NOTE
This Current
Report on Form 8-K/A (this “Amendment”) amends the Current Report on Form 8-K of Actinium Pharmaceuticals, Inc. (the “Company”)
filed with the U.S. Securities and Exchange Commission on November 26, 2025 (the “Original Form 8-K”). The Original Form 8-K
reported the final voting results of the Company’s Annual General Meeting of Shareholders held on November 26, 2025 (the “Annual
Meeting”). The sole purpose of this Amendment is to disclose the Company’s decision regarding how frequently it will conduct
future shareholder advisory votes to approve the compensation of the Company’s named executive officers (“Say-on-Pay Vote(s)”)
in accordance with Item 5.07(d) of Form 8-K. No other changes have been made to the Original Form 8-K.
Item 5.07
Submission of Matters to a Vote of Security Holders
As previously
reported in the Original Form 8-K, in an advisory vote held at the Annual Meeting on the frequency of future Say-on-Pay Votes, the Company’s
shareholders expressed their preference for a Say-on-Pay Vote to be conducted every year. On March 20, 2026, the Company’s board
of directors considered the outcome of this advisory vote and determined that future Say-on-Pay Votes will be conducted every year. The
Company’s board of directors will re-evaluate this determination after the next shareholder advisory vote on the frequency of Say-on-Pay
Votes (which will be at the 2031 Annual General Meeting of Shareholders, unless presented earlier).
