- Actinium Pharmaceuticals, Inc. (the &#x201c;Company&#x201d; or &#x201c;Actinium&#x201d;) is a pioneer in the development of targeted radiotherapies
intended to meaningfully improve outcomes for patients with advanced cancers including relapsed or refractory disease who have failed
existing therapies. It is advancing a pipeline of differentiated clinical stage product candidates focused on validated cancer targets.
Its current pipeline is focused on indications in myeloid malignancies, solid tumors and conditioning for cell and gene therapies that
the Company believes have high unmet needs that are not addressed by currently available treatment options.&lt;/p&gt;

a fair statement of the results for the interim periods presented. Interim results are not necessarily indicative of the results for the
full year. These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated
financial statements and notes thereto contained in the Company&#x2019;s Annual Report on Form 10-K for the year ended December 31, 2024.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;b&gt;Principles of Consolidation
-&lt;/b&gt; The basis of consolidation is unchanged from the disclosure in the Company&#x2019;s Notes to the Consolidated Financial Statements
section in its Annual Report on Form 10-K for the year ended December 31, 2024. The unaudited condensed consolidated financial statements
include the Company&#x2019;s accounts and those of the Company&#x2019;s wholly owned subsidiaries.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;b&gt;Use of Estimates &lt;/b&gt;-
The preparation of these unaudited interim condensed consolidated financial statements in conformity with U.S. GAAP requires management
to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the unaudited interim condensed
consolidated financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those
estimates.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;b&gt;Segment Information - &lt;/b&gt;The
Company operates as a single operating and reportable segment for the purposes of assessing performance and allocating resources. The
Company&#x2019;s chief operating decision maker is its Chief Executive Officer, who reviews total assets in the consolidated balance sheets
and net loss and its components in the consolidated statements of operations; research and development expenses, general and administrative
expenses, and interest income, for the purposes of making operating decisions, assessing financial performance, and allocating resources.
All assets are in the United States.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;b&gt;Cash, Cash Equivalents
and Restricted Cash -&lt;/b&gt; The Company considers all highly liquid accounts with original maturities of three months or less to be cash
equivalents. The Company holds most of its cash equivalents in a money market account comprised of US Treasury notes. Balances held by
the Company are typically in excess of Federal Deposit Insurance Corporation insured limits.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;The following is a summary
of cash, cash equivalents and restricted cash at March 31, 2025 and December 31, 2024:&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;b&gt;Leases &lt;/b&gt;&#x2013; The
Company has an operating lease for corporate office space and a finance lease for office equipment located at the corporate office space.
Leases with an initial term of 12 months or less are not recorded on the balance sheet; lease expense for these leases is recognized on
a straight-line basis over the lease term.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;b&gt;Fair Value Measurement
- &lt;/b&gt;Fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction
between market participants. A fair value hierarchy has been established for valuation inputs that gives the highest priority to quoted
prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 27.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;b&gt;Revenue Recognition &lt;/b&gt;-
The Company recognizes revenue in accordance with Accounting Standards Codification (ASC) Topic 606, &lt;i&gt;Revenue From Contracts With
Customers &lt;/i&gt;(&#x201c;ASC 606"). Under ASC 606, an entity recognizes revenue when its customer obtains control of promised
goods or services, in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or
services. To determine revenue recognition for arrangements within the scope of ASC 606, the entity performs the following five
steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the
transaction price, including variable consideration, if any; (iv) allocate the transaction price to the performance obligations in
the contract; and (v) recognize revenue as the entity satisfies a performance obligation. The Company only applies the five-step
model to contracts when it is probable that the entity will collect the consideration to which it is entitled in exchange for the
goods or services it transfers to the customer. There was no revenue for the three months ended March 31, 2025 and March 31, 2024, respectively.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 24.5pt; background-color: white"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;At contract inception, once
the contract is determined to be within the scope of ASC 606, the Company assesses whether the promised goods or services promised within
each contract are distinct and, therefore, represent a separate performance obligation.&#160;Goods and services that are determined not
to be distinct are combined with other promised goods and services until a distinct bundle is identified. In determining whether goods
or services are distinct, the Company evaluates certain criteria, including whether (i)&#160;the customer can benefit from the good or
service either on its own or together with other resources that are readily available to the customer (capable of being distinct) and
(ii)&#160;the good or service is separately identifiable from other goods or services in the contract (distinct in the context of the
contract).&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24.5pt; background-color: white"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;The Company then determines
the transaction price, which is the amount of consideration it expects to be entitled from a customer in exchange for the promised goods
or services for each performance obligation and recognizes the associated revenue as each performance obligation is satisfied. The Company&#x2019;s
estimate of the transaction price for each contract includes all variable consideration to which it expects to be entitled. Variable consideration
includes payments in the form of collaboration milestone payments. If an arrangement includes collaboration milestone payments, the Company
evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price
using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value
is included in the transaction price.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24.5pt; background-color: white"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;ASC 606 requires the Company
to allocate the arrangement consideration on a relative standalone selling price basis for each performance obligation after determining
the transaction price of the contract and identifying the performance obligations to which that amount should be allocated. The relative
standalone selling price is defined in the revenue standard as the price at which an entity would sell a promised good or service separately
to a customer. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance
obligation as each performance obligation is satisfied, either at a point in time or over time, and if over time, recognition is based
on the use of an output or input method.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;b&gt;Collaborative Arrangements
&lt;/b&gt;- The Company follows the accounting guidance for collaboration agreements with third parties, which requires that certain transactions
between the Company and collaborators be recorded in its consolidated statements of operations on either a gross basis or net basis,
depending on the characteristics of the collaborative relationship, and requires enhanced disclosure of collaborative relationships.
The Company evaluates its collaboration agreements for proper classification in its consolidated statements of operations based on the
nature of the underlying activity. When the Company has concluded that it has a customer relationship with one of its collaborators,
the Company follows the guidance of ASC 606&lt;i&gt;. &lt;/i&gt;There was no revenue for the three months ended March 31, 2025 and March 31, 2024,
respectively.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;b&gt;Grant Revenue&lt;/b&gt; &lt;i&gt;&#x2013;
&lt;/i&gt;The Company has a grant from a government-sponsored entity for research and development related activities that provides for payments
for reimbursed costs, which included overhead and general and administrative costs as well as an administrative fee. The Company recognizes
revenue from grants as it performed services under this arrangement. Associated expenses are recognized when incurred as research and
development expense. Revenue and related expenses are presented gross in the consolidated statements of operations.&lt;b&gt;&#160;&lt;/b&gt;There
was no grant revenue for the three months ended March 31, 2025 and March 31, 2024, respectively.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;b&gt;License Revenue &lt;i&gt;&#x2013;
&lt;/i&gt;&lt;/b&gt;The Company entered into a product licensing agreement whereby the Company allowed a third party to commercialize a certain product
in specified territories using the Company&#x2019;s trademarks. The terms of this arrangement includes payment to the Company for a combination
of one or more of the following: upfront license fees; development, regulatory and sales-based milestone payments; and royalties on net
sales of licensed products. The Company uses its judgment to determine whether milestones or other variable consideration should be included
in the transaction price.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;i&gt;Upfront license fees&lt;/i&gt;:
If the license to the Company&#x2019;s intellectual property is determined to be distinct from the other performance obligations identified
in the arrangement, the Company will recognize revenue from upfront license fees allocated to the license when the license is transferred
to the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other promises, the Company
determines whether the combined performance obligation is satisfied over time or at a point in time.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;i&gt;Development, regulatory
or commercial milestone payments&lt;/i&gt;: At the inception of each arrangement that includes payments based on the achievement of certain
development, regulatory and sales-based or commercial events, the Company evaluates whether the milestones are considered probable of
being achieved and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable
that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments
that are not within the Company&#x2019;s or the licensee&#x2019;s control, such as regulatory approvals, are not considered probable of
being achieved until regulatory approval is received. At the end of each subsequent reporting period, the Company will re-evaluate the
probability of achieving such development and regulatory milestones and any related constraint, and if necessary, adjust the Company&#x2019;s
estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis and recorded as part of license
revenue during the period of adjustment.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;i&gt;Sales-based milestone payments
and royalties&lt;/i&gt;: For arrangements that include sales-based royalties, including milestone payments based on the volume of sales, the
Company will determine whether the license is deemed to be the predominant item to which the royalties or sales-based milestones relate
and if such is the case, the Company will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance
obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied).&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;Upfront payments and fees
may require deferral of revenue recognition to a future period until the Company performs its obligations under these arrangements or
when it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur or when the uncertainty
associated with any variable consideration is subsequently resolved. Amounts payable to the Company are recorded as accounts receivable
when the Company&#x2019;s right to consideration is unconditional. There was no revenue for the three months ended March 31, 2025 and March 31, 2024, respectively.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;b&gt;Research and Development
Costs -&lt;/b&gt; Research and development costs are expensed as incurred. These costs include the costs of manufacturing drug product, the
costs of clinical trials, costs of employees and associated overhead, and depreciation and amortization costs related to facilities and
equipment. Research and development reimbursements are recorded by the Company as a reduction of research and development costs.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;b&gt;&#160;&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;b&gt;Share-Based Payments -
&lt;/b&gt;The Company estimates the fair value of each stock option award at the grant date by using the Black-Scholes option pricing model.
The fair value determined represents the cost for the award and is recognized over the vesting period during which an employee is required
to provide service in exchange for the award. The Company accounts for forfeitures of stock options as they occur.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;b&gt;Net Loss Per Common Share
&lt;/b&gt;- Basic loss per common share is computed by dividing the net loss available to common stockholders by the weighted average number
of shares of common stock outstanding during the reporting period. For periods of net loss, diluted loss per share is calculated similarly
to basic loss per share because the impact of all potential dilutive common shares is anti-dilutive. For the three months ended March
31, 2025 and 2024, the Company&#x2019;s potentially dilutive shares, which include outstanding common stock options, restricted stock units
and warrants, have not been included in the computation of diluted net loss per share as the result would have been anti-dilutive.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;In November 2023, FASB issued
ASU 2023-07, &lt;i&gt;Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures&lt;/i&gt;, which provides improvements to reportable
segment disclosure requirements, primarily through enhanced disclosures around segment expenses. ASU 2023-07 requires the Company to disclose
significant segment expenses that are regularly provided to the chief operating decision maker, or CODM, and included within each reported
measure of segment profit or loss. ASU 2023-07 also requires that the Company disclose an amount for other segment items by reportable
segment, a description of their composition and provide all annual disclosures about a reportable segment&#x2019;s profit or loss and assets
pursuant to Topic 280 during interim periods. The Company must also disclose the CODM&#x2019;s title and position, as well as certain information
around the measures used by the CODM and an explanation of how the CODM uses the reported measures in assessing segment performance and
deciding how to allocate resources. For public entities with a single reportable segment, the entity must provide all the disclosures
required pursuant to ASU 2023-07 and all existing segment disclosures under Topic 280. The Company adopted this standard effective January
1, 2024, and reported in its Annual Report on Form 10-K for the year ended
December 31, 2024.&lt;/p&gt;

issued ASU 2024-03,&#160;&lt;i&gt;Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures&lt;/i&gt;&#160;(Subtopic
220-40), to improve the disaggregation of expenses within the consolidated statement of operations. The amendments in ASU 2024-03
require disclosures in the notes to the consolidated financial statements and specified information about certain costs and
expenses. The amendments require that at each interim and annual reporting period an entity disclose (a) employee compensation, (b)
depreciation, and (c) intangible asset amortization included in each relevant expense caption; include certain amounts that are
already required to be disclosed under current GAAP in the same disclosure as the other disaggregation requirements; and disclose a
qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively.
The amendments in ASU 2024-03 are effective January 1, 2027 and effective for interim periods beginning January 1, 2028. The Company
is currently evaluating the impact of ASU 2024-03 on its financial statements.&lt;/p&gt;

ASU 2023-09, &lt;i&gt;Income Taxes (Topic 740): Improvements to Income Tax Disclosures&lt;/i&gt;, to enhance the transparency and decision usefulness
of income tax disclosures. The amendments in ASU 2023-09 provide improvements primarily related to the rate reconciliation and income
taxes paid information included in income tax disclosures. The Company is required to disclose additional information regarding reconciling
items equal to or greater than five percent of the amount computed by multiplying pretax income (loss) by the applicable statutory tax
rate. Similarly, the Company is required to disclose income taxes paid (net of refunds received) equal to or greater than five percent
of total income taxes paid (net of refunds received). &lt;span style="background-color: white"&gt;The amendments in ASU 2023-09 are effective

- &lt;/b&gt;Fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction

The Company recognizes revenue in accordance with Accounting Standards Codification (ASC) Topic 606, &lt;i&gt;Revenue From Contracts With
Customers &lt;/i&gt;(&#x201c;ASC 606"). Under ASC 606, an entity recognizes revenue when its customer obtains control of promised
goods or services, in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or
services. To determine revenue recognition for arrangements within the scope of ASC 606, the entity performs the following five
steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the
transaction price, including variable consideration, if any; (iv) allocate the transaction price to the performance obligations in
the contract; and (v) recognize revenue as the entity satisfies a performance obligation. The Company only applies the five-step
model to contracts when it is probable that the entity will collect the consideration to which it is entitled in exchange for the
goods or services it transfers to the customer. There was no revenue for the three months ended March 31, 2025 and March 31, 2024, respectively.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;At contract inception, once
the contract is determined to be within the scope of ASC 606, the Company assesses whether the promised goods or services promised within
each contract are distinct and, therefore, represent a separate performance obligation.&#160;Goods and services that are determined not
to be distinct are combined with other promised goods and services until a distinct bundle is identified. In determining whether goods
or services are distinct, the Company evaluates certain criteria, including whether (i)&#160;the customer can benefit from the good or
service either on its own or together with other resources that are readily available to the customer (capable of being distinct) and
(ii)&#160;the good or service is separately identifiable from other goods or services in the contract (distinct in the context of the
contract).&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;The Company then determines
the transaction price, which is the amount of consideration it expects to be entitled from a customer in exchange for the promised goods
or services for each performance obligation and recognizes the associated revenue as each performance obligation is satisfied. The Company&#x2019;s
estimate of the transaction price for each contract includes all variable consideration to which it expects to be entitled. Variable consideration
includes payments in the form of collaboration milestone payments. If an arrangement includes collaboration milestone payments, the Company
evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price
using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value
is included in the transaction price.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;ASC 606 requires the Company
to allocate the arrangement consideration on a relative standalone selling price basis for each performance obligation after determining
the transaction price of the contract and identifying the performance obligations to which that amount should be allocated. The relative
standalone selling price is defined in the revenue standard as the price at which an entity would sell a promised good or service separately
to a customer. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance
obligation as each performance obligation is satisfied, either at a point in time or over time, and if over time, recognition is based
on the use of an output or input method.&lt;/p&gt;</us-gaap:RevenueFromContractWithCustomerPolicyTextBlock>

&lt;/b&gt;- The Company follows the accounting guidance for collaboration agreements with third parties, which requires that certain transactions
between the Company and collaborators be recorded in its consolidated statements of operations on either a gross basis or net basis,
depending on the characteristics of the collaborative relationship, and requires enhanced disclosure of collaborative relationships.
The Company evaluates its collaboration agreements for proper classification in its consolidated statements of operations based on the
nature of the underlying activity. When the Company has concluded that it has a customer relationship with one of its collaborators,
the Company follows the guidance of ASC 606&lt;i&gt;. &lt;/i&gt;There was no revenue for the three months ended March 31, 2025 and March 31, 2024,
respectively.&lt;/p&gt;</us-gaap:CollaborativeArrangementAccountingPolicy>

&lt;/i&gt;The Company has a grant from a government-sponsored entity for research and development related activities that provides for payments
for reimbursed costs, which included overhead and general and administrative costs as well as an administrative fee. The Company recognizes
revenue from grants as it performed services under this arrangement. Associated expenses are recognized when incurred as research and
development expense. Revenue and related expenses are presented gross in the consolidated statements of operations.&lt;b&gt;&#160;&lt;/b&gt;There
was no grant revenue for the three months ended March 31, 2025 and March 31, 2024, respectively.&lt;/p&gt;</us-gaap:GovernmentAssistancePolicyTextBlock>

&lt;/i&gt;&lt;/b&gt;The Company entered into a product licensing agreement whereby the Company allowed a third party to commercialize a certain product
in specified territories using the Company&#x2019;s trademarks. The terms of this arrangement includes payment to the Company for a combination
of one or more of the following: upfront license fees; development, regulatory and sales-based milestone payments; and royalties on net
sales of licensed products. The Company uses its judgment to determine whether milestones or other variable consideration should be included
in the transaction price.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;i&gt;Upfront license fees&lt;/i&gt;:
If the license to the Company&#x2019;s intellectual property is determined to be distinct from the other performance obligations identified
in the arrangement, the Company will recognize revenue from upfront license fees allocated to the license when the license is transferred
to the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other promises, the Company
determines whether the combined performance obligation is satisfied over time or at a point in time.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;i&gt;Development, regulatory
or commercial milestone payments&lt;/i&gt;: At the inception of each arrangement that includes payments based on the achievement of certain
development, regulatory and sales-based or commercial events, the Company evaluates whether the milestones are considered probable of
being achieved and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable
that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments
that are not within the Company&#x2019;s or the licensee&#x2019;s control, such as regulatory approvals, are not considered probable of
being achieved until regulatory approval is received. At the end of each subsequent reporting period, the Company will re-evaluate the
probability of achieving such development and regulatory milestones and any related constraint, and if necessary, adjust the Company&#x2019;s
estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis and recorded as part of license
revenue during the period of adjustment.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&lt;i&gt;Sales-based milestone payments
and royalties&lt;/i&gt;: For arrangements that include sales-based royalties, including milestone payments based on the volume of sales, the
Company will determine whether the license is deemed to be the predominant item to which the royalties or sales-based milestones relate
and if such is the case, the Company will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance
obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied).&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;Upfront payments and fees
may require deferral of revenue recognition to a future period until the Company performs its obligations under these arrangements or
when it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur or when the uncertainty
associated with any variable consideration is subsequently resolved. Amounts payable to the Company are recorded as accounts receivable
when the Company&#x2019;s right to consideration is unconditional. There was no revenue for the three months ended March 31, 2025 and March 31, 2024, respectively.&lt;/p&gt;</atnm:LicenseRevenuePolicyTextBlock>

of shares of common stock outstanding during the reporting period. For periods of net loss, diluted loss per share is calculated similarly
to basic loss per share because the impact of all potential dilutive common shares is anti-dilutive. For the three months ended March

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 27.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;On June 15, 2012, the Company
entered into a license and sponsored research agreement with Fred Hutchinson Cancer Research Center (&#x201c;FHCRC&#x201d;) to build upon
previous and ongoing clinical trials with apamistamab (licensed antibody). FHCRC has completed both a Phase 1 and Phase 2 clinical trial
with apamistamab. The Company has been granted exclusive rights to the antibody and related master cell bank developed by FHCRC. A milestone
payment of $1 million will be due to FHCRC upon U.S. Food and Drug Administration (&#x201c;FDA&#x201d;) approval of the first drug utilizing
the licensed antibody. Upon commercial sale of the drug, royalty payments of 2% of net sales will be due to FHCRC.&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in; background-color: white"&gt;On

No. 1:25-cv-02553 in the Southern District of New York, wherein, the Securities Complaint alleges that the Defendants made material misrepresentations
and omissions concerning the Iomab-B Phase 3 Sierra Trial and the plaintiff asserts claims against all Defendants pursuant to section
10(b) of the Securities Exchange Act (the &#x201c;Exchange Act&#x201d;) and Rule 10b-5 promulgated thereunder, as well as additional claims
against the individual Defendants pursuant to Section 20(a) of the Exchange Act.&#160; The Complaint purports to assert class action claims
on behalf of all persons and entities that purchased or otherwise acquired Actinium securities between October 31, 2022 and August 2,
2024.&#160; Plaintiff seeks unspecified damages.&#160; On May 5, 2025, a derivative shareholder complaint (the &#x201c;Derivative Complaint&#x201d;)
was filed against the Company and certain of the Company&#x2019;s directors and officers alleging derivative liability for the allegations
made in the Securities Complaint.&#160; The Defendants have not yet responded to the Securities Complaint, and they intend to vigorously
defend themselves against the plaintiff&#x2019;s allegations.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 27.5pt"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;The Company determines if
an arrangement is a lease at inception. This determination generally depends on whether the arrangement conveys to the Company the right
to control the use of a fixed asset for a period of time in exchange for consideration. Control of an underlying asset is conveyed to
the Company if the Company obtains the rights to direct the use of and to obtain substantially all of the economic benefits from using
the underlying asset. The Company has lease agreements which include lease and non-lease components, which the Company has elected to
account for as a single lease component for all classes of underlying assets. Lease expense for variable lease components are recognized
when the obligation is probable. The Company made an accounting policy election to exclude from balance sheet reporting those leases with
initial terms of 12 months or less.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;Right-of-use assets and liabilities
are recognized at commencement date based on the present value of lease payments over the lease term. ASC 842 requires a lessee to discount
its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental
borrowing rate. As an implicit interest rate was not readily determinable in the Company&#x2019;s leases, the incremental borrowing rate
was used based on the information available at commencement date in determining the present value of lease payments.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;The lease term for all of
the Company&#x2019;s leases includes the non-cancellable period of the lease plus any additional periods covered by either a Company option
to extend (or not to terminate) the lease that the Company is reasonably certain to exercise, or an option to extend (or not to terminate)
the lease controlled by the lessor. Options for lease renewals have been excluded from the lease term (and lease liability) for the majority
of the Company&#x2019;s leases as the reasonably certain threshold is not met.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;At March 31, 2025, the Company
has two leases which have been capitalized in accordance with ASC 842, one for corporate office space and one for office equipment. The
Company entered into a lease for corporate office space effective June 1, 2022. The lease has a term of 5 years 2 months, with an expiration
date of July 30, 2027 and current annual rent of $0.6 million. The Company is also responsible for certain other costs, such as insurance,
utilities and maintenance.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;As the interest rate implicit
in the leases was not readily determinable at the time that the leases were evaluated, the Company used its incremental borrowing rate
based on the information available in determining the present value of lease payments. The Company&#x2019;s incremental borrowing rate
was based on the term of the lease, the economic environment of the lease and reflects the rate the Company would have had to pay to borrow
on a secured basis. Below is information on the weighted average discount rates used at the time that the leases were evaluated:&lt;/p&gt;

to which Immedica licensed the exclusive product rights for commercialization of Iomab-B (I-131 apamistamab) in the European Economic
Area, Middle East and North Africa (&#x201c;EUMENA&#x201d;), including Algeria, Andorra, Bahrain, Cyprus, Egypt, Iran, Iraq, Israel, Jordan,
Kuwait, Lebanon, Libya, Monaco, Morocco, Oman, Palestine, Qatar, San Marino, Saudi Arabia, Switzerland, Syria, Tunisia, Turkey, the United

of $35 million from Immedica, which was received in May 2022. Under the terms of the License Agreement, the Company is eligible to receive
certain regulatory and commercial milestone payments and royalties on net sales of the product in certain countries that may result from
the License Agreement. The Company continues to retain commercialization rights in the U.S. and rest of the world.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;The Company&#x2019;s contract

unaudited condensed consolidated balance sheets, depending on the short-term or long-term nature of the payments to be recognized. The
Company&#x2019;s contract liabilities primarily consist of advanced payments from licensees. Long-term license revenue deferred was $35
million at March 31, 2025 and December 31, 2024; this deferred revenue will be recognized upon European Union&#x2019;s regulatory approval
of Iomab-B or provision of definitive feedback that Iomab-B will not receive approval in the European Union.&lt;/p&gt;</atnm:OtherRevenueTextBlock>

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;During the three months ended
March 31, 2025, the Company granted new employees options to purchase 25 thousand shares of
common stock with an exercise price ranging from $1.06 to $1.43 per share, a term of 10 years, and a vesting period of 4 years. The options
had an aggregated fair value of $28 thousand that was calculated using the Black-Scholes option-pricing model. Variables used in the Black-Scholes
option-pricing model include: (1) discount rate range from 4.0% to 4.5% (2) expected life of 6 years, (3) expected volatility range from
90.6% to 90.7%, and (4) &lt;span style="-sec-ix-hidden: hidden-fact-51"&gt;zero&lt;/span&gt; expected dividends. During the three months ended March 31, 2024, the Company did not grant any stock options.&lt;/p&gt;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;On March 31, 2025, the Board of Directors approved of the cancellation
of stock options to purchase an aggregate of 4.9 million shares of common stock held by certain current employees and directors that were
initially granted under the Amended and Restated 2013 Stock Plan and the 2019 Amended and Restated Stock Plan. Such cancellations were
subject to the consent of the applicable holders of the stock options, which the Company received. The cancellation of these stock options
resulted in the recording of $8.7 million in stock compensation expense. During the three months ended March 31, 2024, the Company recorded
compensation expense related to stock options of $1.2 million.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;The fair values of all options
issued and outstanding are being amortized over their respective vesting periods. The unrecognized compensation expense at March 31, 2025
was $0.4 million related to unvested options, which is expected to be expensed over a weighted average of 2.3 years.&lt;/p&gt;
