DANBURY, Conn. and WESTLAKE VILLAGE, Calif. November 7, 2024 (Globe Newswire) — MannKind Corporation (Nasdaq: MNKD) today reported financial results for the quarter ended September 30, 2024.

“Our business demonstrated double-digit revenue growth compared to last year, led by Tyvaso DPI revenues,” said Michael Castagna, PharmD, Chief Executive Officer of MannKind Corporation. “The third quarter has also been marked by strong progress in our clinical development programs, with enrollment underway in the Phase 3 trial of MNKD-101 to study its effect in NTM lung disease and successful completion of a Phase 1 trial of MNKD-201 for IPF.

Third Quarter 2024 Results

Revenue Highlights


	Three Months Ended September 30,
	2024		2023		$ Change		% Change
	(Dollars in thousands)
Royalties – collaboration	$	27,083	$	20,218	$	6,865		34	%
Revenue – collaborations and services		23,268		13,108	$	10,160		78	%
Net revenue – Afrezza		15,035		13,476	$	1,559		12	%
Net revenue – V-Go		4,693		4,451	$	242		5	%
Total revenues	$	70,079	$	51,253	$	18,826		37	%

In the third quarter of 2024, compared to the same period in 2023:

•

royalties for Tyvaso DPI® increased $6.9 million, or 34%, due to increased sales by United Therapeutics ("UT");

•

collaborations and services revenue increased $10.2 million, or 78%, primarily attributable to an increase in manufacturing activities for Tyvaso DPI;

•

Afrezza® net revenue increased $1.6 million, or 12%, as a result of higher demand and improved gross-to-net adjustments; and

•

V-Go® net revenue increased $0.2 million, or 5%, as a result of improved gross-to-net adjustments and increased price, partially offset by lower product demand.

Commercial product gross margin in the third quarter of 2024 was 84% compared to 78% for the same period in 2023. The increase in gross margin was primarily attributable to an increase in Afrezza net revenue.

Cost of revenue – collaborations and services for the third quarter of 2024 was $14.8 million compared to $10.3 million for the same period in 2023. The $4.5 million increase was primarily attributable to increased manufacturing volume for Tyvaso DPI.

Research and development ("R&D") expenses for the third quarter of 2024 were $12.9 million compared to $10.0 million for the same period in 2023. The $2.9 million increase was primarily attributed to increased costs for a Phase 3 clinical study of MNKD-101, a Phase 1 clinical study of a dry-powder formulation of MNKD-201, and personnel costs due to increased headcount following a transaction with Pulmatrix, Inc.

Selling expenses were $13.1 million for the third quarter of 2024 compared to $13.4 million for the same period in 2023. The $0.3 million decrease was primarily due to reduced personnel costs related to a sales force restructuring completed during the first quarter of 2024, partially offset by an increase in promotional activities.

General and administrative expenses were $10.8 million for the third quarter of 2024 compared to $10.5 million for the same period in 2023. The $0.3 million increase was primarily attributable to increases in personnel costs partially offset by reduced consulting fees.

Interest income, net, was $3.2 million for the third quarter of 2024 compared to $1.6 million for the same period in 2023. The $1.6 million increase was primarily due to an increase in the underlying investments from the proceeds of the sale of 1% of our Tyvaso DPI royalties in December 2023 and higher yields on our securities portfolio.

Interest expense on liability for sale of future royalties was $4.1 million for the third quarter of 2024 and was attributable to imputed interest and amortization of debt issuance costs on the liability recorded in connection with the sale of 1% of our Tyvaso DPI royalties in December 2023.

Interest expense on financing liability related to the sale-leaseback of our Danbury manufacturing facility was $2.5 million for the third quarter of 2024 and remained consistent with the same period in 2023.

Interest expense was $1.8 million for the third quarter of 2024 compared to $2.8 million for the same period in 2023. The decrease of $1.0 million was primarily due to repayment of the MidCap credit facility and Mann Group convertible note in April 2024.

Gain on bargain purchase of $5.3 million for the third quarter of 2024 was the result of the excess of the fair value of net assets acquired over the fair value of the consideration paid in the Pulmatrix transaction.

R&D expenses for the nine months ended September 30, 2024 were $34.8 million compared to $22.0 million for the same period in 2023.

Selling expenses were $36.2 million in the nine months ended September 30, 2024 compared to $40.8 million for the same period in 2023. The $4.6 million decrease was primarily due to reduced personnel costs related to a sales force restructuring completed during the first quarter of 2024.

General and administrative expenses for the nine months ended September 30, 2024 were $34.2 million compared to $33.0 million for the same period in 2023.

Interest income, net, was $9.8 million for the nine months ended September 30, 2024 compared to $4.4 million for the same period in 2023. The $5.4 million increase was primarily due to an increase in the underlying investments from the proceeds of the sale of 1% of our Tyvaso DPI royalties in December 2023 and higher yields on our securities portfolio.

Interest expense was $10.4 million for the nine months ended September 30, 2024 compared to $12.5 million for the same period in 2023. The decrease of $2.1 million was primarily due to repayment of the MidCap credit facility and Mann Group convertible note in April 2024.

Non-GAAP Measures

To supplement our condensed consolidated financial statements presented under U.S. generally accepted accounting principles ("GAAP"), we are presenting non-GAAP net income (loss) and non-GAAP net income (loss) per share - diluted, 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 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 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 measures for net income (loss) and net income (loss) per share ("EPS") for diluted weighted average shares as reported in our condensed consolidated statements of operations to a non-GAAP presentation.

__________________________

(1) Diluted weighted average shares ("DWAS") differs from basic due to the weighted average number of shares that would be outstanding upon exercise or vesting of outstanding share-based payments to employees and conversion of convertible notes. For the three and nine months ended September 30, 2024 DWAS included and 9,695 and 8,596, respectively, shares of outstanding share-based payments. 44,120 shares issuable upon conversion of our Senior convertible notes were excluded as their effect would be antidilutive. For the three months ended September 30, 2023 DWAS included 7,548 shares of outstanding share-based payments, 44,120 shares issuable upon conversion of our Senior convertible notes, and 3,370 shares issuable upon conversion of our Mann Group convertible note.
