Neutral shareholder Written later 8.01

Onconetix, Inc. said its Board approved an additional one-for-ten reverse stock split of its common stock, which will bring the aggregate split ratio under the stockholder-approved authority to one-for-one hundred with a May 21, 2026 split. Shares are expected to begin trading on a split-adjusted basis on Nasdaq on November 6, 2026, under the existing symbol ONCO. The split reduces the share count but does not change any stockholder's percentage ownership, apart from cash paid for fractional shares.

  • Outstanding shares expected to fall from approximately 5.9 million to approximately 589,000
  • Combined with the May 21, 2026 split, the aggregate ratio is one-for-one hundred; new CUSIP 68237Q500 and symbol ONCO unchanged
  • No fractional shares will be issued; holders will receive cash in lieu, and authorized shares remain at 250,000,000

Onconetix lends up to $5.0 million to Realbotix ahead of pending share exchange

Neutral financing Written later 1.017.01

Onconetix agreed on September 11, 2026 to lend up to $5.0 million to Realbotix, LLC, the target of its pending all-stock acquisition, with $2.5 million advanced at signing. The loan is non-interest bearing until the acquisition closes or is terminated, and the balance is cancelled at closing, which reduces the cash Onconetix must hold at closing. For shareholders, the filing shows the financing terms but no change to the acquisition's status, which still requires Onconetix shareholder and regulatory approvals.

  • Loan of up to $5.0 million to Realbotix, with $2.5 million advanced on September 11, 2026; note matures September 11, 2027
  • Note is non-interest bearing until the Share Exchange Agreement closes or terminates; 12% annual interest accrues if terminated
  • At closing, the note is cancelled and the required Net Cash at Closing rises by $500,000 plus the outstanding principal
  • Realbotix Corp. guarantees the note; closing requires at least $12.5 million in Net Cash
