QuESTIONS AND ANSWERS

Following are some commonly asked questions raised by our stockholders and answers to each of those questions.

What is a proxy?

A proxy is another person that you legally designate to vote your stock. If you designate someone as your proxy in a written document, that document is also called a "proxy" or a "proxy card." If you are a "street name" holder, you must obtain a proxy from your broker or nominee in order to vote your shares in person at the Annual Meeting.

What is a proxy statement?

A proxy statement is a document that regulations of the SEC require that we give to you when we ask you to sign a proxy card to vote your shares at the Annual Meeting.

What may I vote on at the annual meeting?

At the Annual Meeting, stockholders will consider and vote upon the following matters:

Proposal 1: To elect each of Sandesh Seth and Jeffrey W. Chell as a Class II director to serve for a three-year term that expires at the 2027 Annual Meeting of Stockholders, or until his successor is elected and qualified or until his earlier resignation or removal, (the "Director Election Proposal"); and

Proposal 2: To ratify the appointment of Marcum LLP ("Marcum") as our independent registered public accounting firm for the fiscal year ending December 31, 2024, (the "Auditor Ratification Proposal").

To consider and act upon any other business as may properly come before the Annual Meeting or any postponement thereof.

How does the Board recommend that I vote on the proposals?

Our Board unanimously recommends that the stockholders vote "FOR" Proposals 1 and 2 being put before our stockholders at the Annual Meeting.

What should I do if I receive more than one set of voting materials?

You may receive more than one set of the proxy materials (consisting of this proxy statement, the accompanying Notice, our 2023 Annual Report and the proxy card) or voting instruction card. For example, if you hold your shares in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold shares. Similarly, if you are a stockholder of record and also hold shares in a brokerage account, you will receive a copy of the proxy materials, including a proxy card, for shares held in your name and a voting instruction card for shares held in "street name." Please complete, sign, date and return each proxy card and voting instruction card that you receive to ensure that all of your shares are voted.

What is the record date and what does it mean?

The record date to determine the stockholders entitled to notice of and to vote at the Annual Meeting is October 29, 2024 (the "Record Date"). The Record Date is established by the Board as required by Delaware law. On the Record Date, 31,195,891 shares of common stock were issued and outstanding.

Who is entitled to vote at the Annual Meeting?

Holders of common stock at the close of business on the Record Date may vote at the Annual Meeting.

What are the voting rights of the stockholders?

Each holder of common stock is entitled to one vote per share of common stock on each matter to be acted upon at the Annual Meeting. Our Certificate of Incorporation, as amended (the "Charter") does not provide for cumulative voting rights.

What happens if a change to the Annual Meeting is necessary due to exigent circumstances?

While as of the date of this proxy statement we are intending to hold the Annual Meeting in a physical format, as part of our precautions regarding infectious diseases such as the COVID-19, other cases that may qualify as force majeure events, or other situations that may require exercise of caution in the company's best judgement, we reserve the right to reconsider the date, time, and/or means of convening the Annual Meeting, including holding the Annual Meeting by means of remote communications. If we take this step, we will announce the decision to do so as soon as practicable via a press release that will also be filed with the SEC as proxy material, as well as by posting details on our website at https://www.actiniumpharma.com/. Please monitor our SEC filings and check our website regularly until the Annual Meeting for updated information.

What is the difference between a stockholder of record and a "street name" holder?

If your shares are registered directly in your name with Securities Transfer Corporation, the Company's stock transfer agent, you are considered the stockholder of record with respect to those shares. The Notice of Annual Meeting and the accompanying proxy materials have been sent directly to you by the Company.

If your shares are held in a stock brokerage account or by a bank or other nominee, the nominee is considered the record holder of those shares. You are considered the beneficial owner of these shares, and your shares are held in "street name." The Notice of Annual Meeting and the accompanying proxy materials would have been forwarded to you by your nominee. As the beneficial owner, you have the right to direct your nominee concerning how to vote your shares by using the voting instructions the nominee included in the mailing or by following such nominee's instructions for voting.

What is a broker non-vote?

Broker non-votes occur when shares are held indirectly through a broker, bank or other intermediary on behalf of a beneficial owner (referred to as held in "street name") and the broker submits a proxy but does not vote for a matter because the broker has not received voting instructions from the beneficial owner and either (i) the broker does not have discretionary voting authority on the matter or (ii) the broker chooses not to vote on a matter for which it has discretionary voting authority. Under the rules of the New York Stock Exchange that govern how brokers may vote shares for which they have not received voting instructions from the beneficial owner, brokers are permitted to exercise discretionary voting authority only on "routine" matters when voting instructions have not been timely received from a beneficial owner. Proposal 2 (the Auditor Ratification Proposal) is considered a "routine matter". Therefore, if you do not provide voting instructions to your broker regarding such proposal, your broker will be permitted to exercise discretionary voting authority to vote your shares on such proposal. In the absence of specific instructions from you, your broker does not have discretionary authority to vote your shares with respect to Proposal 1 (the Director Election Proposal).

How do I vote?

If you are a record holder, you may vote your shares at the Annual Meeting in person or by proxy. Whether you plan to attend the Annual Meeting or not, we urge you to vote by proxy. If you vote by proxy, the individuals named on the proxy card, or your "proxies," will vote your shares in the manner you indicate. You may specify whether your shares should be voted for or withheld for the nominees for director or should be voted for, against, or abstained with respect to the ratification of the appointment of the Company's independent registered public accountants. Voting by proxy will not affect your right to attend the Annual Meeting. If your shares are registered directly in your name through our transfer agent, Securities Transfer Corporation, or you have stock certificates registered in your name, you may submit a proxy to vote:

• By Internet or by telephone. Stockholders may vote via the Internet at www.AALvote.com/atnm or by phone (as per instructions on the proxy card). You will need the control number included on your proxy card.

• By mail. If you received one or more printed proxy cards by mail, you can vote by mail by completing, signing, dating and returning the enclosed proxy card applicable to your class of stock in the enclosed postage prepaid envelope. Your proxy will be voted in accordance with your instructions. If you sign the proxy card but do not specify how you want your shares voted, they will be voted as recommended by our Board.

• In person at the Annual Meeting. If you attend the Annual Meeting, you may deliver your completed proxy card in person or you may vote by completing a ballot, which will be available at the Annual Meeting. You are required to register in advance of the Annual Meeting if you plan to attend the Annual Meeting in person. If you wish to register in advance of the Annual Meeting, please contact our investor relations office by no later than November 20, 2024, by e-mail to [email protected], mail to Actinium Pharmaceuticals, Inc., 100 Park Avenue, 23rd Floor, New York, New York 10017, or telephone at (646) 677-3875.

Telephone and Internet voting facilities for all stockholders of record will be available 24-hours a day and will close at 11:59 p.m., Eastern Standard Time, on November 26, 2024.

The proxy is fairly simple to complete, with specific instructions on the electronic ballot, telephone or proxy card. By completing and submitting it, you will direct the proxies to vote your shares at the Annual Meeting in accordance with your instructions. The Board has appointed Sandesh Seth to serve as the proxy for the Annual Meeting.

If your shares are held in "street name" (held in the name of a bank, broker or other nominee who is the holder of record), you must provide the bank, broker or other nominee with instructions on how to vote your shares and can do so as follows:

• By Internet or by telephone. Follow the instructions you receive from the record holder to vote by Internet or telephone.

• By mail. You should receive instructions from the record holder explaining how to vote your shares.

• In person at the Annual Meeting. Contact the broker, bank or other nominee who holds your shares to obtain a broker's proxy card and bring it with you to the Annual Meeting. You will not be able to vote at the Annual Meeting unless you have a proxy card from your broker, bank or other nominee.

What happens if additional matters are presented at the Annual Meeting?

Other than the election of directors and the ratification of the appointment of our auditor, we are not aware of any other business to be acted upon at the annual meeting. If you grant a proxy, the person named as proxy holder, Sandesh Seth, our Chairman and Chief Executive Officer will have the discretion to vote your shares on any additional matters properly presented for a vote at the Annual Meeting.

What happens if I do not give specific voting instructions?

If you hold shares in your name and you sign and return a proxy card without giving specific voting instructions, your shares will be voted as recommended by our Board on all matters and as the proxy holder may determine in his discretion with respect to any other matters properly presented for a vote before the Annual Meeting. If you hold your shares through a stockbroker, bank or other nominee and you do not provide instructions on how to vote, your stockbroker or other nominee may exercise their discretionary voting power with respect to certain proposals that are considered as "routine" matters. Proposal 2 (the Auditor Ratification Proposal) is considered a routine matter, and thus your stockbroker, bank or other nominee may exercise their discretionary voting power with respect to Proposal 2. If the organization that holds your shares does not receive instructions from you on how to vote your shares on a non-routine matter, the organization that holds your shares will inform us that it does not have the authority to vote on these matters with respect to your shares. This is generally referred to as a "broker non-vote." In the absence of specific instructions from you, your broker does not have discretionary authority to vote your shares with respect to Proposal 1 (the Director Election Proposal). We encourage you to provide voting instructions to the organization that holds your shares by carefully following the instructions provided in the notice.

What is the quorum requirement for the annual meeting?

On October 29, 2024, the Record Date for determining which stockholders are entitled to vote, there were 31,195,891 shares of our common stock outstanding, which is our only class of voting securities. Each share of common stock entitles the holder to one vote on matters submitted to a vote of our stockholders. The holders of at least thirty-four percent (34%) in voting power of our outstanding shares of common stock as of the Record Date must be present at the Annual Meeting (in person or represented by proxy) in order to hold the Annual Meeting and conduct business. This is called a quorum. Your shares will be counted for purposes of determining if there is a quorum, even if you wish to abstain from voting on some or all matters introduced at the Annual Meeting, if you are present and vote in person at the Annual Meeting or have properly submitted a proxy card or voted by fax, by phone or by using the Internet. Broker votes on routine proposals will be counted for purposes of determining whether a quorum is present.

Who counts the votes?

All votes will be tabulated by Gary Siegel, our Vice President, Controller, the inspector of election appointed for the Annual Meeting. Each proposal will be tabulated separately.

How can I change my vote after I return my proxy card?

You may revoke your proxy and change your vote at any time before the final vote at the Annual Meeting. You may do this by signing a new proxy card with a later date, by voting on a later date by using the Internet (only your latest Internet proxy submitted prior to the Annual Meeting will be counted), or by attending the Annual Meeting and voting in person. However, your attendance at the Annual Meeting will not automatically revoke your proxy unless you vote at the Annual Meeting or submit a notice of revocation to the Company addressed to Steve O'Loughlin, at the Company's address above, which notice must be received before 5:00 p.m., Eastern Time, on November 26, 2024.

Is my vote confidential?

Proxy instructions, ballots and voting tabulations that identify individual stockholders are handled in a manner that protects your voting privacy. Your vote will not be disclosed either within our company or to third parties, except:

• as necessary to meet applicable legal requirements;

• to allow for the tabulation of votes and certification of the vote; and

• to facilitate a successful proxy solicitation.

Any written comments that a stockholder might include on the proxy card will be forwarded to our management.

Where can I find the voting results of the Annual Meeting?

The preliminary voting results will be announced at the Annual Meeting. The final voting results will be tallied by our Inspector of Elections and reported in a Current Report on Form 8-K which we will file with the SEC, within four business days of the date of the Annual Meeting.

How can I obtain a separate set of voting materials?

To reduce the expense of delivering duplicate voting materials to our stockholders who may have more than one Actinium Pharmaceuticals, Inc. stock account, we are delivering only one proxy statement to certain stockholders who share an address, unless otherwise requested. This practice, known as "householding." If you share an address with another stockholder and have received only one proxy statement, you may write or call us to request to receive a separate proxy statement. Similarly, if you share an address with another stockholder and have received multiple copies of the proxy statement, you may write or call us at the address and phone number below to request delivery

of a single copy of the proxy statement. For future annual meetings of stockholders, you may request separate proxy statements, or request that we send only one proxy statement to you if you are receiving multiple copies, by writing or calling us at:

Actinium Pharmaceuticals, Inc.
Attention: Steve O'Loughlin, Chief Financial Officer
100 Park Avenue, 23rd Floor
New York, New York 10017
Tel: (646) 677-3875

Stockholders who own shares through a bank, broker or other intermediary can request householding by contacting the intermediary.

We hereby undertake to deliver promptly, upon written or oral request, a copy of the proxy statement to a stockholder at a shared address to which a single copy of the document was delivered. Requests should be directed to the address or phone number set forth above.

Who pays for the cost of this proxy solicitation?

Our Board is asking for your proxy, and we will pay the costs of the solicitation of proxies. We may also reimburse brokerage firms and other persons representing beneficial owners of shares for expenses incurred in forwarding the voting materials to their customers who are beneficial owners and obtaining their voting instructions. In addition to soliciting proxies by mail, our Board members, officers and employees may solicit proxies on our behalf, without additional compensation, personally, electronically or by telephone. In addition, we have retained Alliance Advisors, LLC ("Alliance") to assist in the solicitation of proxies for a fee of $10,000 plus customary expenses.

Is this proxy statement the only way that proxies are being solicited?

No. In addition to the solicitation of proxies by use of the mail, officers and employees of the Company, as well as Alliance, the proxy solicitation firm hired by the Company, may solicit the return of proxies, either by mail, telephone, telecopy, e-mail or through personal contact. These officers and employees will not receive additional compensation for their efforts but will be reimbursed for out-of-pocket expenses. The fees of Alliance as well as the reimbursement of expenses of Alliance will be borne by the Company. Brokerage houses and other custodians, nominees and fiduciaries, in connection with shares of the common stock registered in their names, will be requested to forward solicitation material to the beneficial owners of shares of common stock.

How can I obtain a copy of Actinium Pharmaceuticals, Inc.'s Annual Report?

This proxy statement and the Annual Report are available for viewing, printing and downloading at https://web.viewproxy.com/actiniumpharma/2024. To view these materials, please have your 11-digit control number(s) available that appears on your proxy card. On this website, you can also elect to receive future distributions of our proxy statements and annual reports to stockholders by electronic delivery.

Additionally, you can find a copy of our Annual Report, which includes our financial statements, for the fiscal year ended December 31, 2023 on the website of the SEC, at www.sec.gov, or in the "SEC Filings" section of the "Investors" section of our website at www.actiniumpharma.com. You may also obtain a printed copy of our Annual Report, including our financial statements, free of charge, from us by sending a written request to: Actinium Pharmaceuticals, Inc., 100 Park Avenue, 23rd Floor, New York, NY 10017, attention: Chief Financial Officer.

What is the voting requirement to elect directors?

Assuming the presence of a quorum, directors are elected by a plurality of the votes cast in person or by proxy at the Annual Meeting and entitled to vote on the Director Election Proposal. "Plurality" means that the nominees receiving the greatest number of affirmative votes will be elected as directors, up to the number of directors to be chosen at the Annual Meeting. Withhold or broker non-votes will not affect the outcome of the election of directors.

What is the voting requirement to approve Proposal 2?

Assuming the presence of a quorum, Proposal 2 (the Auditor Ratification Proposal) will be approved if the affirmative vote of the holders of a majority in voting power of the shares present in person or by proxy and entitled to vote thereon at the Annual Meeting is obtained. An abstention is not an "affirmative vote," but an abstaining stockholder is considered "entitled to vote" at the Annual Meeting. Accordingly, an abstention will have the effect of a vote against Proposal 2. Brokers are considered "entitled to vote" because brokers have discretionary voting authority on Proposal 2. Because a broker non-vote is not an "affirmative vote," a broker non-vote will have the effect of a vote against Proposal 2.

Do I Have Dissenters' (Appraisal) Rights?

Appraisal rights are not available to our stockholders with any of the proposals described above to be brought before the Annual Meeting.

How can I communicate with the non-employee directors on the Actinium Pharmaceuticals, Inc. Board of Directors?

Our Board encourages stockholders and any interested parties who are interested in communicating directly with the non-employee directors as a group to do so by writing to the non-employee directors in care of our Chairman and Chief Executive Officer. Stockholders and any interested parties can send communications by mail to:

Sandesh Seth, Chairman and Chief Executive Officer
Actinium Pharmaceuticals, Inc.
100 Park Avenue, 23rd Floor
New York, New York 10017

Correspondence received that is addressed to the non-employee directors will be reviewed by our Chairman of the Board or his designee, who will regularly forward to the non-employee directors a summary of all such correspondence and copies of all correspondence that, in the opinion of our Chairman, deals with the functions of our Board or committees thereof or that our Chairman otherwise determines requires their attention. Directors may at any time review a log of all correspondence received by us that is addressed to the non-employee members of our Board and request copies of any such correspondence.

CORPORATE GOVERNANCE

Board of Directors

Our Board oversees our business affairs and monitors the performance of management. In accordance with our corporate governance principles, our Board does not involve itself in day-to-day operations. The directors keep themselves informed through discussions with the Chairman and Chief Executive Officer, other key executives, and by reading the reports and other materials that we send them and by participating in Board and committee meetings. Biographical information about our directors is provided in the section "Directors and Executive Officers".

Term of Office

Our directors are divided into three classes, designated Class I, Class II and Class III. Class I consists of two directors, Class II consists of two directors, and Class III consists of two directors.

The term of each director is set forth below or until their successors are duly elected:

Directors elected at each annual meeting are elected for a three-year term. Notwithstanding the foregoing, each director shall serve until his successor is duly elected and qualified, or until his retirement, death, resignation or removal.

Director Independence

We use the definition of "independence" of the NYSE American stock exchange to make this determination. We are listed on the NYSE American under the symbol "ATNM". NYSE American corporate governance rule Section 803(A)(2) provides that an "independent director" means a person other than an executive officer or employee of the company. No director qualifies as independent unless the issuer's board of directors affirmatively determines that the director does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Under the NYSE American director independence rules, Jeffrey W. Chell, David Nicholson, Ajit S. Shetty, Richard I. Steinhart, and June S. Almenoff are independent directors of the Company.

Board Leadership Structure and Role in Risk Oversight

Our Board currently consists of six directors, and the positions of Chairman of the Board and principal executive officer are filled by Mr. Sandesh Seth, coupled with a lead independent director position to further strengthen the leadership structure. The Board acknowledges that there are different leadership structures that could allow it to effectively oversee the management of the risks relating to the Company's operations. However, our Board believes that having Mr. Seth as the Chairman of the Board and the Chief Executive Officer provides an efficient and effective leadership model for the Company, as such structure allows our independent directors to share responsibility in leading the Board, while allowing Mr. Seth to focus primarily on managing the operations of Company.

David Nicholson has been serving as our lead independent director (the "Lead Independent Director") since September 2017. Our Lead Independent Director chairs the executive sessions of our Board meetings; provides feedback to the Chairman and Chief Executive Officer; if appropriate, and in coordination with executive management, is available for consultation and direct communication with major stockholders; and leads the Board's evaluation of the Chairman and Chief Executive Officer. We have a separate chair for each committee of our Board, all of whom are independent directors. The chairs of each committee report on the activities of their committees in fulfilling their responsibilities at the meetings of our Board.

Our Board is responsible for overseeing the Company's risk management processes. The Board receives reports from management concerning the Company's assessment of risks and considers the Company's risk profile. The Board focuses on the most significant risks facing the Company and the Company's general risk management strategy. In addition, as part of its oversight of our Company's executive compensation program, the Board considers the impact of such program, and the incentives created by the compensation awards that it administers, on our Company's risk profile. In addition, the Board, based on the Compensation Committee's review of all of our compensation policies and procedures, considers the incentives that they create and factors that may reduce the likelihood of excessive risk taking and determines whether they present a significant risk to our Company. The Board has determined that, for all employees, our compensation programs do not encourage excessive risk and instead encourage behaviors that support sustainable value creation.

No director, officer or other employee, agent or contractor of the Company may engage in short sales, which are defined as any transactions whereby one may benefit from a decline in the Company's stock price. Our directors, officers and employees are also prohibited from trading in our securities during certain designated blackout periods and otherwise while they are aware of material non-public information.

Anti-Hedging and Anti-Pledging Policies

BOARD COMMITTEES

* Indicates committee chair

Audit Committee

Our Audit Committee, which currently consists of three independent directors, provides assistance to our Board in fulfilling its legal and fiduciary obligations with respect to matters involving the accounting, financial reporting, internal control and compliance functions of the Company. The Board has determined that Mr. Steinhart is an "audit committee financial expert" as defined in Item 407(d)(5)(ii) of Regulation S-K. Our Audit Committee employs an independent registered public accounting firm to audit the financial statements of the Company and perform other assigned duties. Further, our Audit Committee provides general oversight with respect to the accounting principles employed in financial reporting and the adequacy of our internal controls. In discharging its responsibilities, our Audit Committee may rely on the reports, findings and representations of the Company's auditors, legal counsel, and responsible officers. Our Board has determined that all members of the Audit Committee are financially literate within the meaning of SEC rules and under the current listing standards of the NYSE American. The Audit Committee met four times during 2023. Each member of the Audit Committee was present at all of the Audit Committee meetings held during 2023.

Compensation Committee

Our Compensation Committee, which currently consists of three directors, establishes executive compensation policies consistent with the Company's objectives and stockholder interests. The Compensation Committee met two times and acted by unanimous written consent on one occasion during 2023. Each member of the Compensation Committee was present at all committee meetings held in 2023. Our Compensation Committee also reviews the performance of our executive officers and establishes, adjusts and awards compensation, including incentive-based compensation, as more fully discussed below. In addition, our Compensation Committee generally is responsible for:

• establishing and periodically reviewing our compensation philosophy and the adequacy of compensation plans and programs for our directors, executive officers and other employees;

• overseeing our compensation plans, including the establishment of performance goals under the Company's incentive compensation arrangements and the review of performance against those goals in determining incentive award payouts;

• overseeing our executive employment contracts, severance, change in control arrangements and/or similar plans;

• acting as administrator of any company stock option plans; and

• overseeing outside compensation consultants when engaged.

Our Compensation Committee periodically reviews the compensation paid to our non-employee directors and the principles upon which their compensation is determined. The Compensation Committee also periodically reports to the Board on how our non-employee director compensation practices compare with those of other similarly situated public corporations and, if the Compensation Committee deems it appropriate, recommends changes to our director compensation practices to our Board for approval.

Outside consulting firms retained by our compensation committee and management also will, if requested, provide assistance to the Compensation Committee in making its compensation-related decisions. The Compensation Committee paid consultant fees to StreeterWyatt of $22,000 during the year ended December 31, 2023. StreeterWyatt was instructed to provide support and analyses to the compensation committee and their services included development of a peer group regarding executive and director compensation.

Nominating and Corporate Governance Committee

Our Nominating and Corporate Governance Committee, which currently consists of three directors, is charged with the responsibility of reviewing our corporate governance policies and proposing potential director nominees to the Board for consideration. Our Board has determined that each member of our Nominating and Corporate Governance Committee qualifies, and David Nicholson, a former member of the Nominating and Corporate Governance Committee, when he served on the Nominating and Corporate Governance Committee, qualified as an "independent" member of the Board as defined by the rules and regulations of the SEC and the NYSE American. The Nominating and Corporate Governance Committee met once and acted by unanimous written consent on one occasion during 2023.

Our Nominating and Corporate Governance Committee's primary responsibilities and obligations include, among other things:

• overseeing the administration of our Code of Business Ethics and Conduct and related policies;

• leading the search for and recommending individuals qualified to become members of the Board, and selecting director nominees to be presented for election by the stockholders at each annual meeting;

• assessing the diversity of the Board and recommending any changes to the Board's composition;

• ensuring, in cooperation with the Compensation Committee, that no agreements or arrangements are made with directors or relatives of directors for providing professional or consulting services to us or our affiliate or individual officer or one of their affiliated, without appropriate review and evaluation for conflicts of interest;

• assessing the independence of directors annually and report to the Board;

• recommending to the Board for its approval, the leadership structure of the Board, including whether the Board should have an executive or non-executive Chairman, whether the roles of Chairman and Chief Executive Officer should be combined, and whether a Lead Director of the Board should be appointed; provided that such structure shall be subject to the bylaws of the Company then in effect;

• ensuring that Board members do not serve on more than six other for-profit public company boards that have a class of securities registered under the Exchange Act in addition to the Board;

• reviewing the Board's committee structure and to recommend to the Board for its approval directors to serve as members of each committee as well as recommendations for committee chairs;

• reviewing and recommending changes to procedures whereby stockholders may communicate with the Board;

• reviewing recommendations received from stockholders for persons to be considered for nomination to the Board;

• monitoring compliance with our corporate governance guidelines;

• developing and implementing an annual self-evaluation of the Board, both individually and as a Board, and of its committees;

Our Nominating and Corporate Governance Committee considers all qualified candidates identified by members of the Board, by senior management and by stockholders. The Committee follows the same process and uses the same criteria for evaluating candidates proposed by stockholders, members of the Board and members of senior management. When evaluating a candidate to serve on our Board, the members of our Nominating and Corporate Governance Committee consider items such as experience in the biotechnology sector, experience with public companies, executive managerial experience, operations and commercial experience, fundraising experience and contacts in the investment banking industry, personal and skill set compatibility with current Board members, industry reputation, knowledge of our company generally, and independence.

Our Amended and Restated Bylaws, as amended (the "Bylaws") contains provisions that address the process by which a stockholder may nominate an individual to stand for election to the Board at our annual meetings. To recommend a nominee for election to the Board, a stockholder must submit his or her recommendation to our Secretary at our corporate offices at 100 Park Avenue, 23rd Floor, New York, New York 10017. Such nomination must satisfy the notice, information and consent requirements set forth in our Bylaws and must be received by us prior to the date set forth under "Submission of Future Stockholder Proposals" below. A stockholder's recommendation must be accompanied by the information with respect to stockholder nominees as specified in our Bylaws, including among other things, the name, age, address and occupation of the recommended person, the proposing stockholder's name and address, the ownership interests of the proposing stockholder and any beneficial owner on whose behalf the nomination is being made (including the number of shares beneficially owned, any hedging, derivative, short or other economic interests and any rights to vote any shares) and any material monetary or other relationships between the recommended person and the proposing stockholder and/or the beneficial owners, if any, on whose behalf the nomination is being made.

Our approach toward Board diversity takes into consideration the overall composition and diversity of the Board and areas of expertise that director nominees may be able to offer, including business experience, knowledge, abilities, customer relationships and appropriate perspectives on environmental, social and governance matters. The Board recognizes the importance of diversity and the value it can bring to the Board's overall advice and oversight. In 2023, the Nominating and Corporate Governance Committee together with the Chairman and CEO, formally undertook a process, including engaging with executive search firms and Actinium's internal human resources department, to identify and evaluate qualified candidates to address the Board's diversity and composition. The Nominating and Corporate Governance met four times in 2024 to review the Board's composition and diversity. Our entire Board was involved in the process to evaluate new potential directors, which included reference checks and in-person meetings. In October 2024, we increased our Board to six members and effective November 2024, added Dr. June Almenoff as a Class III Director who also serves on our Nominating and Corporate Governance Committee. Generally, we strive to assemble and maintain a Board that brings to us a variety of perspectives and skills derived from business and professional experience as we may deem are in our and our stockholders' best interests. In doing so, we also consider candidates with appropriate non-business backgrounds.

AUDIT COMMITTEE REPORT

Report of the Audit Committee of the Board of Directors

The Audit Committee provides assistance to the Board in fulfilling its oversight responsibilities relating to our corporate accounting and reporting practices toward assurance of the quality and integrity of our consolidated financial statements. The purpose of the Audit Committee is to serve as an independent and objective party to monitor our financial reporting process and internal control system; oversee, review and appraise the audit activities of our independent registered public accounting firm and internal auditing function, maintain complete, objective and open communication between the Board, the independent accountants, financial management and the internal audit function.

Our independent registered public accounting firm reports directly to the Audit Committee, and the Audit Committee is solely responsible to appoint or replace our independent registered public accounting firm and to assure its independence and to provide oversight and supervision thereof. The Audit Committee determines compensation of the independent registered public accounting firm and has established a policy for approval of non-audit related engagements awarded to the independent registered public accounting firm. Such engagements must not impair the independence of the registered public accounting firm with respect to our Company as prescribed by the Sarbanes - Oxley Act of 2002; thus payment amounts are limited and non-audit related engagements must be approved in advance by the Audit Committee. The Audit Committee determines the extent of funding that we must provide to the Audit Committee to carry out its duties and has determined that such amounts were sufficient in 2022.

With respect to the fiscal year ended December 31, 2023, in addition to its other work, the Audit Committee:

• Reviewed and discussed with management our audited consolidated financial statements as of December 31, 2023 and for the year then ended;

• Discussed with Marcum the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board ("PCAOB") and the SEC; and

• Received the written disclosures and the letter from Marcum required by the applicable requirements of the PCAOB regarding the independent accountant's communications with the Audit Committee concerning independence and has discussed with Marcum its independence.

The Audit Committee recommended, based on the review and discussion summarized above, that the Board include the 2023 audited consolidated financial statements in the 2023 Form 10-K for the fiscal year ended December 31, 2023 for filing with the SEC.

Information About Our Auditors

Our Audit Committee of our Board appointed Marcum as the independent registered public accounting firm to conduct the audit of our consolidated financial statements for the 2023 fiscal year and to report on our consolidated balance sheets, statements of income and other related statements.

Fees and Services

The table below shows the aggregate fees billed for professional services for the audits and audit-related fees of the Company's annual financial statements included in Form 10-K for the years ending December 31, 2023 and 2022, respectively, by Marcum LLP (PCAOB ID Number 688).

Audit Fees. This category includes the audit of our annual consolidated financial statements, reviews of our financial statements included in our Form 10-Qs and services that are normally provided by our independent registered public accounting firm in connection with its engagements for those years.

Audit-Related Fees. This category consists of assurance and related services by our independent registered public accounting firm that are reasonably related to the performance of the audit or review of our financial statements and are not reported above under "Audit Fees." The services for the fees disclosed under this category include consents regarding equity issuances.

Pre-Approval Policy

In 2015, the Audit Committee adopted policies and procedures for the pre-approval of audit and non-audit services performed by the independent registered public accountants. Under the policies, the Audit Committee is required to pre-approve all audit services and permitted non-audit and tax services provided by the independent registered public accountants in order to ensure that the provision of such services does not impair the registered accountants' independence.

All of the services rendered by Marcum in 2023 were pre-approved by the Audit Committee.

____________

(1) The bonus disclosed in this column relates to performance in the prior year, but was determined and approved by the Board and was paid in the year disclosed.

(2) The dollar amounts in this column represent the aggregate grant date fair value of all option awards granted during the indicated year. These amounts have been calculated in accordance with FASB ASC Topic 718, using the Black-Scholes option-pricing model. For a discussion of valuation assumptions, see Note 7 to our financial statements in the Annual Report. These amounts do not correspond to the value that may be recognized from the option awards.

(3) In addition to the foregoing, on August 17, 2022, Mr. Seth was granted an award of 300,000 restricted stock units, or RSUs, which were granted in exchange for warrants that Mr. Seth received for services provided to the Company prior to becoming employed by Actinium. These warrants were granted on December 17, 2012 and vested and became exercisable on the 12-month anniversary of the grant date. The warrants were in the money for their entire existence since vesting. Mr. Seth was appointed Chairman of the Board in October 2013, became Executive Chairman in August 2014 and Chief Executive Officer in June 2017. Mr. Seth refrained from exercising the warrants in order to be aligned with the long-term interests of the Company and stockholders. In November 2018, the Board extended the expiration of Mr. Seth's warrants to February 2022. In February 2022, the Company requested that Mr. Seth not exercise the warrants to maintain alignment with the long-term interests of the Company. In exchange for refraining from exercising these warrants, the Board determined to grant Mr. Seth 300,000 RSUs based on the average fair value of the warrants during their vested life based on the Black-Scholes option-pricing model to continue to align Mr. Seth with the long-term interest of the Company and stockholders. The RSU grant was detailed on Form 4 filed with the SEC on August 19, 2022.

On December 28, 2023, Mr. Seth was granted an option to purchase 984,367 shares of common stock and Mr. O'Loughlin was granted an option to purchase 253,123 shares of common stock. The options have an exercise price of $5.00 per share and will expire on December 28, 2033. Pursuant to the terms of the Company's Amended and Restated 2019 Stock Plan, 2% of the options will vest each month from the date of grant.

The table below sets forth potential payments payable to our executive officers or former executive officers in the event of a termination of employment arrangement under various circumstances.

Pay versus PerfORMANCE

As required by Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation actually paid and certain financial performance of the Company. For the most recently completed fiscal year, the Company did not use any "financial performance measures" as defined in Item 402(v) of Regulation S-K to link compensation paid to our Named Executive Officers, or NEOs, to the Company's performance. We are also permitted to report as a "smaller reporting company" as defined under the U.S. federal securities laws. Accordingly, we have not included a tabular list of financial performance measures, and the table below does not include a column for a "Company-Selected Measure" as defined in Item 402(v) of Regulation S-K. For further information regarding our compensation philosophy and how we seek to align executive compensation with the Company's performance, refer to the section titled "Executive Compensation" above.

Refer to "Executive Compensation - Summary Compensation Table."

The dollar amounts do not reflect the actual amount of compensation earned by or paid to Mr. Seth during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the adjustments below were made to Mr. Seth's total compensation for each year to determine the compensation actually paid amount.

The dollar amounts do not reflect the actual amount of compensation earned by or paid to Mr. O'Loughlin during the applicable year.

The amounts deducted or added in calculating the equity award adjustments with regard to our PEO are as follows:

In addition to the foregoing, on August 17, 2022, Mr. Seth was granted an award of 300,000 restricted stock units, or RSUs, which were granted in exchange for warrants that Mr. Seth received for services provided to the Company prior to becoming employed by Actinium. These warrants were granted on December 17, 2012 and vested and became exercisable on the 12-month anniversary of the grant date. The warrants were in the money for their entire existence since vesting. Mr. Seth was appointed Chairman of the Board in October 2013, became Executive Chairman in August 2014 and Chief Executive Officer in June 2017. Mr. Seth refrained from exercising the warrants in order to be aligned with the long-term interests of the Company and stockholders. In November 2018, the Board extended the expiration of Mr. Seth's warrants to February 2022. In February 2022, the Company requested that Mr. Seth not exercise the warrants to maintain alignment with the long-term interests of the Company. In exchange for refraining from exercising these warrants, the Board determined to grant Mr. Seth 300,000 RSUs based on the average fair value of the warrants during their vested life based on the Black-Scholes option-pricing model to continue to align Mr. Seth with the long-term interest of the Company and stockholders. The RSU grant was detailed on Form 4 filed with the SEC on August 19, 2022. These RSUs are not included in the above table.

PROPOSAL 1

ELECTION OF DIRECTORS

Nominees for the Board of Directors

The Company's Charter established a classified Board with three classes of directors. Currently there are six directors divided into three classes designated Class I, Class II, and Class III. The term of office for each Class I director expires at the 2026 annual meeting of stockholders; the term of office for each Class II director expires at the Annual Meeting; and the term of office for each Class III director expires at the 2025 annual meeting of stockholders. Pursuant to the Charter, the directors due for election at the Annual Meeting are Jeffrey W. Chell and Sandesh Seth.

At the Annual Meeting, our stockholders will consider and vote upon the re-election of each of Jeffrey W. Chell and Sandesh Seth to serve as a Class II director for a term that continues pursuant to the director terms outlined below or until his successor is duly elected. In the event that a company nominee is unable or unwilling to serve as a director, the individual named as proxy on the proxy card will vote the shares that he represents for election of such other person or persons as the Board may recommend. The Board has no reason to believe that Jeffrey W. Chell and Sandesh Seth will be unable or unwilling to serve.

Following the Annual Meeting, the Board will consist of six directors. The term of each director is set forth below or until their successors are duly elected:

Directors elected at each annual meeting shall be elected for a 3-year term. There are no family relationships between any of the executive officers, directors and or persons nominated or chosen by the Company to become a director or executive officer.

Please see the biographies of Dr. Jeffrey W. Chell and Mr. Sandesh Seth in this proxy statement.

Vote Required

If a quorum is present, Dr. Chell and Mr. Seth will be elected by a plurality of the votes cast in person or by proxy at the Annual Meeting and entitled to vote on the election of directors. "Plurality" means that the nominees receiving the greatest number of affirmative votes will be elected as directors, up to the number of directors to be chosen at the meeting. If you hold your shares through a broker and you do not instruct the broker on how to vote with respect to the election of Dr. Chell or Mr. Seth, your broker will not have the authority to vote your shares. Withhold and broker non-votes will each be counted as present for purposes of determining the presence of a quorum but will not have any effect on the outcome of the vote.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" ELECTION OF
THE COMPANY NOMINEES DR. JEFFREY W. CHELL AND MR. SANDESH SETH

PROPOSAL 2

RATIFICATION OF THE APPOINTMENT OF MARCUM LLP

The Audit Committee has appointed Marcum as our independent registered public accounting firm to audit the consolidated financial statements of Actinium Pharmaceuticals, Inc. and its subsidiaries for the fiscal year ending December 31, 2024. Representatives of Marcum will not be present at the Annual Meeting but will have an opportunity to make a statement or to respond to appropriate questions from stockholders. Although stockholder ratification of the appointment of our independent auditor is not required by our Bylaws or otherwise, we are submitting the selection of Marcum to our stockholders for ratification to permit stockholders to participate in this important corporate decision. If not ratified, the Audit Committee will reconsider the selection, although the Audit Committee will not be required to select a different independent auditor for our Company.

Vote Required

If a quorum is present, the approval of the Auditor Ratification Proposal will require the affirmative vote of the holders of a majority in voting power of the shares present in person or by proxy and entitled to vote on the proposal at the Annual Meeting. An abstention is not an "affirmative vote," but an abstaining stockholder is considered "entitled to vote" at the Annual Meeting. Accordingly, an abstention will have the effect of a vote against the Auditor Ratification Proposal. Brokers are considered "entitled to vote" because brokers have discretionary voting authority on the Auditor Ratification Proposal. Because a broker non-vote is not an "affirmative vote," a broker non-vote will have the effect of a vote against the Auditor Ratification Proposal.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE AUDITOR RATIFICATION PROPOSAL

OTHER MATTERS

As of the date hereof, there are no other matters that we intend to present, or have reason to believe others will present, at the Annual Meeting. If, however, other matters properly come before the Annual Meeting, the accompanying proxy authorizes the person named as proxy or his substitute to vote on such matters as he determines appropriate.

HOUSEHOLDING OF PROXY MATERIALS

SEC rules concerning the delivery of annual disclosure documents allow us or your broker to send a single set of our proxy materials to any household at which two or more of our stockholders reside, if we or your broker believe that the stockholders are members of the same family. This practice, referred to as "householding," benefits both you and us. It reduces the volume of duplicate information received at your household and helps us to reduce our expenses. The rule applies to our annual reports, proxy statements and information statements. Once you receive notice from your broker or from us that communications to your address will be "householded," the practice will continue until you are otherwise notified or until you revoke your consent to the practice. Stockholders who participate in householding will continue to have access to and utilize separate proxy voting instructions.

If your household received a single set of proxy materials this year, but you would prefer to receive your own copy, please contact Alliance Advisors, by calling their toll-free number, 1-877-777-2857.

If you do not wish to participate in "householding" and would like to receive your own set of our annual disclosure documents in future years, follow the instructions described below. Conversely, if you share an address with another holder of our common stock and together both of you would like to receive only a single set of our annual disclosure documents, follow these instructions:

• If your shares are registered in your own name, please contact Alliance Advisors, and inform them of your request by calling them at 1-877-777-2857 or writing them at 200 Broadacres Drive, 3rd Fl., Bloomfield, NJ 07003

• If a broker, bank or other nominee holds your shares, please contact the broker, bank or other nominee directly and inform them of your request. Be sure to include your name, the name of your brokerage firm and your account number.

Electronic Delivery of Company Stockholder Communications

Most stockholders can elect to view future proxy statements and annual reports over the Internet instead of receiving paper copies in the mail.

You can choose this option and save the cost of producing and mailing these documents by:

• following the instructions provided when you submit a proxy to vote over the Internet; or

• going to www.AALvote.com/atnm and following the instructions provided.

SUBMISSION OF FUTURE STOCKHOLDER PROPOSALS

Pursuant to Rule 14a-8 under the Exchange Act ("Rule 14a-8"), a stockholder who intends to present a proposal at our next annual meeting of stockholders (the "2025 Annual Meeting") and who wishes the proposal to be included in the proxy statement and form of proxy for that meeting must submit the proposal in writing no later than July 8, 2025, or not less than 120 calendar days before the one-year anniversary date on which this proxy statement is released to stockholders (unless the date of the 2025 Annual Meeting is not scheduled to be held between October 28, 2025 and December 27, 2025, in which case the deadline will be a reasonable time before the company begins to print and send its proxy materials for the 2025 Annual Meeting), after which date such stockholder proposal will be considered untimely. Such proposal must be submitted on or before the close of business to our corporate offices at 100 Park Avenue, 23rd Floor, New York, New York 10017, Attn: Secretary.

Stockholders wishing to nominate a director or submit proposals to be presented directly at the 2025 Annual Meeting instead of by inclusion in next year's proxy statement must follow the submission criteria and deadlines set forth in our Bylaws concerning stockholder nominations and proposals. Stockholder nominations for director and other proposals that are not to be included in such materials must be received by our Secretary in writing at our corporate offices at 100 Park Avenue, 23rd Floor, New York, New York 10017, Attn: Secretary no later than July 30, 2025 and no earlier than June 30, 2025; provided, however, if and only if the 2025 Annual Meeting is not scheduled to be held between October 28, 2025 and February 5, 2026, to be timely, notice must be received not later than the later of the close of business on the one hundred twentieth (120th) day prior to the 2025 Annual Meeting and the tenth (10th) day following the day on which public announcement of the date of the 2025 Annual Meeting is first made by the Company, and not earlier than the close of business on the one hundred fiftieth (150th) day prior to the 2025 Annual Meeting. Any such stockholder proposals or nominations for director must also satisfy the requirements set forth in our Bylaws. To be eligible for inclusion in our proxy materials, stockholder proposals must also comply with the requirements of Rule 14a-8. Stockholders are also advised to review our Bylaws, which contain additional advance notice requirements, including requirements with respect to advance notice of stockholder proposals and director nominations. A proxy granted by a stockholder will give discretionary authority to the proxies to vote on any matters introduced pursuant to the above advance notice provisions in the Bylaws, subject to applicable rules of the SEC.

For the 2025 Annual Meeting, we will be required pursuant to Rule 14a-19 under the Exchange Act to include on our proxy card all nominees for director for whom we have received notice under the rule, which must be received no later than 60 calendar days prior to the anniversary of the Annual Meeting. For any such director nominee to be included on our proxy card for next year's annual meeting, notice must be received no later than September 28, 2025. Please note that the notice requirement under Rule 14a-19 is in addition to the applicable notice requirements under the advance notice provisions of our Bylaws described above.

A copy of our 2023 Annual Report is available to any person, including any beneficial owner of our shares, to whom this proxy statement is delivered upon oral or written request, without charge (except for exhibits, which are available upon payment of an appropriate processing fee).
