Transaction to take Realbotix LLC, a premier social humanoid robot company, to the Nasdaq

Realbotix Corp. (TSXV:XBOT) (Frankfurt: 76M0.F) (OTC:XBOTF) ("Realbotix" or the "Parent Company"), a leading AI humanoid robot manufacturer for social tasks, is pleased to provide an update on its previously announced transaction to list Realbotix LLC ("RealLLC" or the "Subsidiary"), a wholly owned subsidiary of Realbotix, on the Nasdaq Capital Market via a reverse takeover transaction with Onconetix, Inc. (NASDAQ:ONCO) ("ONCO").

The proposed transaction will result in the robotics and AI business of RealLLC to be listed on Nasdaq, with the Parent Company (Realbotix) maintaining a 75–90% ownership stake. No action is required by existing Realbotix shareholders as there are no changes to the structure of the Parent Company. The transaction is expected to close by October 2026.

Benefits to Realbotix Shareholders:

Realbotix shareholders retain the upside potential of the enterprise robotics and AI business within RealLLC.
There are no shares being issued by the Parent Company nor is a share consolidation required in the proposed transaction.
Realbotix will appoint four out of five directors to the ONCO board of directors at close.
This transaction unlocks value in the commercial robotics and AI business held at RealLLC by separating it from the Parent Company's direct-to-consumer business.
The closing capital at ONCO provides non-dilutive financing to grow the commercial robotics and AI business.

"Once listed on the Nasdaq, there will be a clearer and more visible market value for the commercial robotics business and greater access to capital, institutional investors, and long-term growth opportunities," said Andrew Kiguel, CEO of Realbotix. "Importantly, existing Realbotix shareholders will continue to participate in the future upside of the commercial robotics division through ownership in the Nasdaq-listed entity."

"Onconetix is committed to completing the acquisition of Realbotix LLC. Every day we read more about AI and the role humanoid robots will play in our future," said David White, CEO of Onconetix. "This transaction will give Onconetix an opportunity to participate in this rapidly developing part of the market."

RealLLC is a Nevada based subsidiary of Realbotix, the Parent Company. RealLLC designs and manufactures AI-powered humanoid robots for use in consumer-facing social roles such as customer service, healthcare, education, hospitality, and entertainment. RealLLC's operations include an engineering division, AI software division, robotics patents, and intellectual property.

RealLLC is a leader in embodied and physical AI with technology that enables autonomous humanoid robot behavior and does not require teleoperation from a human to function.

The proposed transaction, first announced on February 12, 2026, remains subject to certain conditions precedent to closing, including the requisite approval of the ONCO shareholders and regulators.
