WESTLAKE VILLAGE, Calif., Aug. 11, 2021 (GLOBE NEWSWIRE) -- MannKind Corporation (NASDAQ:MNKD) today reported financial results for the quarter and six months ended June 30, 2021.

"I am really proud of how our team has executed so far in 2021 supporting the growth of Afrezza and preparing for the potential commercial launch of Tyvaso DPI," said Michael Castagna, Chief Executive Officer of MannKind Corporation. "With the issuance of the convertible debt in the first quarter and the pay-down and restructuring of our legacy debt in the second quarter, we have a stronger balance sheet with lower interest expense which sets the company up for commercial growth and pipeline advancement."

Second Quarter 2021 Results

Total revenues were $23.3 million for the second quarter of 2021, an increase of $8.2 million, or 54%, reflecting Afrezza net revenue of $10.0 million and collaboration and services revenue of $13.3 million. Afrezza net revenue increased $3.0 million, or 43%, compared to $7.0 million in the second quarter of 2020 as a result of higher prescription demand, the negative effects of the COVID-19 pandemic in the prior year period, a more favorable mix of Afrezza cartridges, and price (including a lower gross-to-net deduction percentage of gross sales). Collaboration and services revenue for the second quarter of 2021 increased $5.2 million, or 64%, compared to the second quarter of 2020, primarily due to the Company's collaboration with United Therapeutics.

Afrezza gross profit for the second quarter of 2021 was $5.6 million compared to $3.3 million in the same period of 2020, a 68% increase that was driven primarily by higher Afrezza revenue and increased manufacturing activities which resulted in a higher amount of costs capitalized to inventory, partially offset by a $2.0 million fee for an amendment of the Company's insulin supply agreement. Gross margin in the second quarter of 2021 was 56% compared to 47% for the same period in 2020. On a non-GAAP basis, which excludes the $2.0 million insulin supply amendment fee, gross margin was 76% for the second quarter of 2021 compared to 47% for the same period in 2020.

Research and development ("R&D") expenses for the second quarter of 2021 were $2.3 million compared to $1.5 million for the second quarter of 2020. This increase of $0.9 million, or 59%, was attributable to increased development activity related to our product pipeline.

Selling, general and administrative ("SG&A") expenses for the second quarter of 2021 were $20.1 million compared to $13.7 million for the second quarter of 2020, an increase of $6.4 million, or 47%, as we expanded our investment behind Afrezza and lowered expenses in the prior year period when we voluntarily reduced compensation and field force activities in response to the onset of the COVID-19 pandemic. As we continued to re-engage our selling activities behind Afrezza, we increased promotional and marketing expenses by $1.8 million and patient support services by $0.6 million. Personnel expenses increased $4.4 million due to the favorable impact of lower spending during the COVID-19 pandemic as well as increased headcount and stock compensation. The increased spending in SG&A in the second quarter of 2021 was partially offset by a reduction for the promotional cost for Thyquidity that was recognized as cost of revenue — collaboration and services in 2021.

For the second quarter of 2021, the loss on foreign currency translation for insulin purchase commitments denominated in Euros was $0.9 million compared to $1.9 million for the second quarter of 2020. The fluctuation was due to the change in the U.S. dollar to Euro foreign exchange rate.

Interest expense on debt for the second quarter of 2021 was $3.2 million compared to $2.4 million for the second quarter of 2020. This increase of $0.8 million was the result of interest on the $230.0 million 2.5% senior convertible notes, partially offset by a decrease in interest due to the repayment of $35.1 million of outstanding principal under the Mann Group non-convertible promissory note and the repayment of $10.0 million outstanding principal under the MidCap credit facility in the second quarter of 2021. In addition, the Company reduced the interest rates under the MidCap credit facility and the Mann Group convertible note through amendments to the respective agreements in the second quarter of 2021.

Loss on extinguishment of debt, a non-cash expense item, for the three months ended June 30, 2021 was $22.1 million as a result of the amendment to the Mann Group convertible note. The accounting for the $22.1 million loss on extinguishment did not result in a change in the financial position of the Company.

The net loss for the second quarter of 2021 was $35.5 million, or $0.14 per share, compared to a $10.3 million net loss in the second quarter of 2020, or $0.05 per share. The increased net loss of $25.3 million was primarily due to a non-cash loss on extinguishment of the Mann Group convertible note of $22.1 million as well as an increase in SG&A expenses and cost of revenue — collaboration and services, partially offset by an increase in Afrezza net revenue and revenues from collaboration and services. Non-GAAP net loss, adjusted to exclude the $22.1 million non-cash loss on extinguishment of the Mann Group convertible note was $13.4 million, or $0.05 per share, for the three months ended June 30, 2021 compared to $10.3 million, or $0.05 per share, for the prior year period.

Six Months June 30, 2021

Total revenues were $40.7 million for the six months ended June 30, 2021, an increase of $9.4 million, or 30%, reflecting Afrezza net revenue of $18.1 million and collaboration and services revenue of $22.6 million. Afrezza net revenue increased 21% compared to $15.0 million for the six months ended June 30, 2020, primarily as a result of higher prescription demand and the negative effects of the COVID-19 pandemic in the prior year period, a more favorable mix of Afrezza cartridges and price (including a lower gross-to-net deduction percentage of gross sales). Collaboration and services revenue for the six months ended June 30, 2021 increased $6.3 million, or 38%, compared to the six months ended June 30, 2020, primarily due to the Company's collaboration with United Therapeutics.

Afrezza gross profit for the six months ended June 30, 2021 was $9.3 million compared to $7.1 million in the same period of 2020, a 31% increase that was driven primarily by higher Afrezza revenue. Cost of goods sold increased $0.9 million compared to the same period in 2020, primarily due to a $2.0 million fee for an amendment of the Company's insulin supply agreement, partially offset by $0.8 million of costs associated with lower manufacturing cost per unit and the termination of the free goods program in December 2020, in addition to $0.5 million of inventory write-offs in 2020. Gross margin for the six months ended June 30, 2021 was 52% compared to 48% for the same period in 2020. On a non-GAAP basis, which excludes the $2.0 million insulin supply amendment fee, gross margin was 63% for the six months ended June 30, 2021 compared to 48% for the same period in 2020.

R&D expenses for the six months ended June 30, 2021 were $4.8 million compared to $3.2 million for the six months ended June 30, 2020. This increase of $1.6 million, or 48%, was attributable to increased development activity related to our product pipeline.

SG&A expenses for the six months ended June 30, 2021 were $37.5 million compared to $28.0 million for the six months ended June 30, 2020, an increase of $9.4 million, or 34%, as we expanded our investment behind Afrezza and lowered expenses in the prior year period when we voluntarily reduced compensation and field force activities in response to the onset of the COVID-19 pandemic. As we continued to re-engage our selling activities behind Afrezza, we increased promotional and marketing expenses by $2.4 million and patient support services by $0.9 million in the first half of 2021. Personnel expenses increased $6.4 million due to the favorable impact of lower spending during the COVID-19 pandemic as well as increased headcount and stock compensation. The increased spending in SG&A in the first half of 2021 was partially offset by a reduction for the promotional cost for Thyquidity that was recognized as cost of revenue — collaboration and services in 2021.

For the six months ended June 30, 2021, the gain on foreign currency translation for insulin purchase commitments denominated in Euros was $2.9 million compared to a $0.1 million loss for the six months ended June 30, 2020. The fluctuation was due to the change in the U.S. dollar to Euro foreign exchange rate.

Interest expense on debt for the six months ended June 30, 2021 was $9.6 million compared to $4.7 million for the six months ended June 30, 2020. This increase of $4.9 million was the result of a $3.7 million milestone obligation achieved in the first quarter of 2021, interest on the $230.0 million 2.5% senior convertible notes issued in the first quarter of 2021, partially offset by a decrease in interest due to the repayment of $35.1 million of outstanding principal under the Mann Group non-convertible promissory note and the repayment of $10.0 million outstanding principal under the MidCap credit facility in the second quarter of 2021. In addition, the Company reduced the interest rates on the outstanding principal balances under the MidCap credit facility and the Mann Group convertible note through amendments to the respective agreements in the second quarter of 2021.

Non-cash loss on extinguishment of debt for the six months ended June 30, 2021 was $22.1 million as a result of the amendment to the Mann Group convertible note. The accounting for the $22.1 million loss on extinguishment did not result in a change in the financial position of the Company.

The net loss for the six months ended June 30, 2021 was $48.4 million, or $0.20 per share, compared to a $19.6 million net loss in the six months ended June 30, 2020, or $0.09 per share. The increased net loss of $28.9 million was primarily due to the non-cash loss on extinguishment of the Mann Group convertible note of $22.1 million as well as an increase in SG&A expenses, cost of revenue – collaboration and services, and loss on purchase commitments, partially offset by an increase in Afrezza net revenues and revenues from collaboration and services. Non-GAAP net loss, adjusted to exclude the $22.1 million non-cash loss on extinguishment of the Mann Group convertible note was $26.3 million, or $0.11 per share, for the six months ended June 30, 2021 compared to $19.6 million, or $0.09 per share, for the same period in the prior year.

Cash, cash equivalents, and investments at June 30, 2021 were $201.4 million compared to $67.0 million at December 31, 2020. The increase in cash, cash equivalents and investments was primarily due to the issuance of $230.0 million of 2.5 % senior convertible notes in the first quarter of 2021.
