Q and other periodic SEC filings.

Based upon this approach and analysis, the Company projects its fiscal 2005 earnings per diluted share to be $1.30 to $1.40, with the following expectations of its key business drivers:

----------------------------------------------------------------------
Net Revenues                                 Growth of 15% - 20%

Generic Segment

Net revenues for the quarter increased 9% or $23.6 million to $277.4 million from $253.9 million for the same prior year period. This increase is the result of $29.5 million from products launched subsequent to December 31, 2002, largely due to omeprazole, partially offset in part by changes in the portfolio mix.

Gross profit for the quarter increased 17% or $21.9 million to $153.6 million, and gross margins increased from 52% to 55% of net revenues. Earnings from operations increased 16% or $17.8 million to $130.4 million from the same prior year period. The increase in earnings from operations was driven primarily by higher gross profit which was partially offset by increased research and development expense from the continued expansion of the development platform.

For the nine months ended December 31, 2003, net revenues increased $68.3 million or 9% to $832.2 million from $763.8 million. New products launched subsequent to December 31, 2002, contributed net revenues of $102.5 million, largely due to omeprazole.



Gross profit for the nine months ended December 31, 2003, increased 16% or $65.2 million to $461.2 million from fiscal 2003, and gross margins increased from 52% to 55% of net revenues. Operating income for the nine-month period increased by 16% or $55.4 million to $395.1 million from $339.7 million. The increase in operating income was driven by higher gross profit, partially offset by higher research and development expenses.

Brand Segment

For the third quarter, the Brand Segment reported net revenues of $72.3 million, an increase of 9% or $5.7 million from $66.6 million in the same prior year period. Included in third quarter net revenue is $13.2 million related to the sale of the U.S. and Canadian rights to sertaconazole nitrate 2% cream. Gross profit for the third quarter increased $7.8 million or 20% to $45.6 million, which included this sale.

Earnings from operations were $17.1 million compared to $10.7 million in the same quarter of the prior year. The increase was primarily attributable to higher gross profit, partially offset by increased selling and marketing costs due to pre-marketing activities related to apomorphine.

For the nine months ended December 31, 2003, net revenues increased 38% or $57.4 million to $209.1 million from $151.7 million. This increase was primarily the result of sales of Amnesteem™ which was launched in the third quarter of fiscal 2003, as well as the sertaconazole sale.

Gross profit for the first nine months of fiscal 2004 was $123.1 million, an increase of $35.2 million or 40% from $87.8 million in fiscal 2003. Earnings from operations were $38.5 million compared to $11.5 million. The improvement in earnings from operations was the result of increased gross profit partially offset by higher research and development expenses related to nebivolol, and increased selling and marketing costs related to apomorphine pre-marketing activities.



Corporate/Other

General and administrative expenses for the third quarter of fiscal 2004 were $24.7 million, an increase of $4.0 million from the same prior year period. For the nine months ended December 31, 2003, general and administrative expenses were $71.4 million, an increase of $22.5 million from the same prior year period. The increases for both the three and nine month periods were due primarily to increased legal costs.

Other income for the third quarter and nine-month period was $4.2 million and $14.7 million, respectively. Included in other income for the nine months are interest income and a gain of $5.0 million on the sale of an office building, partially offset by losses realized by Somerset Pharmaceuticals, Inc., a company in which Mylan maintains an equity investment.

Fiscal 2004 Earnings Guidance

Mylan reaffirms its fiscal 2004 earnings guidance of $1.11 to $1.18 per diluted share.
