Mylan Reports Second Quarter and First Half Fiscal 2006 Financial Results

Mylan Reports Second Quarter and First Half Fiscal 2006 Financial Results- Company on Pace With Fiscal 2006 Adjusted Earnings Guidance -

PITTSBURGH, Oct 27, 2005 /PRNewswire-FirstCall via COMTEX News Network/ -- Mylan Laboratories Inc. (NYSE: MYL) today announced its financial results for the second quarter ended September 30, 2005. The Company reported adjusted earnings per diluted share of $0.22 and GAAP earnings per diluted share of $0.16. For the six months ended September 30, 2005, the Company reported adjusted earnings per diluted share of $0.48 and GAAP earnings per diluted share of $0.31. Mylan today reaffirmed its fiscal 2006 adjusted diluted EPS guidance of $0.92 to $1.15, and its GAAP diluted EPS guidance of $0.73 to $0.96. The Company's fiscal 2007 guidance of $1.20 to $1.74 also remains unchanged.

Robert J. Coury, Mylan's Vice Chairman and Chief Executive Officer, commented: "We are pleased with the announcements we've made today, and are on pace to meet our previously announced earnings guidance. As we've stated before, we view 2006 as a transformational year, with the closing of Mylan Bertek and the planned outlicensing of nebivolol. We are also very excited about our recent lower court victory on oxybutynin, our final approval on amlodipine and our continued position with fentanyl as the only FDA-approved AB rated generic alternative to Duragesic."

In the first quarter of fiscal 2006, Mylan began providing adjusted earnings per diluted share, which is a non-GAAP measure, in order to enhance investors' and other readers' understanding and assessment of the Company's financial performance. Adjusted earnings per diluted share does not include the following items: (1) certain ongoing research and development and marketing costs related to nebivolol (the Company's next-generation beta blocker) that will be incurred until an out-licensing agreement relating to such product is signed, (2) costs, including restructuring costs, related to Mylan Bertek, the subsidiary that Mylan announced in the first quarter that it was closing, and (3) a contingent legal liability related to previously- disclosed litigation in connection with the Company's lorazepam and clorazepate products. The Company continues to believe that it has meritorious defenses with respect to the claims in the litigation and intends to continue to vigorously defend its position, including pursuing a motion for judgment as a matter of law or, in the alternative, a new trial, and if those motions are denied, pursuing an appeal. A reconciliation of adjusted earnings per diluted share to GAAP earnings per diluted share for the three and six months ended September 30, 2005, and adjusted diluted EPS guidance to GAAP diluted EPS guidance appears below.

Net revenues for the second quarter were $298.0 million compared to $307.0 million in the same prior year period. Net earnings for the three- month period ended September 30, 2005, were $35.8 million compared to $48.7 million for the three months ended September 30, 2004. Earnings per diluted share were $0.18 in the comparable prior year period.

For the first six months of fiscal 2006, net revenues were $621.4 million compared to $646.0 million for the first six months of the prior fiscal year. Net earnings for the year to date period were $78.7 million compared to $130.7 million in the same prior year period. In the prior year, earnings per diluted share for the first six months were $0.48, which includes net gains of approximately $0.06 from the settlement of other litigation.

Financial Summary

Net revenues for the second quarter of fiscal 2006 decreased by 3% or $9.0 million to $298.0 million from $307.0 million in the same prior year period. This decrease was the result of overall unfavorable pricing, primarily the result of increased competition, partially offset by revenue from new products. Products launched subsequent to October 1, 2004, contributed net revenues of $34.0 million during the second quarter, substantially all of which is due to the Company's launch of its fentanyl transdermal system in January 2005.

Gross profit for the second quarter of fiscal 2006 decreased by 8% or $12.0 million to $143.2 million from $155.3 million in the same prior year period. Operating income was $58.0 million for the three months ended September 30, 2005, a decrease of $15.5 million from the same prior year period. Lower gross profit and increased research and development ("R&D") expense, primarily due to an increase in ongoing studies including those with respect to nebivolol, were responsible for the decrease in operating income.

The second quarter results include a restructuring charge of approximately $9.4 million related to the closure of Mylan Bertek, of which $8.6 million is recorded in selling, general and administrative ("SG&A") expenses, and the remainder in R&D. Partially offsetting these cost increases were savings realized from the closure of Mylan Bertek, primarily payroll and payroll related costs.

For the six months ended September 30, 2005, net revenues decreased by 4% or $24.6 million to $621.4 million from $646.0 million in the comparable prior year period. This decrease is the result of overall unfavorable pricing, partially offset by favorable product mix and revenue from new products. New products contributed net revenues of $88.1 million in the current fiscal year, substantially all of which is due to fentanyl.

Gross profit for the six months ended September 30, 2005, decreased by 7% or $23.9 million to $311.1 million from $335.0 million in the same prior year period. Despite the difficult pricing environment, gross margins remained relatively stable at 50.1% for the current year to date period compared to 51.9% in the prior year.

Operating income was $117.5 million for the six months ended September 30, 2005, a decrease of $82.5 million from the same prior year period. SG&A expenses increased primarily due to the restructuring, while R&D expense increased as a result of an increase in ongoing studies, including those with respect to nebivolol. In addition to the increased operating expenses, operating income decreased as a result of lower gross profit and the negative impact of litigation in the current year compared to the prior year. In the prior year, $26.0 million of net gains on legal settlements were recorded. The current year includes a charge of approximately $12.0 million to accrue for a contingent legal liability with respect to the lorazepam and clorazepate litigation.

The first six months of fiscal 2006 included restructuring charges of approximately $19.6 million related to the closure of Mylan Bertek, of which $18.6 million is recorded in SG&A. This charge consists primarily of severance and related costs, mostly associated with the Mylan Bertek sales force, as well as lease termination costs and sample inventory write-offs.

During the second quarter, Mylan completed a modified "Dutch Auction" self tender in which it accepted for payment an aggregate of 51,282,051 shares of its common stock for an aggregate purchase price of approximately $1.0 billion. Additionally, as part of a previously announced follow-on repurchase program for up to an additional $250.0 million, the Company repurchased approximately 4.3 million shares of its stock during the quarter for an aggregate purchase price of approximately $78.4 million. These transactions were financed in part with proceeds from the sale of 5-3/4% Senior Notes due 2010 ($150 million aggregate principal amount) and 6-3/8% Senior Notes due 2015 ($350 million aggregate principal amount), as well as a $500 million senior secured credit facility. Included as part of the senior secured credit facility is a revolving line of credit in the amount of $225.0 million, against which no borrowings have been made. During the three and six months ended September 30, 2005, $8.9 million was recognized as interest expense on these outstanding borrowings.

Other income for the second quarter and first six months of fiscal 2006 was $4.3 million and $9.9 million, which consists primarily of interest income.

Non-GAAP Financial Measures

Prior to the first quarter of fiscal 2006, Mylan had not disclosed non- GAAP financial measures when providing financial results. However, due primarily to the recent restructuring and the planned outlicensing of the Company's nebivolol product (both of which were announced by Mylan on June 14, 2005), Mylan now believes that an evaluation of its ongoing operations (and comparisons of its current operations with future operations) would be difficult if the disclosure of its financial results were limited to financial measures prepared only in accordance with accounting principles generally accepted in the United States (GAAP). In addition to disclosing its financial results determined in accordance with GAAP, Mylan is disclosing non-GAAP results that exclude items such as those discussed above in order to enhance investors' and other readers' understanding and assessment of the Company's financial performance, because the Company's ongoing, normal business operations do not include such items. Also, management uses these measures internally for forecasting and budgeting. Whenever Mylan uses such a non-GAAP measure, it will provide a reconciliation of non-GAAP financial measures to the most closely applicable GAAP financial measure. Investors and other readers are encouraged to review the related GAAP financial measures and the reconciliation of non-GAAP measures to their most closely applicable GAAP measure set forth below and should consider non-GAAP measures only as a supplement to, not as a substitute for or as a superior measure to, measures of financial performance prepared in accordance with GAAP.
