Onconetix, Inc., the Cincinnati-based biopharmaceutical company, announced on Monday, October 26, that its board of directors has approved a one-for-ten reverse stock split of its outstanding common stock, effective at 12:01 a.m. Eastern Time on November 6, 2026.
Under the split, every ten shares of Onconetix common stock will be automatically exchanged into one share. The company said the move will reduce its outstanding shares from approximately 5,886,774, as of October 21, 2026, to approximately 588,677, before adjustments for fractional shares.
Onconetix stock will continue to trade on Nasdaq under the symbol ONCO, and the company has been assigned a new CUSIP number, 68237Q500, in connection with the split. The number of authorized shares will remain at 250,000,000, and the par value of the stock, $0.00001 per share, will not change.
Stockholders who would otherwise be entitled to receive fractional shares will instead receive cash payments in lieu of those fractional shares, the company said. Reverse splits consolidate a company’s share count and raise the per-share price, a step companies commonly take in connection with exchange listing requirements.
Onconetix is headquartered in Cincinnati and is listed among the publicly traded life-sciences companies based in southwest Ohio. The November 6 effective date means the consolidation takes place the same week as the November 3 general election, and shareholders will see the adjusted share count reflected when the split takes effect.
The announcement did not include any change to the company’s business operations, product pipeline or management. Investors holding shares through a broker or bank will have their accounts adjusted automatically when the split takes effect, while certificated holders will be handled through the company’s transfer process described in its filings.
The company announced the decision through a Globe Newswire release on Monday afternoon. No change to the company’s authorized capital structure beyond the consolidation was announced.
