DANBURY, Conn. and WESTLAKE VILLAGE, Calif. February 27, 2024 (Globe Newswire) — MannKind Corporation (Nasdaq: MNKD) today reported financial results for the quarter and full year ended December 31, 2023.

“We doubled our total revenues to nearly $200 million in 2023 and ended the year with a robust fourth quarter total revenue of $58 million,” said Michael Castagna, PharmD, Chief Executive Officer of MannKind Corporation. "With our strong year-end cash position of over $300 million, we are well positioned to capitalize on upcoming data read-outs for Afrezza and move MNKD-101 (clofazimine inhalation suspension) into phase 3 and MNKD-201 (nintedanib DPI) into phase 1 in the first half of 2024."

Fourth Quarter 2023 Results

Revenue Highlights

Afrezza® net revenue for the fourth quarter of 2023 increased $3.5 million, or 29%, compared to the same period in 2022 as a result of higher product demand and higher price (including a decrease in gross-to-net adjustments as a percentage of gross sales). V-Go® net revenue for the fourth quarter of 2023 decreased $0.7 million, or 13%, compared to the same period in 2022 as a result of lower product demand and an increase in rebates (as a percentage of gross sales). Collaborations and services revenue increased $7.7 million, or 81%, compared to the same period in 2022 primarily attributable to an increase in manufacturing Tyvaso DPI for United Therapeutics ("UT"). Royalties related to Tyvaso DPI for the fourth quarter of 2023 increased $12.0 million, or 132%, primarily as a result of increased patient demand.

Commercial product gross margin in the fourth quarter of 2023 was 70% compared to 77% for the same period in 2022. The decrease in gross margin was primarily attributable to an increase in cost of goods sold for Afrezza due to the timing of the capitalization of costs to inventory and lower net revenue for V-Go.

Cost of revenue – collaborations and services was $12.0 million for the fourth quarter of 2023 and remained consistent with the same period in 2022. Higher manufacturing volumes resulted in efficiencies which contributed to a lower effective cost per unit.

Research and development ("R&D") expenses for the fourth quarter of 2023 were $9.2 million compared to $7.2 million for the same period in 2022. The $2.1 million increase was primarily attributed to increased development activities for INHALE-3 which commenced in the second quarter of 2023, INHALE-1 and other research and development activities, partially offset by a decrease in development activities for MNKD-101 due to the completion of a toxicology study in 2022.
 

Selling expenses were $11.0 million in the fourth quarter of 2023 compared to $11.6 million for the same period in 2022. The $0.6 million decrease was primarily due to lower promotional activities.

General and administrative expenses for the fourth quarter of 2023 were $9.5 million compared to $10.5 million for the same period in 2022. The $1.0 million decrease was primarily attributable to a decrease in personnel and consulting costs.

Interest income was $1.7 million for the fourth quarter of 2023 compared to $1.0 million for the same period in 2022. The $0.8 million increase was primarily due to higher yields on our marketable securities and money market funds.

Interest expense on notes was $2.5 million and interest expense on financing liability (related to the sale-leaseback of our Danbury manufacturing facility) was $2.7 million for the fourth quarter of 2023 and remained consistent with the same period in 2022.

Loss on available-for-sale securities for the fourth quarter of 2023 was $1.1 million as a result of the change in fair value of the investment which related to credit risk.

Year Ended December 31, 2023

Revenue Highlights

________________________

* Not meaningful

Afrezza net revenue for the year ended December 31, 2023 increased $11.6 million, or 27%, compared to the same period in 2022 primarily as a result of higher product demand and price (including a decrease in gross-to-net adjustments as a percentage of gross sales). V-Go net revenue for the year ended December 31, 2023 increased $6.2 million, compared to the same period in 2022. The increase reflects a full year of sales in 2023 compared to seven months in 2022 after V-Go was acquired in May of that year. Net revenue from collaborations and services for the year ended December 31, 2023 increased $25.0 million, or 90%, primarily as a result of an increase in manufacturing Tyvaso DPI for UT and the deferral of manufacturing revenue in the prior year period until we began commercial manufacturing in May 2022. Royalties related to Tyvaso DPI, launched in the late second quarter of 2022 by UT, reached $72.0 million for the year ended December 31, 2023, reflecting a full year of sales and increasing patient demand over the period.

Commercial product gross margin was 72% for the year ended December 31, 2023 and remained consistent with the same period in 2022.

Cost of revenue – collaborations and services for the year ended December 31, 2023 was $41.9 million and remained consistent with the same period in 2022 as manufacturing activities shifted from preproduction efforts in the first five months of 2022 to full commercial production of Tyvaso DPI thereafter. Higher manufacturing volumes resulted in efficiencies which contributed to a lower effective cost per unit.

R&D expenses for the year ended December 31, 2023 were $31.3 million compared to $19.7 million for the same period in 2022. The $11.6 million increase was primarily attributed to increases in development activities for MNKD-101, costs for INHALE-3, which commenced in the second quarter of 2023, costs for INHALE-1 and other research and development activities.

Selling expenses for the year ended December 31, 2023 were $51.8 million compared to $53.8 million for the same period in 2022. The $2.0 million decrease was primarily due to the termination of an Afrezza pilot promotional effort with a contract sales force targeting primary care physicians, which ended in the third quarter of 2022, partially offset by increased personnel and promotional activities related to the acquisition of V-Go in the second quarter of 2022.

General and administrative expenses for the year ended December 31, 2023 were $42.5 million compared to $37.7 million for the same period in 2022. The $4.8 million increase was primarily attributable to increased personnel and consulting costs, including stock-based compensation and headcount.

Interest income was $6.2 million for the year ended December 31, 2023 compared to $2.5 million for the same period in 2022. The increase was primarily due to higher yields on our marketable securities and money market funds.

Interest expense on notes and milestone rights was $15.2 million and interest expense on financing liability was $9.8 million for the year ended December 31, 2023 and remained consistent with the same period in 2022.

Loss on available-for-sale securities for the year ended December 31, 2023 was $0.2 million as a result of the change in the fair value of the investment which related to credit risk.

Cash, cash equivalents and investments as of December 31, 2023 were $302.3 million.

Non-GAAP Measures

To supplement our consolidated financial statements presented under U.S. generally accepted accounting principles (GAAP), we are presenting non-GAAP income (loss) from operations, non-GAAP net income (loss) and non-GAAP net income (loss) per share - basic, which are 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 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 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 table reconciles our financial measure for income (loss) from operations, net income (loss) and net income (loss) per share ("EPS") for basic and diluted weighted average shares as reported in our consolidated statement of operations to a non-GAAP presentation as adjusted for select non-cash items: 1% royalty on net revenues for Tyvaso DPI ("Sold portion of royalty revenue") and interest expense on the related liability, stock-based compensation expense, gain on foreign currency transaction and gain on available-for-sale securities for the periods presented (in thousands, except per share amounts):

__________________________

(1) Represents the non-cash portion of the 1% royalty on net sales of Tyvaso DPI earned during 4Q 2023 which is remitted to the royalty purchaser and recognized as royalties from collaborations in our consolidated statements of operations. Our revenues from royalties from collaborations during 4Q 2023 totaled $21.0 million, of which $2.1 million will be remitted to the royalty purchaser.
