LANNETT REPORTS FISCAL 2009 THIRD QUARTER FINANCIAL RESULTS

Fiscal 2009 Third Quarter Highlights:

·Net sales up 73% to $28.8 million from $16.6 million for the third quarter of last year

·Gross profit increased to $11.6 million, or 40 percent of net sales, compared with $3.9 million, or 24 percent of net sales, for the third quarter of last year

·Net income was $1.3 million, versus net loss of $1.3 million for the fiscal 2008 third quarter

Philadelphia, PA – May 12, 2009 – Lannett Company, Inc. (NYSE AMEX: LCI) today reported financial results for the third quarter and first nine months of fiscal 2009 ended March 31, 2009.

For the third quarter of fiscal 2009, net sales grew 73 percent to $28.8 million from $16.6 million for the third quarter of fiscal 2008.  Net income was $1.3 million, or $0.05 per diluted share, versus a net loss of $1.3 million, or $0.05 per share, for the prior year third quarter.

“Our third quarter financial performance reflected strong sales of several key products as well as growth of our base business products,” said Arthur Bedrosian, president and chief executive officer of Lannett.  “We expect our future performance to benefit from increased sales of our existing product line as well as our pain management products, due to the current market shortage.  In addition, we anticipate lower SG&A expenses following resolution of a litigation matter in March.”

Gross profit for the fiscal 2009 third quarter increased to $11.6 million from $3.9 million for the same period in the prior year.  Research and development expenses were $2.0 million compared with $1.5 million in the comparable prior year period.  Selling, general and administrative expenses increased to $7.5 million from $4.2 million in the same period last year, largely due to legal expenses associated with current patent challenge litigation and, to a lesser extent, severance costs related to the departure of an executive.

For the first nine months of fiscal 2009, net sales grew 62 percent to $83.6 million from $51.7 million for the first nine months of fiscal 2008.  Gross profit more than doubled to $31.6 million from $13.4 million for the same period in the prior year.  Research and development expenses were $5.7 million compared with $3.7 million in the comparable prior year period.  Selling, general and administrative expenses increased to $19.1 million from $12.5 million in the same period last year, largely due to legal expenses associated with current patent challenge litigation and, to a lesser extent, severance costs related to the departure of an executive.  Net income was $4.1 million, or $0.17 per diluted share, versus a net loss of $2.0 million, or $0.08 per share, for the prior year period.
