First Quarter 2025 Financial Results

Revenues


	Three Months Ended March 31,
	2025		2024		$ Change			% Change
Revenues	(Dollars in thousands)
Royalties	$	30,005	$	22,651	$	7,354			32	%
Collaborations and services		29,376		24,848	$	4,528			18	%
Afrezza		14,887		14,438	$	449			3	%
V-Go		4,086		4,326	$	(240	)		(6	%)
Total revenues	$	78,354	$	66,263	$	12,091			18	%

Total revenues increased $12.0 million, or 18%, in the first quarter of 2025 compared to the same period in the prior year. Revenue increases were driven by higher royalties primarily due to increased patient demand for Tyvaso DPI® and higher revenue from collaborations and services due to increased product sold to United Therapeutics Corporation. Commercial product revenue remained consistent with the prior year period due to an increase in net revenue for Afrezza, mainly due to higher demand and price, partially offset by a decrease in net revenue for V-Go® due to lower demand.

Operating Expenses and Other Financial Highlights

•

Research and development expenses were $11.0 million for the first quarter of 2025 compared to $10.0 million for the same period in 2024, an increase of 10%. The increase was primarily attributable to increased expenditures for development activities, including a Phase 3 clinical study for MNKD-101, clinical production scale up for MNKD-201, and personnel costs primarily due to additional headcount as a result of MannKind's transaction with Pulmatrix, Inc. in the third quarter of 2024, which bolstered our research capabilities and capacity.

•

Selling, general and administrative expenses were $25.0 million for the first quarter of 2025 compared to $22.3 million for the same period in 2024, an increase of 12%. This increase was primarily attributable to increases in headcount, personnel costs and Afrezza promotional costs, partially offset by a loss of $1.2 million in the prior year period for estimated returns associated with sales of V-Go that pre-dated MannKind's acquisition of the product.

•

For the first quarter of 2025, MannKind reported net income of $13.2 million, or $0.04 earnings per share – basic, compared to net income of $10.6 million, or $0.04 earnings per share – basic, for the same period in 2024, an increase in net income of $2.5 million, or 24%.

•

For the first quarter of 2025, MannKind reported non-GAAP net income of $21.6 million, or $0.07 earnings per share – basic, compared to non-GAAP net income of $15.1 million, or $0.06 earnings per share – basic, for the same period in 2024, an increase in net income of $6.5 million, or 43%. For a reconciliation of GAAP reported net income and net income per share for basic weighted average shares to these non-GAAP measures, please see Non-GAAP Measures below.

Non-GAAP Measures

To supplement MannKind's condensed consolidated financial statements presented under GAAP, we are presenting non-GAAP financial measures for net income and net income per share – basic. We are providing these non-GAAP financial measures, which are among the indicators management uses as a basis for evaluating our financial performance, to disclose additional information to facilitate the comparison of past and present operations. 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 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 Quarterly Report on Form 10-Q 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 and net income per share ("EPS") for basic weighted average shares as reported in our condensed consolidated statements of operations to a non-GAAP presentation:


	Three Months Ended March 31,
	2025						2024
	Net Income			Basic EPS			Net Income			Basic EPS
	(In thousands except per share data)
GAAP reported net income	$	13,158		$	0.04		$	10,630		$	0.04
Non-GAAP adjustments:

Interest expense on liability for sale of future royalties		3,577			0.01			4,248			0.03
Stock compensation		5,385			0.02			3,885			0.01
Loss (gain) on foreign currency transaction		2,509			0.01			(1,399	)		(0.01	)
Non-GAAP adjusted net income	$	21,629		$	0.07		$	15,099		$	0.06
Weighted average shares used to compute net income per share – basic		303,481						270,356
