(1) Amount represents revenue earned beginning on the scPharma acquisition date of October 7, 2025.

Total revenues for the fourth quarter and full year 2025 rose due to increases in revenue from royalties, collaborations and services, and commercial product sales. The increase in royalties was due to UT’s increase in net revenue from sales of Tyvaso DPI^®. Collaborations and services revenue grew due to increased units sold to UT. Revenue from commercial sales increased primarily due to net sales from Furoscix beginning on the scPharma acquisition date of October 7, 2025 as well as an increase in net sales of Afrezza over the prior periods.

Operating Expenses and Other Financial Highlights

Cost of goods sold – commercial, excluding amortization of acquired intangible assets, was $13.9 million for the fourth quarter of 2025, compared to $4.8 million for the same period in 2024, an increase of 190%. For the full year 2025, Cost of goods sold – commercial, excluding amortization of acquired intangible assets, was $26.8 million, compared to $17.4 million for the same period in 2024, an increase of 54%. These increases are primarily attributable to the inclusion of Furoscix following the acquisition on October 7, 2025, as well as increased sales of Afrezza.
Cost of revenue – collaborations and services was $15.7 million for the fourth quarter of 2025, compared to $14.8 million for the same period in 2024, an increase of 6%. For the full year 2025, cost of revenue – collaborations and services was $61.2 million, compared to $59.2 million for the same period in 2024, an increase of 3%. These increases are primarily the result of a higher number of units of Tyvaso DPI sold through to UT compared to the prior periods.
Research and development ("R&D") expenses were $27.6 million for the fourth quarter of 2025 compared to $11.1 million for the same period in 2024, an increase of 148%. For the full year 2025, R&D expenses were $66.3 million compared to $45.9 million in the same period in 2024, an increase of 45%. These increases were primarily attributable to the ICoN-1 clinical study for MNKD-101, which was discontinued in the fourth quarter of 2025, clinical production scale-up for MNKD-201, personnel costs primarily due to a full-year of costs associated with the third quarter of 2024 Pulmatrix transaction, which bolstered our research capabilities and capacity, and ReadyFlow Autoinjector-related expenses. These increases were partially offset by the completion of INHALE-3, the Phase 1 clinical study for MNKD-201, and toxicology studies in 2024, as well as lower costs for INHALE-1 as the study was closed out in the second quarter of 2025.
Selling, general and administrative ("SG&A") expenses were $58.4 million for the fourth quarter of 2025 compared to $24.0 million for the same period in 2024, an increase of 144%. For the full year 2025, SG&A expenses were $144.1 million compared to $94.3 million in the same period in 2024, an increase of 53%. These increases primarily reflect the inclusion of SG&A costs associated with the promotion and support of Furoscix as well as transaction-related costs incurred as part of the acquisition of scPharma. The remainder of the increase was largely attributable to higher headcount and personnel-related expenses in our commercial group as well as increased promotional costs in preparation to support the potential pediatric launch of Afrezza in 2026.

Non-GAAP Measures

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