(NASDAQ: ONCO) (“Onconetix” or the “Company”), a commercial-stage biotechnology company focused on the research, development, and commercialization of innovative solutions for men’s health and oncology, today announced that its Board of Directors (the “Board of Directors” or “Board”) has approved a 1-for-5 reverse stock split of its outstanding shares of common stock, to be effective as of 12:01 a.m. Eastern Time on March 25, 2026.
On February 3, 2026, Onconetix held a special meeting of stockholders (the “Special Meeting”), at which the Company’s stockholders approved a proposal to effect a reverse split, at a ratio in the range of 1-for-2 to 1-for-50, at any time prior to the one-year anniversary date of the Special Meeting, with such ratio to be determined by the Board without further approval or authorization of the stockholders. Since the receipt of such stockholder approval, the Company’s Board of Directors has determined to fix a split ratio of 1-for-5 shares. The Company’s common stock will begin trading on a reverse stock split-adjusted basis at the opening of the market on March 25, 2026. Following the reverse stock split, the Company’s common stock will continue to trade on The Nasdaq Capital Market under the symbol “ONCO” under the new CUSIP number 68237Q 302.

At the effective time of the reverse split, every 5 issued and outstanding shares of the Company’s common stock will be converted automatically into one share of the Company’s common stock without any change in the par value per share. No fractional shares will be issued in connection with the reverse stock split, and fractional shares resulting from the reverse stock split will be canceled with the holders thereof receiving cash compensation. The amount of compensation will be determined by multiplying the fractional share by the closing price per share of the Company’s common stock on The Nasdaq Capital Market at the close of business on the trading day prior to the effective date of the reserve stock split, or March 24, 2026. The reverse split will have no effect on the number of authorized shares of the Company’s common stock, and the ownership percentage of each stockholder will remain unchanged other than as a result of fractional shares. The reverse stock split will additionally apply to the Company’s common stock issuable upon exercise or conversion of the Company’s equity awards, convertible preferred stock and warrants, as well as the applicable exercise price.
The reverse stock split will reduce the number of outstanding shares of the Company’s common stock from approximately 3.6 million to approximately 0.7 million.
