Onconetix plans a 1-for-10 reverse stock split for its shares

what happened

Onconetix, Inc. has announced that its board of directors approved a one-for-ten reverse split of its common stock. Adjusted trading is set to begin at 12:01 a.m. Eastern Time on November 6, 2026, and the shares will keep trading on Nasdaq under the ticker ONCO, though they will carry a new CUSIP, 68237Q500. Every ten existing shares will convert into a single share. Based on the roughly 5,886,774 shares outstanding on October 21, 2026, the count would fall to about 588,677 before fractional-share adjustments.

No fractional shares will be issued; holders entitled to them will receive cash instead. The authorized share count stays at 250,000,000 and par value at $0.00001. Options, warrants and convertible instruments will be adjusted proportionally, while shareholder rights remain unchanged.

why it matters

Reverse splits are usually a housekeeping step to lift a stock's nominal price, and they do not by themselves change an investor's stake in the company. The release contains no new financial results, so for the broader market this is a minor corporate event. For ONCO holders, the key items are the new share count and the date the change takes effect.
