FirstQuarter 2026 FinancialResults

Revenues

Total revenues for the first quarter of 2026 increased compared to the same period in the prior year due to higher revenue from royalties and commercial product sales. Commercial product sales increased primarily due to net sales of Furoscix. The acquisition of scPharma closed on October 7, 2025. Collaborations and services revenue decreased due to fewer units sold to United Therapeutics (UT). The increase in royalties was due to UT’s increase in net revenue from sales of Tyvaso DPI.

OperatingExpensesandOtherFinancialHighlights

• Cost of goods sold – commercial, excluding amortization of acquired intangible assets, was $7.5 million for the first quarter of 2026, compared to $3.8 million for the same period in 2025, an increase of 99%.
  • The increase is primarily attributable to the inclusion of Furoscix into our product portfolio following the acquisition of scPharma on October 7, 2025. Gross margin decreased in the current period due to the inclusion of Furoscix (on-body infusor), which has a lower gross margin than Afrezza.

• Research and development expenses were $17.2 million for the first quarter of 2026 compared to $11.0 million for the same period in 2025, an increase of 56%.
  • The increase was primarily attributable to higher personnel costs following the acquisition of scPharma and higher costs from advancing the development of nintedanib DPI (MNKD-201) studies.

• Selling, general and administrative expenses were $54.1 million for the first quarter of 2026 compared to $25.0 million for the same period in 2025, an increase of 116%.        
  • The increase was primarily related to costs associated with the promotion and support of Furoscix, as well as higher Afrezza-related expenses including expanding the field-based teams and preparing for a potential pediatric launch.

Non-GAAPMeasures

To supplement our condensed consolidated financial statements presented under GAAP, we are presenting non-GAAP net (loss) income and non-GAAP net (loss) income 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 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 (loss) income and net (loss) income per share ("EPS") for basic weighted average shares as reported in our condensed consolidated statement of operations to a non-GAAP presentation:
