MANNKIND CORPORATION REPORTS
2021 THIRD QUARTER FINANCIAL RESULTS

Conference Call to Begin Today at 5:00 p.m. (ET)

WESTLAKE VILLAGE, Calif., November 9, 2021 (Globe Newswire) -- MannKind Corporation (Nasdaq: MNKD) today reported financial results for the quarter and nine months ended September 30, 2021.

“The MannKind team continues to stay focused and execute our corporate objectives of preparing for the commercial launch of Tyvaso DPI, moving our pipeline forward and growing Afrezza,” said Michael Castagna, PharmD, Chief Executive Officer of MannKind Corporation. “The recently completed animal toxicology studies of inhaled clofazimine support our timeline of moving this unique chemical entity into Phase 1 clinical trials by year-end.”

Third Quarter 2021 Results
Total revenues were $22.2 million for the third quarter of 2021, an increase of $6.9 million or 45% from the same period in 2020, reflecting Afrezza net revenue of $9.8 million and collaboration and services revenue of $12.5 million. Afrezza net revenue increased $2.5 million, or 34%, compared to $7.3 million in the third quarter of 2020 as a result of higher prescription demand and price, including lower gross-to-net deductions. Collaboration and services revenue for the third quarter of 2021 increased $4.4 million, or 54%, compared to the third quarter of 2020 primarily due to additional development work associated with our collaboration with United Therapeutics (“UT”).

Afrezza gross profit for the third quarter of 2021 was $5.9 million compared to $3.7 million in the same period of 2020, a 61% increase that was driven primarily by an increase in Afrezza net revenue. Gross margin in the third quarter of 2021 was 61% compared to 51% for the same period in 2020, reflecting the favorable impact of increased revenue.

Research and development (“R&D”) expenses for the third quarter of 2021 were $3.7 million compared to $1.5 million for the third quarter of 2020. This increase of $2.2 million, or 146%, was attributable to research activities on our product pipeline and to the initiation of the Afrezza pediatrics clinical study (INHALE-1).

Selling, general and administrative (“SG&A”) expenses for the third quarter of 2021 were $17.2 million compared to $13.9 million for the third quarter of 2020, an increase of $3.3 million, or 24%. The increase was primarily attributable to promotional expenses and patient support services of $2.0 million as well as personnel-related expenses of $2.6 million, which was driven by increased stock-based compensation and additional headcount to support Afrezza growth. The spending in SG&A in the third 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 third quarter of 2021, the gain on foreign currency translation for insulin purchase commitments denominated in Euros was $2.1 million compared to a loss of $3.9 million for the third quarter of 2020. The fluctuation was due to the change in the U.S. dollar to Euro foreign currency exchange rate.

Interest expense on debt for the third quarter of 2021 was $2.8 million compared to $2.4 million for the third quarter of 2020. This increase of $0.4 million was the result of 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, we 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.

Gain on extinguishment of debt, a non-cash item, for the three months ended September 30, 2021 was $4.9 million as a result of the Small Business Association’s (the “SBA”) forgiveness of our PPP loan in July 2021.

The net loss for the third quarter of 2021 was $4.4 million, or $0.02 per share, compared to $11.3 million in the third quarter of 2020, or $0.05 per share. The decreased net loss of $6.8 million was primarily due to an increase in Afrezza net revenues and revenues from collaboration and services, as well as a non-cash gain on the extinguishment of the PPP loan, partially offset by an increase in the cost of revenue from collaboration and services and of SG&A expenses. Non-GAAP net loss, adjusted to exclude the PPP loan debt extinguishment was $9.4 million, or $0.04 per share, for the three months ended September 30, 2021 compared to $11.3 million, or $0.05 per share, for the prior year period.

Nine Months September 30, 2021
Total revenues were $62.9 million for the nine months ended September 30, 2021, an increase of $16.2 million or 35% from the same period in 2020, reflecting Afrezza net revenue of $27.8 million and collaboration and services revenue of $35.1 million. Afrezza net revenue increased 25% compared to $22.3 million for the nine months ended September 30, 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 lower gross-to-net deductions. Collaboration and services revenue for the nine months ended September 30, 2021 increased $10.7 million, or 44%, compared to the nine months ended September 30, 2020, primarily due to additional development work associated with our collaboration with UT.

Afrezza gross profit for the nine months ended September 30, 2021 was $15.3 million compared to $10.8 million in the same period of 2020, a 41% increase that was driven primarily by an increase in Afrezza net revenue. Cost of goods sold increased $1.1 million compared to the same period in 2020, primarily due to a $2.0 million fee for an amendment of our insulin supply agreement and a $1.1 million decrease in manufacturing activities which resulted in a lower amount of costs capitalized to inventory, partially offset by $0.9 million of costs associated with lower manufacturing cost per unit and the termination of the free goods program in December 2020. Gross margin for the nine months ended September 30, 2021 was 55% compared to 49% for the same period in 2020. On a non-GAAP basis, which excludes the $2.0 million insulin supply amendment fee, gross margin was 62% for the nine months ended September 30, 2021 compared to 49% for the same period in 2020, reflecting the favorable impact of increased revenue.

R&D expenses for the nine months ended September 30, 2021 were $8.4 million compared to $4.7 million for the nine months ended September 30, 2020. This increase of $3.7 million, or 79%, was attributable to costs incurred for research activities on the product pipeline and to the initiation of the INHALE-1 study as well as personnel costs associated with additional headcount.

SG&A expenses for the nine months ended September 30, 2021 were $54.7 million compared to $41.9 million for the nine months ended September 30, 2020, an increase of $12.8 million, or 30%. The increase was primarily attributable to promotional expenses and patient support services of $5.8 million and personnel-related expenses of $8.5 million, which reflected increased stock-based compensation, additional headcount to support Afrezza growth and our voluntary reduction in compensation expense in response to the COVID-19 pandemic in the prior year. The spend in selling expenses was partially offset by a reduction related to the co-promotional cost for Thyquidity, which was recognized as cost of revenue – collaborations and services.

An impairment of $1.9 million was recognized for the nine months ended September 30, 2020 for a commitment asset related to the future funding commitments of the MidCap credit facility.

For the nine months ended September 30, 2021, the gain on foreign currency translation for insulin purchase commitments denominated in Euros was $5.0 million compared to a $4.0 million loss for the nine months ended September 30, 2020. The fluctuation was due to the change in the U.S. dollar to Euro foreign currency exchange rate.

Interest expense on debt for the nine months ended September 30, 2021 was $12.4 million compared to $7.1 million for the nine months ended September 30, 2020. This increase of $5.3 million was the result of a $3.7 million milestone obligation achieved in the first quarter of 2021 and 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, we 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 net loss on extinguishment of debt of $17.2 million for the nine months ended September 30, 2021 consisted of a $22.1 million loss on extinguishment of debt for the amendment to the Mann Group convertible note, which did not result in a change in our financial position, partially offset by a $4.9 million gain on extinguishment of debt as a result of the SBA’s forgiveness of our PPP loan in July 2021.

The net loss for the nine months ended September 30, 2021 was $52.9 million, or $0.21 per share, compared to a $30.8 million net loss in the nine months ended September 30, 2020, or $0.14 per share. The increased net loss of $22.0 million was primarily due to the non-cash loss on extinguishment of the Mann Group convertible note of $22.1 million net of a non-cash gain on extinguishment of the PPP loan of $4.9 million, as well as an increase in SG&A expenses, cost of revenue – collaboration and services, partially offset by an increase in Afrezza net revenues and revenues from collaboration and services. Non-GAAP net loss as adjusted for the $17.2 million net loss on extinguishment of debt and the $2.0 million Amphastar amendment fee was $33.7 million, or $0.14 per share, for the nine months ended September 30, 2021 compared to $30.8 million, or $0.14 per share, for the same period in the prior year.

Cash, cash equivalents, and investments at September 30, 2021 were $181.1 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.

Non-GAAP Measures
To supplement our unaudited condensed consolidated financial statements presented under U.S. generally accepted accounting principles (GAAP), we are presenting certain non-GAAP financial measures. We are providing these non-GAAP financial measures to disclose additional information to facilitate the comparison of past and present operations, and they are among the indicators management uses as a basis for evaluating our financial performance. We believe that these non-GAAP financial measures, when

considered together with our GAAP financial results, provide management and investors with an additional understanding of our business operating results, including underlying trends.

These non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP measures; should be read in conjunction with our unaudited condensed consolidated financial statements prepared in accordance with GAAP; have no standardized meaning prescribed by GAAP; and are not prepared under any comprehensive set of accounting rules or principles. In addition, from time to time in the future there may be other items that we may exclude for purposes of our non-GAAP financial measures; and we may in the future cease to exclude items that we have historically excluded for purposes of our non-GAAP financial measures. Likewise, we may determine to modify the nature of its adjustments to arrive at our non-GAAP financial measures. Because of the non-standardized definitions of non-GAAP financial measures, the non-GAAP financial measures as used by us in this report have limits in their usefulness to investors and may be calculated differently from, and therefore may not be directly comparable to, similarly titled measures used by other companies.

The following tables reconcile our gross margin financial measure to a non-GAAP presentation as adjusted for the nonrecurring amendment fee related to an amendment to our Insulin Supply Agreement.
