• Company Expects a Six-Month Review of the Prior Approval Supplement Submission by the U.S. Food & Drug Administration Which, if Approved, Enables the Transfer of Cotempla Production to Contract Manufacturer
• Upon Completion of Manufacturing Transfer of Adzenys XR-ODT and Cotempla XR-ODT, Company Expects to Improve ADHD Product Margins by an Estimated Fifteen Percent

ENGLEWOOD, CO / ACCESSWIRE / July 10, 2023 / Aytu BioPharma, Inc. (the Company or "Aytu") (NASDAQ:AYTU), a pharmaceutical company focused on developing and commercializing novel therapeutics, has submitted the Cotempla XR-ODT® ("Cotempla") Prior Approval Supplement (PAS) to the U.S. Food & Drug Administration (FDA). If approved, the PAS would enable Aytu to transfer the production of Cotempla to the Company's third-party manufacturer. The Company expects a six-month review of the PAS submission, which would enable FDA approval by late calendar 2023 or early calendar 2024. The Company previously announced the FDA approval of the Adzenys XR-ODT® ("Adzenys") site transfer PAS and has begun shifting Adzenys production to the Company's contract manufacturer.

"I'm pleased to report this additional milestone as we work to increase the profitability of our products by reducing the cost of goods sold and the expenses associated with the production of our ADHD products by leveraging the operating efficiencies of our contract manufacturer," commented Josh Disbrow, Aytu's Chief Executive Officer. "With this additional step now achieved, we have even greater visibility into the timing of the site transfer and expect to begin outsourced manufacturing of Adzenys and Cotempla by late 2023 or early 2024. Importantly, we have already begun shifting production of Adzenys to Aytu's contract manufacturer. Thus, we expect to start realizing margin improvements for the ADHD brands in early calendar 2024. As we have previously communicated, upon the completion of the site transfers of both products and exiting the former Neos Therapeutics Grand Prairie, Texas facility, we expect to realize an estimated fifteen percent margin improvement of the ADHD brands. I am grateful for our team's tremendous effort and applaud their hard work in advancing the site transfer of these important brands."
