Immediate opportunity to increase capacity for formulation and early asset development in upgraded Boston area R&D spaceNon-cash deal includes royalty-free iSPERSE™ technology license in exchange for access to MannKind’s Cricket® inhaler DANBURY, Conn. and WESTLAKE VILLAGE, Calif., May 29, 2024 (GLOBE NEWSWIRE) -- MannKind Corporation (Nasdaq: MNKD), a company focused on the development and commercialization of innovative inhaled therapeutic products and devices for patients with endocrine and orphan lung diseases, announced today that it has agreed to in-license iSPERSE™ technology from Pulmatrix for certain indications in exchange for an out-license of MannKind’s Cricket® inhaler to Pulmatrix for inhaled delivery of dihydroergotamine (DHE) for migraine treatment. The two companies also agreed that Pulmatrix will transfer its Bedford, Mass. R&D facility to MannKind, along with all leasehold improvements, laboratory equipment and other related personal property used in the laboratory in non-cash transaction. “We are delighted to grow our Boston-area presence as we continue to progress our pipeline efforts, and in particular, our expanding orphan lung programs,” said Michael Castagna, PharmD, Chief Executive Officer of MannKind Corporation. “We have formulated two FDA-approved products utilizing our proven Technosphere® dry powder technology, and this agreement affords us access to another option for future development opportunities.” “Our Technosphere technology, which is a unique carrier-based, dry powder inhalation platform used in tandem with our proprietary inhaler, provides deep and effective penetration of lung tissue that is well suited for many active ingredients,” said Dr. Burkhard Blank, Executive Vice President, Research & Development and Chief Medical Officer of MannKind Corporation. “However, for some drug candidates, such as Clofazimine, that may require a significantly higher drug payload, the iSPERSE formulation technology may be better suited for developing viable powders.” The royalty-free licensing structure will allow MannKind to have exclusive use of the iSPERSE technology for clofazimine, NTM, and insulin, and non-exclusive use for endocrine diseases and interstitial lung diseases (ILD) including idiopathic pulmonary fibrosis (IPF), progressive pulmonary fibrosis (PFF) and other related lung diseases. In exchange, Pulmatrix will receive a royalty-free, exclusive license to MannKind’s single-use Cricket inhalation device for inhaled delivery of DHE in any formulation and non-exclusive use for neurological diseases. MannKind expects to consolidate its Boston presence by transitioning its Marlborough staff into the newly renovated, fully outfitted R&D facility in Bedford. To maintain continuity of iSPERSE platform knowledge, MannKind plans to hire some members of current Pulmatrix R&D staff. The agreement is anticipated to close in July 2024.

Collaborations and services revenue increased $13.5 million, or 118%, compared to the same period in 2023 primarily attributable to an increase in manufacturing Tyvaso DPI for United Therapeutics ("UT"). Afrezza® net revenue for the first quarter of 2024 increased $2.0 million, or 16%, compared to the same period in 2023 as a result of higher price (including a decrease in gross-to-net adjustments). V-Go® net revenue for the first quarter of 2024 decreased $0.8 million, or 16%, compared to the same period in 2023 as a result of lower product demand. Commercial product gross margin in the first quarter of 2024 was 80% compared to 69% 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 first quarter of 2024 was $14.8 million compared to $10.7 million for the same period in 2023. The $4.1 million increase was primarily attributable to increased manufacturing volume and related production activities. Higher manufacturing volumes resulted in efficiencies which contributed to a lower effective cost per unit. Research and development ("R&D") expenses for the first quarter of 2024 were $10.0 million compared to $5.6 million for the same period in 2023. The $4.4 million increase was primarily attributed to increased development activities for clofazimine inhaled suspension (MNKD-101), costs for an Afrezza post-marketing clinical study (INHALE-3) which commenced in the second quarter of 2023 and personnel expenses due to increased headcount. Selling expenses were $11.6 million in the first quarter of 2024 compared to $13.3 million for the same period in 2023. The $1.7 million decrease was primarily due to reduced personnel and travel expenses related to sales force restructuring activities completed during the quarter. General and administrative expenses for the first quarter of 2024 were $10.7 million compared to $10.5 million for the same period in 2023. The $0.2 million increase was primarily attributable to a loss of $1.2 million related to estimated returns associated with sales of V-Go that pre-date our acquisition of the product, partially offset by reduced personnel costs. Interest income, net, was $3.4 million for the first quarter of 2024 compared to $1.3 million for the same period in 2023. The $2.1 million increase was primarily due to higher yields on our securities portfolio and an increase in the underlying investments from the proceeds of the sale of 1% of our Tyvaso DPI royalties in December 2023. Interest expense on notes was $2.6 million and interest expense on financing liability (related to the sale-leaseback of our Danbury manufacturing facility) was $2.4 million for the first quarter of 2024 and remained consistent with the same period in 2023. Interest expense on liability for sale of future royalties was $4.2 million for the first quarter of 2024 due to imputed interest and amortization of debt issuance costs on the liability recorded in connection with the sale of a portion of our future royalties in December 2023. Cash, cash equivalents and investments as of March 31, 2024 were $304.5 million. 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 measure 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 as adjusted for select non-cash items: 1% royalty on net revenues for Tyvaso DPI ("sold portion of royalty revenue") and interest expense on the related liability, stock-based compensation expense and (gain) loss on foreign currency transaction for the periods presented: Three Months Ended March 31, 2024 2023 Net Income Diluted EPS Net Loss Diluted EPS (In thousands except per share data) GAAP reported$10,630 $0.04 $(9,795) $(0.04)Select non-cash adjustments: Sold portion of royalty revenue (1) (2,265) (0.01) — — Interest expense on liability for sale of future royalties 4,248 0.01 — — Stock compensation 3,885 0.01 3,655 0.01 (Gain) loss on foreign currency transaction (1,399) — 954 0.01 Non-GAAP adjusted$15,099 $0.05 $(5,186) $(0.02)Weighted average shares used to compute net income (loss) per share – diluted 324,733 263,969 __________________________ (1) Represents the non-cash portion of the 1% royalty on net sales of Tyvaso DPI earned during 1Q 2024 which is remitted to the royalty purchaser and recognized as royalties from collaborations in our consolidated statements of operations.

The related interest expense for 1Q 2024 was $1,856 and resulted in adjusted net income of $12,486. These adjustments are only applied to periods with net income. (2) Diluted weighted average shares differs from basic due to the weighted average number of shares that would be outstanding upon conversion of our Senior convertible notes (44,120 shares) and Mann Group convertible note (3,370 shares), and exercise or vesting of outstanding share-based payments to employees (6,887 shares). These adjustments to weighted average shares are only applied to periods with net income.
