Notes to Financial Statements
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Note 1 - Nature of Business and Financial Condition Aytu BioPharma, Inc. (“Aytu,” the “Company,” “we,” “us,” or “our”), is a pharmaceutical company focused on advancing innovative medicines for complex central nervous system diseases to improve the quality of life for patients. The Company was originally incorporated as Rosewind Corporation on August 9, 2002, in the state of Colorado and was re-incorporated as Aytu BioScience, Inc. in the state of Delaware on June 8, 2015. In March 2021, the Company changed its name to Aytu BioPharma, Inc. The Company’s strategy is to become a leading pharmaceutical company that improves the lives of patients. The Company uses a focused approach of in-licensing, acquiring, developing and commercializing novel prescription therapeutics in order to continue building its portfolio of revenue-generating products and leveraging its commercial team’s expertise to build leading brands within large therapeutic markets. In June 2025, the Company entered into an Exclusive Commercialization Agreement (the “Commercialization Agreement”) with Fabre-Kramer Holdings, Inc. (“Fabre-Kramer”) to commercialize EXXUA (gepirone) extended-release tablets (“EXXUA”) in the United States. Gepirone is a new chemical entity, and the Company believes EXXUA to be a novel first-in-class selective serotonin 5HT1a receptor agonist approved by the United States Food and Drug Administration (“FDA”) for the treatment of major depressive disorder (“MDD”) in adults. It is the Company’s expectation that EXXUA has the potential to serve as a major growth catalyst for the Company and anticipates launching EXXUA in the fourth calendar quarter of 2025 as a centerpiece of its commercial efforts. In addition, the Company will continue to focus on commercializing innovative prescription products that address conditions frequently developed or diagnosed in children, including attention deficit hyperactivity disorder (“ADHD”). The Company is focusing its efforts on accelerating the growth of its commercial business and achieving positive operating cash flows. To achieve these goals, the Company indefinitely suspended active development of its clinical development programs and has wound down and divested unprofitable operations. In the first quarter of fiscal 2025 the Company completed the previously announced wind down of its Consumer Health business and on July 31, 2024, the Company entered into a definitive agreement to divest its Consumer Health business to a private, e-commerce focused company affiliated with the Company’s former Vice President of Consumer Health, Jonathan Hughes. Pursuant to the definitive agreement, Mr. Hughes resigned from the Company effective July 31, 2024. The divested business encompassed the established e-commerce platform, certain inventory and associated consumer brands, intellectual property, contracts and liabilities and provided for the Company to receive up to $0.5 million of revenue-based royalty payments and recovery of cost on certain future sales of former Consumer Health business products. The accounting requirements for reporting the Consumer Health business as a discontinued operation were met when the wind down and divestiture was completed on July 31, 2024. Accordingly, the Company’s consolidated financial statements for all periods presented reflect the Consumer Health business as a discontinued operation and the Company determined that its continuing operations now operate in a single operating and reportable segment (see Note 20 - Discontinued Operations and the Segment Information section within Note 2 - Summary of Significant Accounting Policies for further detail). The Company’s business from continuing operations is focused on the upcoming launch of EXXUA and on its current prescription pharmaceutical products sold primarily through third party wholesalers and pharmacies and which primarily consists of two product portfolios. The first primarily consists of two products for the treatment of ADHD: Adzenys XR-ODT (amphetamine) extended-release orally disintegrating tablets (“Adzenys”) and Cotempla XR-ODT (methylphenidate) extended-release orally disintegrating tablets (“Cotempla” and Adzenys together with Cotempla the “ADHD Portfolio”). The second primarily consists of Karbinal ER (carbinoxamine maleate extended-release oral suspension) (“Karbinal”), an extended-release first-generation antihistamine suspension containing carbinoxamine indicated to treat numerous allergic conditions, and Poly-Vi-Flor and Tri-Vi-Flor, two complementary prescription fluoride-based supplement product lines containing combinations of fluoride and vitamins in various formulations for infants and children with fluoride deficiency (the “Pediatric Portfolio”). During the fourth quarter of fiscal 2024, the Company successfully completed the transition of all manufacturing of its Adzenys and Cotempla products to a United States-based third-party contract manufacturer to improve the profitability of these products. In July 2023, the Company entered into an exclusive collaboration, distribution and supply agreement with Medomie Pharma Ltd (“Medomie”), a privately owned pharmaceutical company, for Medomie to commercialize Adzenys and Cotempla in Israel and the Palestinian Authority. In September 2024, the Company entered into an exclusive collaboration, distribution and supply agreement with Lupin Pharma Canada Ltd (“Lupin”), a subsidiary of global pharmaceutical company Lupin Limited, for Lupin to commercialize Adzenys and Cotempla in Canada. The Company will supply Adzenys and Cotempla to Medomie and Lupin based on forecasts and provide various product commercialization, regulatory and quality assurance resources. Medomie and Lupin are responsible for seeking local regulatory approvals and marketing authorizations for both Adzenys and Cotempla, which is expected to occur over the next 24 months. The agreements with Medomie and Lupin represent the Company’s first and second international commercial agreements for Adzenys and Cotempla, respectively.
