MANNKIND CORPORATION REPORTS THIRD QUARTER FINANCIAL RESULTS

- Conference Call Today at 5:00 p.m. EST -

MannKind Corporation (Nasdaq:MNKD) today reported financial results for the third quarter ended September 30, 2009.

For the third quarter of 2009, total operating expenses were $42.8 million, compared to $69.1 million for the third quarter of 2008. Research and development (R&D) expenses were $30.5 million for the third quarter of 2009 compared to $55.6 million for the same quarter in 2008, a decrease of $25.2 million. This 45% decrease was primarily due to reduced costs associated with the clinical development of AFRESA(R) as the Company completed its pivotal AFRESA trials in 2008, as well as decreases in clinical supplies costs. General and administrative (G&A) expenses decreased by $1.2 million or 9% to $12.3 million for the third quarter of 2009 compared to $13.4 million in the third quarter of 2008.

For the first nine months of 2009, operating expenses totaled $154.0 million, compared to $224.0 million in the first nine months of 2008. R&D expenses for the first nine months were $113.2 million, compared to $181.7 million in 2008, a decrease of $68.4 million. The 38% decrease in R&D expenses for the first nine months was primarily due to decreased costs associated with the clinical development of AFRESA as the Company completed its pivotal AFRESA trials in 2008, as well as decreases in cost of clinical supplies. G&A expenses decreased by $1.6 million or 4% to $40.7 million for the first nine months of 2009 as compared to $42.4 million in the same period in 2008. The decrease in G&A expenses for the first nine months of 2009 was primarily due to the nonrecurrence of costs associated with the purchase of patents during the first quarter of 2008, which was partially offset in 2009 by increased professional fees related to the insulin acquisition transaction with Pfizer Inc. during the second quarter of 2009 and partnership discussions during the third quarter of 2009.

The net loss applicable to common stockholders for the third quarter of 2009 was $45.6 million, or $0.42 per share, based on 108.8 million weighted average shares outstanding. This compares to a net loss applicable to common stockholders of $68.5 million, or $0.67 per share, based on 101.6 million weighted average shares outstanding for the third quarter of 2008.

The net loss applicable to common stockholders for the first nine months of 2009 was $160.6 million, or $1.54 per share based on 104.4 million weighted average shares outstanding, compared with a net loss applicable to common stockholders of $219.7 million, or $2.17 per share based on 101.5 million weighted average shares outstanding, for the first nine months of 2008.

Cash, cash equivalents and marketable securities were $56.6 million at September 30, 2009 and $46.5 million at December 31, 2008. Currently, the Company has $200.0 million of available borrowings under the loan agreement with an entity controlled by the Company's principal stockholder.

"While we continue to be fully engaged in the task of navigating our NDA through the FDA review process, we are continuing to run additional studies of AFRESA. The results to date are preliminary, but we have nonetheless observed some interesting and exciting findings," said Alfred Mann, Chairman and Chief Executive Officer. "The more we study our product in different settings and under different conditions, the more we can appreciate how it has the potential to change the way diabetes is treated. In addition, as we get closer to our January 2010 PFUFA date for the first generation of AFRESA, we are increasing the pace of development of the next generation inhaler in order to provide soon an even better therapeutic option for the millions of patients with diabetes."
