LANNETT COMPANY REPORTS FISCAL 2006 FOURTH QUARTER AND FULL-YEAR FINANCIAL RESULTS

Philadelphia, PA — September 13, 2006 — Lannett Company, Inc. (AMEX: LCI) today reported its financial results for the full fiscal year and the fourth quarter ended June 30, 2006.

For fiscal year 2006, net sales were $64.1 million, an increase of $19.2 million compared with net sales of $44.9 million in fiscal 2005. Net income was $5.0 million, or $0.21 per basic and diluted share, which included equity-based compensation expense of $1.1 million, net of tax benefit, or $0.05 per basic and diluted share. This compares with a net loss in fiscal 2005 of $32.8 million, or $1.36 loss per basic and diluted share, which included a $46.1 million non-cash impairment loss on intangible assets and no equity-based compensation expense. Equity-based compensation expense was adopted at the beginning of fiscal year 2006 in accordance with the Statement of Financial Accounting Standards No. 123R.

For the fourth quarter of fiscal 2006, net sales were $19.5 million, an increase of $10.1 million compared with $9.4 million in fiscal 2005 fourth quarter. Net income was $0.8 million, or $0.04 per basic and diluted share, which included equity-based compensation expense of $0.3 million, net of tax benefit, or $0.01 per basic and diluted share. This compares with a net loss of $5.7 million, or $0.24 loss per basic and diluted share, for the same period in fiscal 2005.

“In fiscal 2006, we launched a number of new products, established strategic alliances and invested in research and development,” said Arthur Bedrosian, Lannett’s president and chief executive officer. “These efforts combined to fuel the significant top line and bottom line improvement we made this past year over the prior year and position Lannett for continued growth. Looking ahead, we currently anticipate fiscal 2007 net sales to grow in the mid-teen percent range over fiscal 2006.”

For fiscal year 2006, gross profit was $30.2 million, or 47% of net sales, compared with $13.5 million, or 30% of net sales, for fiscal 2005. Research and development expenses were $8.1 million, compared with $6.3 million for the fiscal 2005 full year. Selling, general and administration (SG&A) expenses were $11.8 million, including $1.4 million of equity-based compensation expense, compared with $9.2 million for fiscal 2005. Amortization expense was $1.8 million, compared with $5.5 million for the prior year.

For the fourth quarter of fiscal 2006, gross profit was $9.9 million, or 51% of net sales, compared with negative $3.1 million in the fourth quarter of fiscal 2005. The negative gross profit in the prior year was the result of increased reserves for short dated inventory, primarily Levothyroxine Sodium, and decreased prices for a majority of the product line.

For the fourth quarter of fiscal 2006, research and development expenses increased to $3.3 million from $2.7 million in the same period in 2005. SG&A expenses were $4.5 million, including $0.4 million of equity-based compensation expense, compared with $2.4 million in the fourth quarter of fiscal 2005. Amortization expense was $0.4 million for both periods.
