EXPLANATORY NOTE

This Amendment No. 2 (“Amendment No. 2”) amends and supplements the Schedule 13D filed with the Securities and Exchange Commission on behalf of Nantahala Capital Management, LLC, a Massachusetts limited liability company (“Nantahala”), Mr. Wilmot B. Harkey and Mr. Daniel Mack, the principals of Nantahala (collectively, the “Reporting Persons”) on May 26, 2023 (the “Original Schedule 13D”), relating to Common Stock, par value $0.0001 per share (the “Common Stock”), of Aytu BioPharma, Inc. a Delaware corporation (the “Issuer”) as previously amended by the Reporting Persons on June 13, 2023. Capitalized terms used but not defined in this Amendment No. 2 have the meanings set forth in the Original Schedule 13D as previously amended. Except as specifically provided herein, this Amendment No. 1 does not modify any of the information reported in the Original Schedule 13D as previously amended.

This Schedule 13D relates to Common Stock of the Issuer purchased by Nantahala through the accounts of certain private funds and managed accounts (collectively, the “Nantahala Investors”). Nantahala serves as the investment adviser to the Nantahala Investors and may direct the vote and dispose of the 1,086,812 shares of Common Stock held by the Nantahala Investors. As the principals of Nantahala, Mr. Harkey and Mr. Mack may direct the vote and disposition of the 1,086,812 shares of Common Stock held by the Nantahala Investors.

Item 4.

Purpose of the Transaction

Item 4 of the Original Schedule 13D is amended and supplemented as follows:

On June 14, 2024, the Nantahala Investors exercised their Tranche B warrants, paying approximately $1,296,114 to acquire Exchange Warrants entitling them to purchase 815,217 shares of Common Stock for $0.0001 per share. The Nantahala Investors may not exercise the Exchange Warrants if such exercise would result in the Nantahala Investors beneficially owning in excess of 9.99% of the outstanding shares of the Issuer’s Common Stock. The Exchange Warrants, which expire only when exercised in full, are in the same form as the Pre-Funded Warrant attached as Exhibit 4.1 to Pre-effective Amendment No. 1 to the Registration Statement on Form S-1, filed by the Issuer with the SEC on June 5, 2023.

Item 5.

Interest in Securities of the Issuer

Item 5 of the Original Schedule 13D is amended and restated as follows:

(a) The aggregate percentage of Common Stock beneficially owned by the Reporting Persons is based upon a total of 5,972,327 shares of Common Stock outstanding as of June 18, 2024, as reported by the Issuer in a Current Report filed with the SEC on Form 8-K on the same date.

Nantahala, as the investment adviser of the Nantahala Investors, may be deemed to beneficially own the 1,086,812 shares of Common Stock held by the Nantahala Investors, representing approximately 18.2% of the issued and outstanding shares of Common Stock of the Issuer.

In addition, Mr. Harkey and Mr. Mack, as principals of Nantahala, the investment adviser of the Nantahala Investors, may also be deemed to beneficially own the 1,086,812 shares of Common Stock beneficially held by the Nantahala Investors, representing approximately 18.2% of the issued and outstanding shares of Common Stock of the Issuer.

(b) Nantahala, Mr. Harkey and Mr. Mack have the shared power to vote and dispose of the Common Stock reported in this Schedule 13D.

(c) Other than the transactions reported herein, no Reporting Person or Other Officer has effected any transactions in the Common Stock of the Issuer since the Original 13D.

(d) The Nantahala Investors hold the shares of Common Stock reported herein, including more than 5% of the outstanding shares of Common Stock beneficially owned by the Reporting Persons but held by Blackwell Partners LLC - Series A. No person other than the Nantahala Investors is known to have the right to receive, or the power to direct the receipt of dividends from, or proceeds from the sale of, the Common Stock.
