Pursuant to the Vetter MCSA, Vetter, through Vetter Pharma-Fertigung\nGmbH & Co. KG, has agreed to manufacture one or more application systems pre-filled with an active pharmaceutical ingredient, placebo\nor other material for the Company. The Company and Vetter previously entered into a master development agreement, effective as of October\n27, 2021, under which Vetter performed development and manufacturing services related to the Company’s product candidate sonelokimab.\n\n \n\nThe\nVetter MCSA is structured as a master agreement under which the parties may enter into product-specific schedules (each, a “Product\nSchedule”) from time to time, each detailing the specific manufacturing services and pricing applicable to a particular product.\nThe Company has agreed to pay Vetter the prices set forth in each Product Schedule. For each Product Schedule, Vetter may, subject to\nlimitations, adjust its prices based upon reasonable and documented information reflecting increases in Vetter’s cost structure,\nincluding wages, insurance, energy costs and other associated costs and expenses, as well as increases in costs of materials supplied\nor services provided by any third party.\n\n \n\nThe\nVetter MCSA shall remain in full force and effect until terminated. Either party may terminate the Vetter MCSA or any Product Schedule\nfor cause in the event of a material breach by the other party that has not been cured within 60 calendar days of receiving written notice\nof such breach. Either party may also terminate the Vetter MCSA without cause upon 12 months’ written notice, with immediate effect\nat any time when all existing Product Schedules have been terminated. Vetter may terminate the Vetter MCSA if the Company is the subject\nof a “Change of Control” (as defined in the Vetter MCSA) by an acquirer that is not a reputable pharmaceutical company meeting\ncertain specified criteria, and the Company may terminate the Vetter MCSA if Vetter is taken over by a competitor of the Company that\nis active within the sector of development of dermatology and inflammatory diseases, including rheumatology, before the end of 2029.\nEither party may terminate the Vetter MCSA with immediate effect due to the other party’s bankruptcy or insolvency. The Vetter\nMCSA includes customary provisions relating to, among others, procedures for defective products, delivery, inspection and acceptance\nprocedures, manufacturing facilities, regulatory matters, intellectual property rights, and confidentiality.\n\n \n\nAlso\non May 22, 2026, the Company and Vetter entered into a Capacity Agreement (the “Vetter Capacity Agreement”), under which\nthe Company is required to provide Vetter with its aggregate demand for a product for a certain period, with the annual demands for the\ninitial term of such forecast constituting a binding capacity reservation commitment (the “MoonLake Commitment”). The MoonLake\nCommitment may not be increased without Vetter’s prior written consent (the quantity so specified being the “Maximum Quantity”)\nand may not be decreased below specified floors (the “Minimum Quantity”). Vetter has committed to reserve filling capacity\nequivalent to the Maximum Quantity per year for the agreed binding period. The Company may be obligated to pay capacity compensation\nto Vetter if the Company fails to order the Minimum Quantity commitment or fails to provide purchase orders for the agreed binding period.\nPursuant to the Vetter Capacity Agreement, the Company may, depending on the timing and amount of reduced aggregate demand, if any, be\nobligated to pay Vetter for a portion of lost net revenue, subject to certain limitations.\n\n \n\nThe\nabove descriptions of the Vetter MCSA and Vetter Capacity Agreement are summaries only and are qualified in their entirety by reference\nto the Vetter MCSA and Vetter Capacity Agreement, which will be filed as exhibits to the Company’s Quarterly Report on Form 10-Q\nfor the quarter ending June 30, 2026.\n\n \n\n1\n\n \n\n**SIGNATURE**\n\n \n\nPursuant\nto the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by\nthe undersigned hereunto duly authorized.\n\n \n\n \n**MOONLAKE\nIMMUNOTHERAPEUTICS**\n\n \n \n\nDate: June 1, 2026\nBy:\n/s/\nMatthias Bodenstedt\n\n \nName:\nMatthias\nBodenstedt\n\nTitle:\nChief\nFinancial Officer\n\n \n\n****\n\n2\n\n** **"}
