Explanatory Note

This Current Report on Form 8-K/A (this “Amended 8-K”) amends and restates the Current Report on Form 8-K filed by VolitionRx Limited (the “Company”) with the Securities and Exchange Commission on November 7, 2025 (the “Original Report”). The Company is filing this Amended 8-K to replace Exhibit 1.1 in the Original Report with Exhibit 1.1 attached to this Amendment. Exhibit 1.1 attached hereto corrects typographical errors contained in Exhibit 1.1 to the Original Report and supersedes it in its entirety.

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 (the “Closing 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 at a combined offering price to the public of $0.52 per share of Common Stock and accompanying common stock warrant to purchase one share of Common Stock, including $0.01 per common stock warrant, less an underwriting commission 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 same price per share and accompanying warrant.

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 the Option Shares, the Option Warrants, or any combination thereof, rather than solely as a single, combined exercise for both. 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 per share and accompanying warrant as in the Offering, which 1,732,500 Option Warrants are exercisable for up to 83,580 shares.

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.
