LANNETT REPORTS RECORD NET SALES FOR FISCAL 2014 FIRST QUARTER

—Adjusted EPS of $0.22 Exceeds Expectations;

Company Revises Fiscal 2014 Guidance Upward—

Philadelphia, PA — November 7, 2013 — Lannett Company, Inc. (NYSE MKT: LCI) today reported financial results for its fiscal 2014 first quarter ended September 30, 2013.

For the fiscal 2014 first quarter, net sales rose 30% to $45.8 million from $35.3 million for last year’s first quarter.  Cost of sales for the fiscal 2014 first quarter included a non-recurring, pre-tax charge of $20.1 million related to the previously announced contract extension with Jerome Stevens Pharmaceuticals, Inc. (JSP) to continue as the exclusive distributor in the United States of three JSP products.  Accordingly, gross profit was $1.3 million, or 3% of net sales.  Excluding the JSP contract renewal charge, gross profit was $21.4 million, or 47% of net sales, compared with $13.6 million, or 39% of net sales, for the fiscal 2013 first quarter.  Research and development (R&D) expenses increased to $4.7 million, compared with $3.8 million for the fiscal 2013 first quarter.  Selling, general and administrative (SG&A) expenses increased to $7.2 million, compared with $6.2 million in the same quarter of the prior year.  Operating loss for the fiscal 2014 first quarter was $10.6 million.  Excluding the JSP contract renewal charge, operating income more than doubled to $9.5 million from $3.7 million in the first quarter of fiscal 2013.

For the fiscal 2014 first quarter, net loss attributable to Lannett Company was $6.0 million, or $0.20 per share.  Adjusted net income, which excludes the impact of the non-recurring JSP contract renewal charge equal to $12.7 million after-tax, was $6.7 million, or $0.22 per diluted share, compared to fiscal 2013 first quarter net income attributable to Lannett Company of $2.9 million, or $0.10 per diluted share.  The fiscal 2013 first quarter included a favorable pre-tax litigation settlement of $1.3 million, equal to $0.02 per diluted share.

“We continued our positive momentum in the fiscal 2014 first quarter with record net sales,” said Arthur Bedrosian, president and chief executive officer of Lannett.  “In addition, excluding the impact of the non-recurring JSP contract renewal charge, our gross profit and bottom-line were the highest in the company’s history.  Our excellent financial performance was driven by strong sales of existing products, price increases and favorable product mix.”

Bedrosian added, “The recently completed contract extension with Jerome Stevens will allow us to continue to market several important medications that have been key drivers of our positive financial performance.  Moreover, last month we successfully closed on a stock offering in which we received net proceeds of approximately $71.5 million.  We intend to use the net proceeds from this offering for potential acquisitions, strategic partnerships and general corporate purposes.”

Guidance for Fiscal 2014

Based on Lannett’s current outlook, the company revised upward its financial guidance for the fiscal 2014 full year as follows:

·                  Net sales in the range of $245 million to $255 million, up approximately 35% from previous guidance of $181 million to $186 million;

·                  Weighted average common shares outstanding for fiscal 2014 to be approximately 35.4 million, the increase reflecting the impact of the recently completed public offering of 4.3 million shares; and,

·                  Capital expenditures in fiscal 2014 are expected to be in the range of $28 million to $32 million, unchanged from previous guidance, which includes the purchase and partial fit-out of a new facility.
