Onconetix Executes 1-for-10 Reverse Stock Split Effective November 6, 2026

Onconetix will consolidate every ten shares into one starting November 6, 2026, a move typically used to boost share price.

Onconetix, Inc. (Nasdaq: ONCO), a Cincinnati-based company, announced on October 26, 2026 that its Board of Directors has approved a 1-for-10 reverse stock split of its outstanding common stock. Under the terms, every ten shares a stockholder holds will be consolidated into a single share, which proportionally increases the per-share price without changing the overall market value of any individual's holdings. The reverse split is scheduled to take effect at 12:01 a.m. Eastern Time on November 6, 2026. In connection with the change, the company's common stock has been assigned a new CUSIP number — 68237Q500 — which is the identifier used by financial institutions to track the security. Reverse stock splits are a common mechanism companies use when their share price has fallen to levels that may put them at risk of failing to meet a stock exchange's minimum price requirements. Nasdaq, where ONCO trades, requires listed companies to maintain a minimum bid price of $1.00 per share. The sources do not explicitly state Onconetix's current share price or confirm a Nasdaq compliance notice as the trigger. No additional operational announcements accompanied the reverse split disclosure. The company did not issue guidance on business performance or pipeline updates alongside this filing.

Why it matters

Reverse stock splits often signal that a company's share price has fallen dangerously low, raising questions about financial health and the risk of delisting from Nasdaq. Existing shareholders will hold fewer shares after November 6, though the proportional value of their stake remains the same.

What's next

The reverse split takes effect at 12:01 a.m. Eastern Time on November 6, 2026, after which ONCO shares will trade under the new CUSIP number 68237Q500.

Bias & framing notes

All three sources carry identical text from a Globe Newswire press release, meaning this is a single-source corporate announcement republished across outlets rather than independently reported. The trust score reflects the reliability of a direct company filing while accounting for the absence of any independent journalistic verification or context about the company's financial condition.
