Explanatory Note

This Current Report on Form 8-K/A (this “Amended 8-K”) amends and restates in its entirety the Current Report on Form 8-K filed by VolitionRx Limited (the “Company”) with the Securities and Exchange Commission on November 7, 2025 (as amended, the “Prior Report”). The Company is filing this Amended 8-K to correct a typographical error in Item 1.01 in the Prior Report.

Item 1.01 Entry into a Material Definitive Agreement.

As previously reported, on October 10, 2025, the Company entered into an Underwriting Agreement (the “Underwriting Agreement”) with Newbridge Securities Corporation (the “Underwriter”), relating to an underwritten public offering of 11,550,000 shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), together with accompanying common stock purchase warrants to purchase up to an aggregate of 11,550,000 shares of Common Stock. Each share of Common Stock was offered and sold together with an accompanying common stock warrant to purchase one share of Common Stock at a combined offering price to the public of $0.52, including $0.01 per common stock warrant, less an underwriting discount of 7.0% (the “Offering”). Pursuant to the terms of the Underwriting Agreement, the Company also granted the Underwriter a 30-day option (the “Over-Allotment Option”) to purchase up to an additional 1,732,500 shares of Common Stock (the “Option Shares”), as well as accompanying common stock purchase warrants to purchase up to an aggregate of 1,732,500 shares of Common Stock (the “Option Warrants”) at the combined offering price to the public.

On November 7, 2025, the Company and the Underwriter entered into an amendment to the Underwriting Agreement (the “Amendment”) to modify the terms of the Over-Allotment Option. The Amendment permits the Underwriter, in its sole discretion, to exercise the Over-Allotment Option with respect to solely Option Shares, solely Option Warrants, or any combination thereof, rather than only as a combined exercise for both Option Shares and Option Warrants together. Concurrently with the execution of the Amendment, the Underwriter exercised its Over-Allotment Option to purchase 1,194,000 Option Shares and 1,732,500 Option Warrants at the same price to public as in the Offering, allocated as $0.51 per share and $0.01 per warrant, less an underwriting discount of 7.0%, for net proceeds to the Company of $582,426 after deducting expenses payable.

In connection with the Underwriter’s exercise of the Over-Allotment Option and pursuant to the Underwriting Agreement, the Company also issued to the Underwriter warrants to purchase up to an aggregate 83,580 shares of Common Stock, or 7.0% of the number of 1,194,000 Option Shares sold in the Over-Allotment Option (the “Underwriter Warrants”), at an exercise price of $0.63 per share. The Underwriter Warrants are in substantially the same form as the Option Warrants and are exercisable at any time during the period commencing six months after their issuance and expire five years after the closing date of the Offering.

The foregoing description of the terms of the Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Amendment, a copy of which is filed as Exhibit 1.1 hereto and incorporated herein by reference.
