VALENCIA, Calif.--(BUSINESS WIRE)--August 4, 2011--MannKind Corporation (NASDAQ: MNKD) today reported financial results for the second quarter ended June 30, 2011.

For the second quarter of 2011 total operating expenses were $39.2 million, compared to $37.4 million for the second quarter of 2010, an increase of $1.8 million. Research and development (R&D) expenses were $30.3 million for the second quarter of 2011 compared to $26.2 million for the same quarter in 2010, an increase of $4.1 million. This 16% increase in R&D expense was primarily due to a settlement reached with Organon to resolve a dispute that arose in connection with the termination by the Company of an insulin supply agreement. In connection with the settlement, the Company received the first of two shipments of recombinant human insulin from Organon and paid the first of two $8 million installments in the second quarter of 2011. Additionally, the Company recorded a loss contingency as of June 30, 2011 of $3.9 million in connection with the second installment that was paid in the third quarter of 2011. General and administrative (G&A) expenses decreased by $2.3 million to $8.9 million for the second quarter of 2011 compared to $11.2 million in the second quarter of 2010.

For the first six months of 2011, operating expenses totaled $77.2 million, compared to $78.0 million in the first half of 2010. Total R&D expenses for the six months ended June 30, 2011 were consistent with the same period in the prior year. Excluding expenses incurred related to the contract cancellation fee settlement between the Company and Organon of $7.6 million, R&D expenses would have decreased 14% compared to the same period in the prior year. The decrease was due to the positive impact of the Company’s cost cutting measures on operating expenses. G&A expenses decreased by $0.7 million, or 3%, to $20.7 million for the first half of 2011 as compared to $21.3 million in the same period in 2010.

The net loss applicable to common stockholders for the second quarter of 2011 was $44.5 million, or $0.37 per share based on 121.7 million weighted average shares outstanding, compared with a net loss applicable to common stockholders of $42.3 million, or $0.37 per share based on 113.1 million weighted average shares outstanding for the second quarter of 2010. The number of common shares outstanding at June 30, 2011 was 130,905,582, including the 9,000,000 shares loaned to Bank of America under a share lending agreement in connection with senior convertible notes due in 2015. The 9,000,000 shares which will be returned once the entire principal amount of the notes ceases to be outstanding.

The net loss for the first half of 2011 was $86.0 million, or $0.71 per share based on 121.4 million weighted average shares outstanding, compared with a net loss of $87.0 million, or $0.77 per share based on 113.1 million weighted average shares outstanding, for the first half of 2010.

Cash, cash equivalents and marketable securities were $25.3 million at June 30, 2011 and $70.4 million at December 31, 2010. As of June 30, 2011, the Company had $80.0 million of available borrowings under the loan agreement with an entity controlled by the Company’s principal stockholder.
