Philadelphia, PA — September 9, 2009 — Lannett Company, Inc. (NYSE Amex: LCI) today reported financial results for the fiscal 2009 fourth quarter and full year ended June 30, 2009.

For fiscal 2009, net sales rose 64 percent to $119.0 million compared with $72.4 million for fiscal 2008.  Gross profit was $45.2 million compared with $16.3 million for the same period in the prior year.  Research and development (R&D) expenses increased to $8.4 million from $5.2 million in the comparable prior year period.  Selling, general and administrative (SG&A) expenses increased to $26.1 million from $16.6 million in the same period last year.  Net income was $6.5 million, or $0.27 per diluted share, compared with a net loss of $2.3 million, or $0.10 per share, for the prior year.

“Our solid performance in fiscal 2009 was related to strong sales of the company’s key products, as well as increased demand for our existing  products,” said Arthur Bedrosian, president and chief executive officer of Lannett. “Our high-quality manufacturing standards continued to allow us to supply the U.S. market with important medications and alleviate market shortages.”

Bedrosian added that Lannett’s cash position grew to nearly $26 million from $15 million at the end of the previous quarter, further strengthening the company’s balance sheet and providing it with resources for the potential expansion of capabilities and/or acquisition of complementary products and technologies.

For the fourth quarter of fiscal 2009, net sales were $35.4 million compared with $20.7 million for the same period of the prior year.  Gross profit was $13.6 million, compared with $2.9 million for the same period in the prior year.  R&D expenses increased to $2.7 million from $1.5 million in the comparable prior year period.  SG&A expenses increased to $6.9 million compared with $4.1 million in the same period last year.  Net income was $2.4 million, or $0.10 per diluted share, compared with a net loss of

$278,000, or $0.01 per share, which included an income tax benefit of $2.6 million, for the prior year fourth quarter.

The Company recorded income tax expense for 2009 of approximately $4.1 million, but paid only $250,000 due to the reversal of certain deferred tax assets.
