On July 30, 2024, the Company received a letter from Nasdaq staff (the “Nasdaq Letter”) stating that the staff had determined that the Company’s acquisition of Proteomedix AG constitutes a business combination that results in a “Change of Control” pursuant to Nasdaq Listing Rule 5110(a), and that, as a result, the Company will be required to satisfy all of Nasdaq’s initial listing criteria and to complete Nasdaq’s initial listing process prior to the conversion of the Series B Preferred Stock, or other material changes triggering a change of control. Among other things, Nasdaq’s initial listing criteria require a minimum price per share of at least $4.00 (the “Minimum Price Rule”).

Supplement to the Definitive Proxy Statement

On August 1, 2024, Onconetix, Inc. (the “Company”) filed a definitive proxy statement (the “Definitive Proxy Statement”) for the solicitation of proxies in connection with an annual meeting of the Company’s stockholders to be held on September 5, 2024 (the “Annual Meeting”) to consider and vote on, among other proposals, an amendment that would authorize, but not obligate, the board of directors (the “Board”) to amend the Company’s Certificate of Incorporation to effect a reverse stock split of the outstanding and treasury shares of Company common stock (“Common Stock”) at a ratio in the range of 1-for-30 to 1-for-60, which ratio would be subject to the Board’s discretion following stockholder approval (the “Reverse Stock Split”).

In view of the Nasdaq Letter, the Company has determined to supplement certain information contained in the Definitive Proxy Statement to provide updates with respect to the Company’s Nasdaq compliance status, the reasons for the Reverse Split Proposal, and related risks.

SUPPLEMENT TO THE DEFINITIVE PROXY STATEMENT OF

ONCONETIX, INC.

Dated September 3, 2024

The Company is providing additional information to its stockholders, as described in this supplement to the Definitive Proxy Statement filed with the United States Securities and Exchange Commission on August 1, 2024, in connection with the Annual Meeting to be held on September 5, 2024. These disclosures should be read in connection with the Definitive Proxy Statement, which should be read in its entirety. To the extent that the information set forth herein differs from or updates information contained in the Definitive Proxy Statement, the information set forth herein shall supersede or supplement the information in the Definitive Proxy Statement. Defined terms used but not defined herein have the meanings set forth in the Definitive Proxy Statement. The Company makes the following supplemental disclosures.

The following disclosure amends and restates the question in the section entitled “Frequently Asked Questions” on page vii to the Definitive Proxy Statement as set forth below.

Why should I vote for the Reverse Stock Split Proposal?

On September 18, 2023, we received notice from Nasdaq staff indicating that, based upon the closing bid price of the Common Stock for the prior 30 consecutive business days, we were not in compliance with the requirement to maintain a minimum bid price of $1.00 per share for continued listing on Nasdaq, as set forth in Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Rule”). On March 13, 2024, we submitted a plan of compliance to Nasdaq to discuss our plans to evidence compliance with the Bid Price Rule and we received an additional 180-day period, or until September 16, 2024, to regain compliance with the Bid Price Rule.

To regain compliance with the Bid Price Rule and qualify for continued listing on the Nasdaq Capital Market, the closing bid price per share of our common stock must be at least $1.00 for at least 10 consecutive business days on or prior to September 16, 2024. The Nasdaq Staff retains discretion to extend this 10-business day period to determine that the Company has demonstrated an ability to maintain long-term compliance.

If we do not regain compliance with the Bid Price Rule by the end of the second compliance period, our Common Stock will become subject to delisting. In the event that we receive notice that our Common Stock is being delisted, the Nasdaq listing rules permit us to appeal a delisting determination by Nasdaq to a hearings panel, but there can be no assurance that the panel would grant the Company’s request for continued listing.

Additionally, on July 30, 2024, the Company received a letter from Nasdaq staff stating that the staff had determined that the Company’s acquisition of Proteomedix AG constitutes a business combination that results in a “Change of Control” pursuant to Nasdaq Listing Rule 5110(a), and that, as a result, the Company will be required to satisfy all of Nasdaq’s initial listing criteria and to complete Nasdaq’s initial listing process prior to the conversion of the Series B Preferred Stock, or other material changes triggering a change of control. Among other things, Nasdaq’s initial listing criteria require a minimum price per share of at least $4.00 (the “Minimum Price Rule”).

The Board believes that the failure of stockholders to approve the Reverse Stock Split Amendment could prevent the Company from complying with the Bid Price Rule and the Minimum Price Rule and could, among other risks, inhibit our ability to conduct capital raising activities. If the Nasdaq Stock Market delists the Common Stock, then the Common Stock would likely become traded on an over-the-counter market such as that maintained by OTC Markets Group Inc., which does not have the substantial corporate governance or quantitative requirements for continued listing that the Nasdaq Stock Market has. In that event, interest in Common Stock may decline and certain institutions may not have the ability to trade in the Common Stock, all of which could have a material adverse effect on the liquidity or trading volume of the Common Stock. If the Common Stock becomes significantly less liquid due to delisting from the Nasdaq Stock Market, the Company’s stockholders may not have the ability to liquidate their investments in the Common Stock as and when desired, and the Company believes its ability to maintain and obtain analyst coverage, attract investor interest, and have access to capital may become significantly diminished as a result.

The following disclosure amends and restates the subsection entitled “Nasdaq Compliance” on page 13 to the Definitive Proxy Statement as set forth below.

On September 18, 2023, we received notice from Nasdaq staff indicating that, based upon the closing bid price of the Common Stock for the prior 30 consecutive business days, we were not in compliance with the requirement to maintain a minimum bid price of $1.00 per share for continued listing on Nasdaq, as set forth in Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Rule”). On March 13, 2024, we submitted a plan of compliance to Nasdaq to discuss our plans to evidence compliance with the Bid Price Rule and we received an additional 180-day period, or until September 16, 2024, to regain compliance with the Bid Price Rule.

On August 22, 2023, we received a notice from Nasdaq that we were not in compliance with Nasdaq Listing Rule 5250(c)(1), which requires listed companies to timely file all required periodic financial reports with the SEC, given our failure to timely file our quarterly report on Form 10-Q for the quarter ended June 30, 2023. On October 20, 2023, we filed our Form 10-Q for the period ended June 30, 2023, and on November 1, 2023, we announced that we had regained compliance with Nasdaq Listing Rule 5250(c)(1).

On May 8, 2024, we received a notice from Nasdaq notifying us that we are not in compliance with Nasdaq’s continued listing standards as set forth in Listing Rule 5550(b)(1), which requires Nasdaq-listed companies to maintain a minimum of $2,500,000 in stockholders’ equity for continued listing (the “Minimum Stockholders’ Equity Requirement”), because our stockholders’ equity for the fiscal year ended December 31, 2023 as reported in the our Annual Report on Form 10-K filed with the SEC on April 1, 2024 was $1,404,476, and as of the date of the notice, we did not meet the alternatives to the Minimum Stockholders’ Equity Requirement of having either (i) a market value of listed securities of at least $35 million or (ii) net income from continuing operations of at least $500,000 in the fiscal year ended December 31, 2023 or in two of the three most recently completed fiscal years. The notice received has no immediate effect on the Company’s Nasdaq listing.

On June 24, 2024, we submitted to Nasdaq our plan to achieve and sustain compliance with the Nasdaq Listing Rules. On July 30, 2024, Nasdaq granted us an extension until November 4, 2024, to regain compliance with the Minimum Stockholders' Equity Requirement. If we fail to timely regain compliance with the Minimum Stockholders’ Equity Requirement (including, to the extent granted by Nasdaq, any applicable extensions of time), our securities will be subject to delisting on Nasdaq.

Additionally, on July 30, 2024, we received a letter from Nasdaq staff stating that the staff had determined that our acquisition of Proteomedix constitutes a business combination that results in a “Change of Control” pursuant to Nasdaq Listing Rule 5110(a), and that, as a result, we will be required to satisfy all of Nasdaq’s initial listing criteria and to complete Nasdaq’s initial listing process prior to the conversion of the Series B Preferred Stock, or other material changes triggering a change of control. Such initial listing standards include, but are not limited to, the Minimum Price Rule, minimum stockholders’ equity of $5,000,000, and minimum market value of publicly held securities of $15,000,000. In order to assist with satisfying applicable listing standards, we intend to release a portion of the Exchange Shares and the Conversion Shares from the Lock-Up Agreement and to effect the Reverse Stock Split.

The following disclosure amends and restates the risk factor entitled “There can be no assurance that we will be able to comply with the continued listing standards of Nasdaq” on page 135 to the Definitive Proxy Statement as set forth below.

There can be no assurance that we will be able to comply with the applicable listing standards of Nasdaq.

Our eligibility for listing on Nasdaq depends on our ability to comply with Nasdaq’s applicable listing requirements.

On September 18, 2023, we received notice from Nasdaq staff indicating that, based upon the closing bid price of the Common Stock for the prior 30 consecutive business days, we were not in compliance with the requirement to maintain a minimum bid price of $1.00 per share for continued listing on Nasdaq, as set forth in Nasdaq Listing Rule 5550(a)(2). We have 180 days from September 18, 2023, or through March 16, 2024, to regain compliance with the Bid Price Rule. On March 13, 2024, we submitted a plan of compliance to Nasdaq to discuss our plans to evidence compliance with the Bid Price Rule and we received an additional 180-day period, or until September 16, 2024, to regain compliance with the Bid Price Rule.

On May 8, 2024, we received a notice from Nasdaq notifying us that we are not in compliance with Nasdaq’s continued listing standards as set forth in Listing Rule 5550(b)(1), which requires Nasdaq-listed companies to maintain a minimum of $2,500,000 in stockholders’ equity for continued listing, because our stockholders’ equity for the fiscal year ended December 31, 2023 as reported in the our Annual Report on Form 10-K filed with the SEC on April 11, 2024 was $1,404,476, and as of the date of the notice, we did not meet the alternatives to the Minimum Stockholders’ Equity Requirement of having either (i) a market value of listed securities of at least $35 million or (ii) net income from continuing operations of at least $500,000 in the fiscal year ended December 31, 2023 or in two of the three most recently completed fiscal years. The notice received has no immediate effect on the Company’s Nasdaq listing.

On June 24, 2024, we submitted to Nasdaq our plan to achieve and sustain compliance with the Nasdaq Listing Rules. On July 30, 2024, Nasdaq granted us an extension until November 4, 2024, to regain compliance with the Minimum Stockholders' Equity Requirement. If we fail to timely regain compliance with the Minimum Stockholders’ Equity Requirement (including, to the extent granted by Nasdaq, any applicable extensions of time), our securities will be subject to delisting on Nasdaq.

Additionally, on July 30, 2024, we received a letter from Nasdaq staff stating that the staff had determined that our acquisition of Proteomedix constitutes a business combination that results in a “Change of Control” pursuant to Nasdaq Listing Rule 5110(a), and that, as a result, we will be required to satisfy all of Nasdaq’s initial listing criteria and to complete Nasdaq’s initial listing process prior to the conversion of the Series B Preferred Stock, or other material changes triggering a change of control. Such initial listing standards include, but are not limited to, the Minimum Price Rule, minimum stockholders’ equity of $5,000,000, and minimum market value of publicly held securities of $15,000,000. In order to assist with satisfying applicable listing standards, we intend to release a portion of the Exchange Shares and the Conversion Shares from the Lock-Up Agreement and to effect the Reverse Stock Split.

If Nasdaq delists our common stock from trading on its exchange for failure to meet the Bid Price Rule, the Minimum Price Rule, the Minimum Stockholders’ Equity Requirement, or all other applicable listing standards, we and our stockholders could face significant material adverse consequences including: 

The following disclosure amends and restates the subsection entitled “Reasons for the Reverse Stock Split Proposal” on page 156 to the Definitive Proxy Statement as set forth below.

Reasons for the Reverse Stock Split Proposal

The Board is recommending to the Company’s stockholders for their approval an amendment that would authorize, but not obligate the Board, to amend the Company’s Certificate of Incorporation to effect a reverse stock split of the outstanding and treasury shares of Common Stock at a ratio in the range of 1-for-30 to 1-for-60, which ratio would be subject to the Board’s discretion following stockholder approval (the “Reverse Stock Split”). The Company believes that the availability of a range of reverse split ratios will provide the Company with the flexibility to implement the Reverse Stock Split, if effected at all, in a manner designed to maximize the anticipated benefits for the Company and its stockholders. The general description of the reverse split amendment set forth below is a summary only and is qualified in its entirety by and subject to the full text of the form of proposed amendment which is attached as Annex A hereto.

The Board’s primary objective in asking for authority to effect a reverse split is to increase the per-share trading price of our Common Stock. If our Board does not implement the Reverse Stock Split prior to the one-year anniversary of the date on which the Reverse Stock Split is approved by the Company’s stockholders at the Annual Meeting, the authority granted in this proposal to implement the Reverse Stock Split will terminate and the Reverse Stock Split Amendment will be abandoned.

On September 18, 2023, we received notice from Nasdaq staff indicating that, based upon the closing bid price of the Common Stock for the prior 30 consecutive business days, we were not in compliance with the requirement to maintain a minimum bid price of $1.00 per share for continued listing on Nasdaq, as set forth in Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Rule”). On March 13, 2024, we submitted a plan of compliance to Nasdaq to discuss our plans to evidence compliance with the Bid Price Rule and we received an additional 180-day period, or until September 16, 2024, to regain compliance with the Bid Price Rule.

To regain compliance with the Bid Price Rule and qualify for continued listing on the Nasdaq Capital Market, the closing bid price per share of our common stock must be at least $1.00 for at least 10 consecutive business days on or prior to September 16, 2024. The Nasdaq Staff retains discretion to extend this 10-business day period to determine that the Company has demonstrated an ability to maintain long-term compliance.

If we do not regain compliance with the Bid Price Rule by the end of the second compliance period, our Common Stock will become subject to delisting. In the event that we receive notice that our Common Stock is being delisted, the Nasdaq listing rules permit us to appeal a delisting determination by Nasdaq to a hearings panel, but there can be no assurance that the panel would grant the Company’s request for continued listing.

Additionally, on July 30, 2024, the Company received a letter from Nasdaq staff stating that the staff had determined that the Company’s acquisition of Proteomedix AG constitutes a business combination that results in a “Change of Control” pursuant to Nasdaq Listing Rule 5110(a), and that, as a result, the Company will be required to satisfy all of Nasdaq’s initial listing criteria and to complete Nasdaq’s initial listing process prior to the conversion of the Series B Preferred Stock, or other material changes triggering a change of control. Among other things, Nasdaq’s initial listing criteria require a minimum price per share of at least $4.00 (the “Minimum Price Rule”).

The Board believes that the failure of stockholders to approve the Reverse Stock Split Amendment could prevent the Company from complying with both the Bid Price Rule and the Minimum Price Rule and could, among other risks, inhibit our ability to conduct capital raising activities. If the Nasdaq Stock Market delists the Common Stock, then the Common Stock would likely become traded on an over-the-counter market such as that maintained by OTC Markets Group Inc., which does not have the substantial corporate governance or quantitative requirements for continued listing that the Nasdaq Stock Market has. In that event, interest in Common Stock may decline and certain institutions may not have the ability to trade in the Common Stock, all of which could have a material adverse effect on the liquidity or trading volume of the Common Stock. If the Common Stock becomes significantly less liquid due to delisting from the Nasdaq Stock Market, the Company’s stockholders may not have the ability to liquidate their investments in the Common Stock as and when desired, and the Company believes its ability to maintain and obtain analyst coverage, attract investor interest, and have access to capital may become significantly diminished as a result.
