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.

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:

(1) Represents the non-cash portion of the 1% royalty on net sales of Tyvaso DPI earned during the years ended December 31, 2025 and 2024 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 the year ended December 31, 2025 and 2024 totaled $128.1 million and $102.3 million, respectively, of which $12.8 million and $10.2 million, respectively, is remitted to the royalty purchaser.
