INTERNATIONAL ISOTOPES INC. AND SUBSIDIARIES

Notes to Unaudited Condensed Consolidated Financial Statements

September 30, 2021

(1) The Company and Basis of Presentation

International Isotopes Inc. (INIS) was incorporated in Texas in November 1995. The accompanying unaudited condensed consolidated financial statements are presented in conformity with accounting principles generally accepted in the United States of America (GAAP) and include all operations and balances of INIS and its wholly owned subsidiaries, including RadQual, LLC (RadQual). The unaudited condensed consolidated financial statements also include the accounts of INIS’s 50% owned joint venture, TI Services, LLC (TI Services). TI Services is headquartered in Youngstown, Ohio and was formed with RadQual in December 2010 to distribute products and services for nuclear medicine, nuclear cardiology and Positron Emission Tomography (PET) imaging. RadQual is a global supplier of molecular imaging quality control and calibration devices, and is headquartered in Idaho Falls, Idaho. In August 2017, affiliates of INIS purchased 75.5% of RadQual and at the time INIS was named as one of the two managing members of RadQual. In July 2021, INIS purchased the remaining interest in RadQual and now owns 100% of RadQual. INIS, its subsidiaries (including RadQual) and TI Services are collectively referred to herein as the “Company,” “we,” “our” or “us.”

Affiliates

Nature of Operations – INIS and its subsidiaries (including RadQual) and TI Services manufacture a full range of nuclear medicine calibration and reference standards, generic sodium iodide I-131 drug product, cobalt teletherapy sources, and a varied selection of radiochemicals for medical research, and clinical applications. The Company’s business consists of five business segments: Nuclear Medicine Standards, Cobalt Products, Radiochemical Products, Fluorine Products, and Radiological Services. The Company’s headquarters and all operations, with the exception of TI Services, are located in Idaho Falls, Idaho.

With the exception of certain unique products, the Company’s normal operating cycle is considered to be one year. Due to the time required to produce some cobalt products, the Company’s operating cycle for those products is considered to be two to three years. Accordingly, preliminary payments received on cobalt contracts, where shipment will not take place for greater than one year, have been recorded as unearned revenue and, depending upon estimated ship dates, classified under either current or long-term liabilities on the Company’s condensed consolidated balance sheets. These unearned revenues are being recognized as revenue in the periods during which the cobalt shipments take place. All assets expected to be realized in cash or sold during the normal operating cycle of business are classified as current assets.

Principles of Consolidation

Principles of Consolidation – The accompanying unaudited condensed consolidated financial statements are presented in conformity with GAAP and include all operations and balances of INIS and its wholly-owned subsidiaries. See Note 4 “RadQual Acquisition” for additional information regarding RadQual. All significant intercompany accounts and transactions have been eliminated in consolidation.

Interim Financial Information

Interim Financial Information – The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (SEC). Accordingly, the accompanying unaudited condensed consolidated financial statements do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments and reclassifications considered necessary in order to make the financial statements not misleading and for a fair and comparable presentation have been included and are of a normal recurring nature. Operating results for the three or nine-month period ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021 or any future periods. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC on March 30, 2021.

Recent Accounting Pronouncements

Recent Accounting Pronouncements – In August 2020, the Financial Accounting Standards Board issued ASU 2020-06 Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40). The update simplifies accounting related to convertible debt instruments. The standard is effective for fiscal years beginning after December 15, 2023 including interim periods within those fiscal years. INIS is currently evaluating the effect this standard will have on its financial statements.

(2) Current Developments and Liquidity

Business Condition – Since inception, the Company has incurred substantial losses. During the nine months ended September 30, 2021, the Company reported net loss of $919,408, net of non-controlling interest, and net cash provided by operating activities of $64,294. During the nine months ended September 30, 2020, the Company reported net income of $113,884, net of non-controlling interest, and net cash provided by operating activities of $960,314.

During the nine months ended September 30, 2021, the Company continued its focus on its strongest long-standing core business segments which consist of its radiochemical products, cobalt products, and nuclear medicine standards, and in particular, the pursuit of new business opportunities within those segments.

Additionally, the Company holds a Nuclear Regulatory Commission (NRC) construction and operating license for the depleted uranium facility in, as well as the property agreement with, Lea County, New Mexico, where the plant is intended to be constructed. The NRC license for the de-conversion facility is a forty (40) year operating license and is the first commercial license of this type issued in the United States. There are no other companies with a similar license application under review by the NRC. Therefore, the NRC license represents a significant competitive barrier, and the Company considers it a valuable asset.

The Company expects that cash from operations, equity or debt financing, and its current cash balance will be sufficient to fund operations for the next twelve months. Future liquidity and capital funding requirements will depend on numerous factors, including, contract manufacturing agreements, commercial relationships, technological developments, market factors, available credit, and voluntary warrant redemption by shareholders. There is no assurance that additional capital and financing will be available on acceptable terms to the Company or at all.

(3) Net Income (Loss) Per Common Share - Basic and Diluted

For the three and nine months ended September 30, 2021, the Company had 21,102,500 stock options outstanding, 7,065,000 warrants outstanding, 675 outstanding shares of Series B redeemable convertible preferred stock (Series B Preferred Stock), and 4,063 outstanding shares of Series C redeemable convertible preferred stock (Series C Preferred Stock), each of which were not included in the computation of diluted income (loss) per common share because they would be anti-dilutive.

For the nine months ended September 30, 2020, the Company had 13,875,000 stock options outstanding, 20,090,000 warrants outstanding, 4,213 outstanding shares of Series C Preferred Stock, and 850 outstanding shares of Series B Preferred Stock, each of which were not included in the computation of diluted income (loss) per common share because they would be anti-dilutive. The Company used the treasury stock method in calculating weighted average common shares diluted.

For the three months ended September 30, 2020, the Company had 13,875,000 stock options outstanding, 20,090,000 warrants outstanding, 4,213 outstanding shares of Series C redeemable convertible preferred stock, and 850 outstanding shares of Series B redeemable convertible preferred stock, each of which were not included in the computation of diluted income (loss) per common share because they would be anti-dilutive.

(4) RadQual Acquisition

On July 8, 2021, the Company entered into a Membership Interest Purchase Agreement (the Purchase Agreement) with RadQual and the sellers set forth in the Purchase Agreement, which included the Company’s Chairman of the Board, Chief Executive Officer, former Chairman of the Board, and certain other stockholders of the Company (collectively, the “Sellers”). Pursuant to the Purchase Agreement, the Company acquired all of the outstanding membership interests of RadQual not then owned by the Company for an aggregate purchase price of approximately $4.4 million, payable in shares of the Company’s common stock valued at $0.11 per share (determined by the average trading price of the Company’s common stock on the OTC Markets during the 60 trading day period immediately prior to June 2, 2021) (the “RadQual Acquisition”). The Company issued an aggregate of 40,176,236 shares of its common stock to the Sellers as consideration in the RadQual Acquisition. Prior to the RadQual Acquisition, the Company owned approximately 24.5% of the outstanding membership interests of RadQual, and after acquiring all of the remaining membership interests of RadQual, RadQual became a wholly-owned subsidiary of the Company. The RadQual Acquisition closed on July 8, 2021.

(5) Inventories

Inventories consisted of the following at September 30, 2021 and December 31, 2020:

	September 30, 2021		December 31, 2020
Raw materials	$	33,609	$	33,609
Work in process		548,689		803,171
Finished goods		—		1,007
Total inventory	$	582,298	$	837,787

Work in process also includes costs to irradiate cobalt-60 material under a contract with the DOE. This material has been placed in the ATR and the Company made progress payments to purchase this material. During the second quarter and fourth quarter of 2020, the Company modified its agreement with the DOE due to delays in delivery of Cobalt material. As a result, the DOE refunded certain payments made by INIS in relation to this material and INIS stopped paying the scheduled payments for the inventory. At September 30, 2021, and at December 31, 2020, this cobalt target inventory had a carrying value of $0 and $383,312, respectively.

The Company has contracted with several customers for the sale of some of this cobalt material and has collected advance payments for project management, up-front handling, and other production costs from those customers. The advance payments from customers were recorded as unearned revenue which are recognized in the Company’s condensed consolidated financial statements as cobalt products are completed and shipped. For the nine months ended September 30, 2021, and 2020, the Company recognized approximately $160,000 and $145,500, respectively, of revenue in its condensed consolidated statements of operations for customer orders filled during the period under these cobalt contracts. For the three-months ended September 30, 2021, and 2020, the Company recognized approximately $1,500 and $123,500, respectively of revenue in its condensed consolidated statements of operations for customer orders filled during the period under these cobalt contracts.

(6) Stockholders’ Equity, Options, and Warrants

Employee Stock Purchase Plan

The Company has an employee stock purchase plan pursuant to which employees of the Company may participate to purchase shares of common stock at a discount. During the nine months ended September 30, 2021, and 2020, the Company issued 256,079 and 303,610 shares of common stock, respectively, to employees under the employee stock purchase plan for proceeds of $13,528 and $13,430, respectively. As of September 30, 2021, 2,843,832 shares of common stock remain available for issuance under the employee stock purchase plan.

Stock-Based Compensation Plans

2015 Incentive Plan - In April 2015, the Company’s Board of Directors approved the International Isotopes Inc. 2015 Incentive Plan (as amended, the 2015 Plan), which was subsequently approved by the Company’s shareholders in July 2015. The 2015 Plan was amended and restated in July 2018 to increase the number of shares authorized for issuance under the 2015 Plan by an additional 20,000,000 shares. The 2015 Plan provides for the grant of incentive and non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares and units, and other stock or cash-based awards. At September 30, 2021, there were 34,244,913 shares available for issuance under the 2015 Plan.

Employee/Director Grants - The Company accounts for issuances of stock-based compensation to employees by recognizing, as compensation expense, the cost of employee services received in exchange for equity awards. The compensation expense is based on the grant date fair value of the award. Stock option compensation expense is recognized over the period during which an employee is required to provide service in exchange for the award (the vesting period).

Non-Employee Grants - The Company accounts for its issuances of stock-based compensation to non-employees by recognizing compensation expense based on the grant date fair value of the award. Stock option compensation expense is recognized over the vesting period for the award.

Option awards outstanding as of September 30, 2021, and changes during the nine months ended September 30, 2021, were as follows:

Fixed Options	Shares			Weighted Average Exercise Price		Weighted Average Remaining Contractual Life		Aggregate Intrinsic Value
Outstanding at December 31, 2020		20,400,000		$	0.06
Granted		3,225,000			0.11
Exercised		(2,262,500	)		0.04
Expired		—			—
Forfeited		(260,000	)		0.07
Outstanding at September 30, 2021		21,102,500			0.06		5.7	$	998,475
Exercisable at September 30, 2021		15,790,500		$	0.05		4.6	$	882,095

The intrinsic value of outstanding and exercisable shares is based on the closing price of the Company’s common stock on the OTCQB of $0.11 per share on September 30, 2021, the last trading day of the quarter.

As of September 30, 2021, there was $157,582 of unrecognized compensation expense related to stock options that will be recognized over a weighted-average period of 2.60 years.

Total stock-based compensation expense for the nine months ended September 30, 2021, and 2020 was $60,671 and $80,203 respectively. Total stock-based compensation expense for the three-months ended September 30, 2021, and 2020 was $11,578 and $11,672, respectively.

During the nine months ended September 30, 2021, the Company granted an aggregate of 3,225,000 qualified stock options to several of its employees. All options vest over a five-year period with the first vesting at the one-year anniversary for all grants and expiration at ten-year anniversary for all grants. The weighted average exercise price for these options was $0.11 per share. The options have a fair value of $208,166 as estimated on the date of issue using the Black-Scholes options pricing model with the following weighted-average assumptions: risk free interest rate of 0.46% to 1.04%, expected dividend yield rate of 0%, expected volatility of 52.52% to 65.71% and an expected life between 5.5 and 7.5 years.

Pursuant to a second amendment to the 2018 Promissory Note in February 2019, the maturity date was extended to July 31, 2019 with all other provisions remaining unchanged. Pursuant to a third amendment to the 2018 Promissory Note in July 2019, the maturity date was extended to January 31, 2020 with all other provisions remaining unchanged. Pursuant to a fourth amendment to the 2018 Promissory Note in December 2019, the maturity date was extended to December 31, 2021, the note was modified to become secured by company assets, with all other provisions remaining unchanged. At September 30, 2021, accrued interest on the 2018 Promissory Note totaled $24,770.

In April 2019, one of the prepaid revenue customers requested a refund of the amounts paid. The Company entered into a note agreement to repay $2,182,142 over the next 12 months. The modification was necessary to address the delays to cobalt delivery in 2019 caused by changes to the ATR operating schedule and also to accommodate this customer’s request to reduce their cobalt purchase obligations in future years. The modifications require that the Company refund approximately $1,100,000 of payments received for prior year undelivered material, plus interest at 12% per year, payable over a one-year period on a portion of that amount. The Company has also agreed with this customer to refund approximately $1,100,000 paid for material that was to have been delivered in later years. There will be no interest charge on this refund. In December 2019, this agreement was modified further allowing the Company to delay the original payments by 3 months and refund an additional $462,258 with no interest charge. At September 30, 2021 balance on this refund is $109,994 and is included in short-term notes payable.

On December 20, 2019, the Company entered into a promissory note agreement with four of the Company’s major shareholders (the 2019 Promissory Note). The 2019 Promissory Note authorizes the Company to borrow up to $1,000,000. As of December 31, 2019, the Company had borrowed $675,000 under the 2019 promissory note. In February 2020, the Company borrowed an additional $325,000. The 2019 Promissory Note bears an interest rate of 4% annually and is due December 31, 2022. According to the terms of the 2019 Promissory Note, at any time, the lenders may settle any or all of the principal and accrued interest with shares of the Company’s common stock based on the average closing price of the Company’s common stock for the 20 days preceding the payment. In connection with the 2019 Promissory Note, the lenders were issued warrants totaling 30,000,000 warrants to purchase shares of the Company’s common stock at $0.045 per share (the Class O Warrants). The fair value of these Class O Warrants issued totaled $446,079 and was recorded as a debt discount and will be amortized over the life of the 2019 Promissory Note. The Company calculated a beneficial conversion feature of $315,643 which will be accreted to interest expense over the life of the 2019 Promissory Note. At September 30, 2021 accrued interest on the 2019 Promissory Note totaled $69,131.

In March 2021, one of the Company’s subsidiaries, RadQual, entered into a promissory note (the March 2021 Promissory Note) for the purchase of equipment. The principal amount under the March 2021 Promissory Note totals $101,250, bears interest at 5%, is secured by equipment, and is due March 2023.

RadQual

In April 2021, the Company borrowed $250,000 from our Chief Executive Officer and Chairman of the Board pursuant to a promissory note (the April 2021 Promissory Note). The April 2021 Promissory Note bears an interest rate of 6% annually and is due December 31, 2022. At any time, the holder of the April 2021 Promissory Note may elect to have any or all of the principal and accrued interest settled with shares of the Company’s common stock based at the price of $0.11 per share. At September 30, 2021 accrued interest on the April 2021 Promissory Note totaled $7,000.

(8) Commitments and Contingencies

Dependence on Third Parties

The production of High Specific Activity Cobalt is dependent upon the DOE, and its prime operating contractor, which controls the ATR and laboratory operations at the ATR located outside of Idaho Falls, Idaho. In October 2014, the Company signed a ten-year contract with the DOE for the irradiation of cobalt targets for the production of cobalt-60. The Company will be able to purchase cobalt targets for a fixed price per target with an annual 5% escalation in price. The contract term is October 1, 2014, through September 30, 2024, however, the contract may be extended beyond that date. Also, the DOE may end the contract if it determines termination is necessary for the national defense, security or environmental safety of the United States. If this were to occur, all payments made by the Company, for partially irradiated undelivered cobalt material, would be refunded.

Sales of our most predominant radiochemical products are dependent upon a few key suppliers. An interruption in production by any of these individual suppliers could have an immediate negative impact upon radiochemical sales until material can be purchased from alternate suppliers including obtaining regulatory approval to use material from alternative suppliers if necessary.

Nuclear Medicine Reference and Calibration Standard manufacturing is conducted under an exclusive contract with RadQual, which in turn has an agreement in place with several companies for distributing the products. The radiochemical product sold by the Company is supplied to the Company through agreements with two suppliers. A loss of any of these customers or suppliers could adversely affect operating results by causing a delay in production or a possible loss of sales.

Contingencies

Because all the Company’s business segments involve the handling or use of radioactive material, the Company is required to have an operating license from the NRC and specially trained staff to handle these materials. The Company has amended this operating license numerous times to increase the amount of material permitted within the Company’s facility. Although this license does not currently restrict the volume of business operations performed or projected to be performed in the upcoming year, additional processing capabilities and license amendments could be implemented that would permit processing of other reactor-produced radioisotopes by the Company. The financial assurance required by the NRC to support this license has been provided for with a surety bond held with North American Specialty Insurance Company which is supported by a restricted money market account held with Merrill Lynch in the amount of $830,736.

In August 2011, the Company received land from Lea County, New Mexico, pursuant to a Project Participation Agreement (PPA), whereby the land was deeded to the Company for no monetary consideration. In return, the Company committed to construct a uranium de-conversion and Fluorine Extraction Process facility on the land. In order to retain title to the property, the Company was to begin construction of the de-conversion facility no later than December 31, 2014, and complete Phase I of the project and have hired at least 75 persons to operate the facility no later than December 31, 2015, although commercial operations need not have begun by that date. In 2015, the Company negotiated a modification to the PPA that extended the start of construction date to December 31, 2015, and the hiring milestone to December 31, 2016. Those dates were also not met. The Company has been in discussion with commercial companies to explore their interest in purchasing rights to this project. Should those discussions come to fruition the Company plans to negotiate a second modification to the PPA agreement to further extend the commitment dates. If the Company is not successful in reaching an amendment to extend the performance dates in the PPA. then it may, at its sole option, either purchase or re-convey the property to Lea County, New Mexico. The purchase price of the property would be $776,078, plus interest at the annual rate of 5.25% from the date of the closing to the date of payment. The Company has not recorded the value of this property as an asset and will not do so until such time that sufficient progress on the project has been made to meet the Company’s obligations under the agreements for permanent transfer of the title.

On May 2, 2019, the Company’s radiological services team was involved in a contamination event involving a breached cesium-137 source at an off-site location in the state of Washington. This work was being performed under a contract with the DOE. The Company supported the initial onsite contamination clean-up operations at that location and completed removal of the cesium source and Company equipment. On January 5, 2021, the Company was notified by the DOE that the Company has been indemnified from any financial liability for this event under the Price Anderson Act (PAA). As part of this indemnification notification, the Company received payment in full for its claim with the DOE for recovery of certain expenses incurred for this event. The Company recognized Other Income of approximately $150,000 in the nine months ended September 30, 2021, for additional cost recoveries for this event. All remaining cost recoveries as part of this settlement with the DOE were recognized in previous financial periods pursuant to ASC 410-30. The Company used these funds to pay all outstanding subcontractors and reimburse their insurance company for payments they previous paid the Company for this matter. The Company has concluded a final settlement with its insurance company and all others regarding this claim as of the date of this filing.

The Company’s corrective actions for this event included termination of all field service activities and removal of these activities from the Company’s NRC license. The Company believes that the loss in revenue resulting from suspension of radiological field service work will be compensated for by increased revenues in the Company’s remaining business segments.

The Company’s revenue consists primarily of calibration and reference standards manufactured for use in the nuclear medicine industry, distribution of radiochemicals including sodium iodide I-131 drug product, and cobalt source manufacturing. With the exception of certain unique products, the Company’s normal operating cycle is considered to be one year. Due to the time required to produce some cobalt products, the Company’s operating cycle for those products is considered to be two to three years. Accordingly, preliminary payments received on cobalt contracts, where shipment will not take place for greater than one year, have been recorded as unearned revenue on the Company’s condensed consolidated balance sheets and classified under current or long-term liabilities, depending upon estimated ship dates. For the nine months ended September 30, 2021, the Company reported current unearned revenue of $880,731. For the period ended December 31, 2020, the Company reported current unearned revenue of $1,160,274. These unearned revenues will be recognized as revenue in the periods during which the cobalt shipments take place.

Contract Balances

The Company records a receivable when it has an unconditional right to receive consideration after the performance obligations are satisfied. As of September 30, 2021, and December 31, 2020, accounts receivable totaled $1,043,721 and $796,128, respectively. For the nine months ended September 30, 2021, the Company did not incur material impairment losses with respect to its receivables.

(10) Leases

The Company leases office and warehouse space under operating leases. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments under the lease. Operating lease, right-of-use assets, and liabilities are recognized at the lease commencement date based on the present value of lease payments over the reasonably certain lease term. The implicit rates with the Company’s operating leases are generally not determinable and the Company uses its incremental borrowing rate at the lease commencement date to determine the present value of its lease payments. The determination of the Company’s incremental borrowing rate requires judgement. The company determines its incremental borrowing rate for each lease using its then-current borrowing rate. Certain of the Company’s leases include options to extend or terminate the lease. The Company establishes the number of renewal options periods used in determining the operating lease term based upon its assessment at the inception of the operating lease. The option to renew the lease may be automatic, at the option of the Company, or mutually agreed to between the landlord and the Company. Once the facility lease term has begun, the present value of the aggregate future minimum lease payments is recorded as a right-of-use asset. Lease expense is recognized on a straight-line basis over the term of the lease.

BUSINESS OVERVIEW

International Isotopes Inc., its subsidiaries (including RadQual, LLC) and joint venture, TI Services, LLC (collectively, the Company, we, our, or us) manufacture a full range of nuclear medicine calibration and reference standards, manufacture a range of cobalt products, and distribute sodium iodide I-131 as a generic drug. We own 100% interest of RadQual, LLC (RadQual), a global supplier of molecular imaging quality control and calibration devices.

RADQUAL ACQUISTION

On July 8, 2021, we entered into a Membership Interest Purchase Agreement (the Purchase Agreement) with RadQual and the sellers set forth in the Purchase Agreement, which included our Chairman of the Board, Chief Executive Officer, former Chairman of the Board, and certain other stockholders of the Company (collectively, the Sellers). Pursuant to the Purchase Agreement, we acquired all of the outstanding membership interests of RadQual not then-owned by the Company for an aggregate purchase price of approximately $4.4 million, payable in shares of our common stock valued at $0.11 per share (determined by the average trading price of our common stock on the OTC Markets during the 60 trading day period immediately prior to June 2, 2021) (the RadQual Acquisition). We issued an aggregate of 40,176,236 shares of its common stock to the Sellers as consideration in the RadQual Acquisition. Prior to the RadQual Acquisition, we owned approximately 24.5% of the outstanding membership interests of RadQual, and after acquiring all of the remaining membership interests of RadQual, RadQual became a wholly-owned subsidiary of the Company. The RadQual Acquisition closed on July 8, 2021.

Our business consists of the following five business segments:

Nuclear Medicine Standards. Our Nuclear Medicine Standards segment consists of the manufacture of sources and standards associated with Single Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET) imaging. These sources are used for indication of patient positioning for SPECT imaging, SPECT camera operational testing, and calibration of dose measurement equipment. Revenue from nuclear medicine products includes consolidated sales from TI Services, LLC (TI Services), a 50/50 joint venture that we formed with RadQual in December 2010 to distribute our products, as well as consolidated sales from RadQual. Our nuclear medicine standards products include a host of specially designed items used in the nuclear medicine industry. In addition to the manufacture of these products, we have developed a complete line of specialty packaging for the safe transport and handling of these products.

Cobalt Products. Our Cobalt Products segment includes the production of bulk cobalt (cobalt-60), fabrication of cobalt capsules for radiation therapy and various industrial applications, and recycling of expended cobalt sources. We are the only company in the U.S. that can provide all these unique services. There has been a significant increase in regulation by the Nuclear Regulatory Commission (NRC) in recent years that has created a significant barrier to new entrants into this market. The Company has a contract in place with the U.S. Department of Energy (DOE) for the production of high specific activity cobalt in the Advanced Test Reactor (ATR) in Idaho. This agreement will be in effect until October 2024.

Radiochemical Products. Our Radiochemical Products segment includes production and distribution and FDA approved generic sodium iodide I-131 drug product for the treatment of hyperthyroidism and carcinoma of the thyroid. We are the only U.S. Company distributing this generic drug product. This segment also includes distribution of certain other radiochemical products and contract manufacturing of radiopharmaceutical products for our customers.

Fluorine Products. We established the Fluorine Products segment in 2004 to support production and sale of the gases that we expected to produce using our Fluorine Extraction Process (FEP) in conjunction with the operation of the proposed depleted uranium de-conversion facility in Lea County, New Mexico. Near the end of 2013, due to changes in the nuclear industry, we placed further engineering work on this project on hold. We continue to hold discussions with potential future customers seeking this type of service, however, further development activity within this segment will be deferred until market and industry conditions change to justify resuming design and construction of the facility. In the meantime, the Company expects to continue to incur some costs associated with the maintenance of licenses and other necessary project investments, and to continue to keep certain agreements in place that will support resumption of project activities at the appropriate time.

Radiological Services. Our Radiological Services segment consisted of a wide variety of miscellaneous services such as decommissioning disused irradiation units, performing sealed source exchanges in irradiation and therapy units, and gemstone processing. The Company has suspended all of its field service activities and is in the process of terminating gemstone processing. The Company believes that eliminating work in the Radiological Services segment will allow the Company to better focus upon our core business segments and our new products pipeline. We believe that the loss in revenue resulting from wrapping up of radiological field service work will be more than offset by increased revenues in our remaining business segments.

COVID-19 UPDATE

As a result of the COVID-19 pandemic, we continue to experience a reduction of sales within our nuclear medicine calibration standards segment and radiochemicals segment during the nine-months ended September 30, 2021. There was no discernable impact from COVID-19 to our cobalt products business segment during the period. The decrease in sales for the nine months ended September 30, 2021 for our radiochemical segment was the result of delays in patient treatment. The sale of nuclear medicine reference and calibration standards increased during the nine month period, however, we believe the increase in revenue would have been greater were it not for the continued negative impact of COVID-19 which resulted in the temporary closure of many imaging clinics and suspension of elective or non-essential imaging procedures.

To-date we have not furloughed or terminated any employees as a result of the financial impact of COVID-19. The Company has only seen a limited impact in our raw material supply chain related to the COVID-19, primarily some plastics which have been in strong demand for certain types of PPE. Alternative sources of raw materials have been obtained without any interruption to production. With the heightened concern about corporate liquidity during the COVID-19 pandemic, the Company believes that it has adequate cash to support continuing operations.

For the three months ended September 30, 2021, we accrued dividends payable of $57,620, which have been recorded as interest expense. Additionally, non-cash interest expense in the amount of $34,400 was recorded for this same period for the issuance of warrants related to the preferred stock issuances. See Note 7 “Debt” to our unaudited condensed consolidated financial statements in this Quarterly Report for additional information about our indebtedness and the associated interest expense.

Our net loss for the three months ended September 30, 2021, was ($136,869), compared to net income of $307,050, for the same period in 2020. This is a decrease of income of $443,919 is the result of increased cost of sales and operating expenses in the three months ended September 30, 2021 as compared to the same period in 2020.

Radiochemical Products. Revenue from the sale of radiochemical products for the three months ended September 30, 2021 was $1,210,615, compared to $1,294,546 for the same period in 2020. This is a decrease of $83,931, or approximately 6%. The decrease is a result of a reduction in payments received for contract manufacturing services in the 2021 three-month period compared to 2020.

Gross profit of radiochemical products for the three months ended September 30, 2021 was $751,271, compared to $847,372, for the same period in 2020, and gross profit percentages were approximately 62% and 65% for the three months ended September 30, 2021 and 2020, respectively. This decreased gross profit percentage is a result of increased cost of raw materials. Cost of sales for radiochemical products increased to $459,344 for the three months ended September 30, 2021, as compared to $447,174 for the same period in 2020. This is an increase of $12,170, or approximately 3%, and was primarily the result of increased cost of raw material. Operating expense for this segment increased to $380,684 for the three months ended September 30, 2021, compared to $304,559 for the same period in 2020. This increase in operating expense of $76,125, or approximately 25%, is primarily due to increased costs for licenses and permits related to our FDA approved radiopharmaceutical product. This segment reported net income of $370,586 for the three months ended September 30, 2021, as compared to net income of $542,814 for the same period in 2020. The decrease in net income of $172,228 or approximately 32%, is primarily the result of the increased cost of sales and operating expenses during the three months ended September 30, 2021.

Cobalt Products. Revenue from the sale of cobalt products for the three months ended September 30, 2021 was $408,808, compared to $544,989, for the same period in 2020. This represents an decrease of $136,181, or approximately 25%. The decrease is due to timing of cobalt demand and our ability to procure material for this demand. The decrease is also due to recognition of income for cobalt provided under our cobalt-60 supply agreements as described below.

In October 2014, we entered into a ten-year agreement with the DOE for the irradiation of cobalt targets. The agreement gives us the ability to purchase the current full capacity of the DOE’s ATR throughout the ten-year period. It takes many years to irradiate these cobalt targets to the desired level of activity. Production calculations indicated we should have been able to anticipate having high specific activity cobalt available for our customers in late 2019. However, extended reactor shutdowns and lower than expected production rates of cobalt-60 in the new design cobalt targets delayed delivery of high specific activity cobalt until May 2021. Future delivery dates of high activity cobalt are uncertain at present. However, the Company has been able to acquire additional cobalt material from the DOE in lower activity ranges to satisfy some customers’ needs.

During 2015, we entered into cobalt-60 supply agreements with several customers. The terms of the agreements required pre-payments to secure cobalt material in future years. Those prepayments were recorded as unearned revenue on our condensed consolidated balance sheet.

Cost of sales for the three months ended September 30, 2021, was $148,855, as compared to $126,677, for the same period in 2020.

Operating expense in this segment increased to $93,145 for the three months ended September 30, 2021, from $75,588 for the same period in 2020. This is an increase of $17,557, or approximately 23%. This increase in operating expenses for the three months ended September 30, 2021 is due to increased support labor from increased shipment activity. Our net income for cobalt products was $166,808 for the three months ended September 30, 2021, as compared to a net income of $342,724 for the same period in 2020. The decrease in net income of $175,916, or approximately 51%, was attributable to timing of cobalt demand and our ability to procure material for this demand.

Nuclear Medicine Standards. Revenue from nuclear medicine products for the three months ended September 30, 2021, was $973,439, compared to $958,293 for the same period in 2020. This represents an increase in revenue of $15,146, or approximately 2%. As discussed above, due to a change in the ownership of RadQual, in August 2017 we began reporting our investment in RadQual on a consolidated basis. In July 2021, we acquired all remaining interest in RadQual. Therefore, revenue in this segment includes all sales of RadQual and TI Services with all intercompany sales for the consolidated period eliminated. The increase in sales for the period ended September 30, 2021 was due to increased order activity as recovery from the COVID-19 pandemic continues.

Cost of sales for our nuclear medicine standards segment for the three months ended September 30, 2021, was $398,112, as compared to $395,148 for the same period in 2020.

Gross profit for our nuclear medicine standards segment for the three months ended September 30, 2021 was $575,327 compared to $563,145 for the same period in 2020. This is an increase in gross profit of $12,182, or approximately 2%. The increase in gross profit in the period-to-period comparison is primarily the result of the increased sales. Our gross profit percentages were approximately 59% and 59% for the three-month periods ended September 30, 2021 and 2020, respectively.

Operating expense for this segment for the three months ended September 30, 2021 increased to $454,875, from $432,648 for the same period in 2020. This is an increase of $22,227, or approximately 5%, and is the result of increased expenses for production supplies, support labor expenses, and operating expenses related to RadQual as compared to the same period in 2020. Operating expense includes consolidated net operating expense reported for RadQual of $143,480 and non-controlling member interest expense of $7,812, for the three months ended September 30, 2021, as compared to $136,661 of net operating expense and non-controlling member interest expense of $63,309 for the same period in 2020. The decrease in non-controlling member interest expense was due to our purchase of all remaining interest in RadQual in July 2021. Net operating expense included for TI Services was $22,048 for the three months ended September 30, 2021, and $22,486 for the same period in 2020. TI Services non-controlling interest included was ($3,537) for the three-month period ended September 30, 2021, as compared to $22,154 for the same period in 2020.

Net income for this segment for the three months ended September 30, 2021 was $120,452, compared to $181,097 for the same period in 2020. This is a decrease in net income of $60,645, or approximately 33% and is a result of other income of $50,600 in 2020 as compared to $0 in 2021.

Radiological Services. Revenue from all radiological services for the three months ended September 30, 2021 was $16,889, compared to $54,760, for the same period in 2020, a decrease of $37,871 or approximately 69%. The decrease in the revenue for the period comparison is the result of decreased gemstone processing activity from the wrapping up of this contract work.

On May 2, 2019, our radiological services team was involved in a contamination event involving a breached cesium-137 source at an off-site location in the state of Washington. This work was being performed under a contract with the DOE. Beginning in August 2019, the DOE assumed full control of the cleanup operations and assumed all the financial obligations associated with the contractors hired to carry out all remaining facility recovery operations. On January 5, 2021, we were notified by the DOE that we have been indemnified from any financial liability for this event under the Price Anderson Act (PAA). We also have reached a final settlement with our insurance company regarding this claim.

In January 2020, we notified our gemstone processing customer that the service contract with them was being terminated because the volume of gemstones sent for processing did not meet contract minimums. The termination activities and wrap up of this service will continue throughout 2021 and the Company expects to see a steady decline in revenue from this service as production is wrapped up. We plan to convert the spaces in the facility that had been used to perform this contract work into expanded Nuclear Medicine product manufacturing. The loss in revenue expected from termination of the gemstone processing agreement is expected to be more than compensated for by the expansion of new nuclear medicine source products.

The decrease in gross profit of $32,011, or approximately 65%, is the result of decreased activity of gemstone processing for the three months ended September 30, 2021, as compared to the same period in 2020. We expect our costs of sales to continue to be very low going forward. Operating expense for the three months ended September 30, 2021 was $4,133 as compared to $14,731, reported for the same period in 2020. This decrease of $10,598, or approximately 72%, is the result of decreased sales and activity within the business segment.

Net income for this segment for the three months ended September 30, 2021 was $12,733, compared to net income of $34,145, for the same period in 2020. This is a decrease in net income of $21,412 is the result of decreased sales and activity within the business segment.

Fluorine Products. For the three months ended September 30, 2021, we had revenues related to Fluorine Products of $7,763 as compared to $11,700 for the same period in 2020. These revenues were related to an agreement to provide engineering and technical assistance services related to our fluorine products intellectual property. During the three months ended September 30, 2021, we incurred $34,348 of expense related to items in support of future planning and design for the proposed de-conversion facility, as compared to $38,340 for the same three-month period in 2020. This is a decrease of 10% in the period-to-period comparison.

We established the Fluorine Products segment in 2004 to support production and sale of the gases produced using our fluorine extraction process (FEP). The project has been placed on hold since 2013 and we will continue to limit our expenditures to essential items such as maintenance of the NRC license, land use agreements, communication with our prospective FEP product customers, and interface with the State of New Mexico and Lea County officials until such time that we decide to resume the project.

Our gross profit percentages were approximately 59% and 75% for the nine-month periods ended September 30, 2021 and 2020, respectively. The decrease in the gross profit percentage for the nine months ended June 30, 2021 is primarily due to increased costs of raw material used in the manufacture of sealed sources. Operating expense in this segment increased to $302,828 for the nine months ended September 30, 2021, from $262,673 for the same period in 2020. This is an increase of $40,155, or approximately 15% is a result of increased equipment expenses in the nine months ended September 30, 2021 as compared to the same period in 2020. Our net income for cobalt products was $345,292 for the nine months ended September 30, 2021, as compared to a net income of $542,394 for the same period in 2020. The decrease in net income of

$197,102 or approximately 36%, was attributable to the increase in operating expenses for the nine months ended September 30, 2021, as compared to the same period in 2020.

Nuclear Medicine Standards. Revenue from nuclear medicine products for the nine-month period ended September 30, 2021 was $2,988,326 compared to $2,778,290 for the same period in 2020. This represents an increase in revenue attributable to this segment of $210,036, or approximately 8%. The increase in sales for the period ended September 30, 2021 was due to increased order activity and sales of some new products as recovery from the Covid-19 pandemic continues. As discussed above, due to a change in the ownership of RadQual, in August 2017 we began reporting our investment in RadQual on a consolidated basis. In July 2021, we acquired all remaining interest in RadQual. Therefore, revenue in this segment includes all sales of RadQual and TI Services with all intercompany sales for the consolidated period eliminated.

Gross profit for the nine-month period ended September 30, 2021 was $1,687,047, as compared to $1,577,988 for the same period in 2019, a decrease of $109,059, or approximately 7%. Operating expense for this segment for the nine-month period ended September 30, 2021 increased to $1,303,841, from $1,145,134 for the same period in 2020. This is an increase of $158,707 or approximately 14% and includes consolidated net operating expense reported for RadQual of $448,381 and non-controlling member interest expense of $116,765, for the nine months ended September 30, 2021, compared to consolidated net operating expense of $414,849 and non-controlling member interest expense of $145,533, for the nine months ended September 30, 2020. Other Income for the nine months ended September 30, 2021, was $0. For the nine months ended September 30, 2020, Other Income for this segment included $50,600 of income from a TI Services SBA Loan converted to grant income. Net income for this segment for the nine-month period ended September 30, 2021, decreased to $383,207, approximately 21%, from $483,454 for the same nine-month period in 2020.

Radiological Services. Revenue from all radiological services for the nine months ended September 30, 2021 was $147,644, compared to $171,048, for the same period in 2020, a decrease of $23,404 or approximately 14%. The decrease in the revenue for the period comparison is the result of decreased gemstone processing activity.

On May 2, 2019, our radiological services team was involved in a contamination event involving a breached cesium-137 source at an off-site location in the state of Washington. On January 5, 2021, we were notified by the DOE that we have been indemnified from any financial liability for this event under the Price Anderson Act (PAA). As part of this indemnification notification, we received payment in full for our claim with the DOE for recovery of certain expenses incurred for this event. We recognized Other Income of approximately $150,000 in the six months ended June 30, 2021 for additional cost recoveries for this event. All remaining cost recoveries as part of this settlement with the DOE were recognized in previous financial periods pursuant to ASC 410-30. These funds were used to pay all outstanding subcontractors and reimburse our insurance company for payments they previous paid us for this matter. In October 2021, we reached a final settlement with our insurance company regarding this claim.

Cost of sales for the nine months ended September 30, 2021, was $368, as compared to $39,221, for the same period in 2020. Gross profit for this segment for the nine months ended September 30, 2021 was $147,276, compared to $131,827, reported for the same period in 2020. The increase in gross profit of $15,449, or approximately 12%, is the result of decreased costs for gemstone processing for the nine months ended September 30, 2021, as compared to the same period in 2020. Operating expense for the nine months ended September 30, 2021 was $23,893 as compared to $126,142, reported for the same period in 2020. This decrease of $102,249, or approximately 81%, is the result of decreased sales and activity within the business segment.

Net income for this segment for the nine months ended September 30, 2021 was $123,383, compared to net loss of $5,684, for the same period in 2020. This is an increase in net income of $117,699 and is the result in the increase in gross profit and decreased operating expenses for the same period in 2020.

Fluorine Products. For the nine months ended September 30, 2021, we had revenues related to Fluorine Products of $29,775 compared to $172,200, for the same period in 2020, a decrease of $142,425 or approximately 83%. These revenues were related to an agreement to provide engineering and technical assistance services related to our fluorine products intellectual property. During the nine months ended September 30, 2021, we incurred $121,500 of expense related to items in support of future planning and design for the proposed de-conversion facility, as compared to $112,430 for the same nine-month period in 2020. This is an increase of 8% in the period-to-period comparison.

We established the Fluorine Products segment in 2004 to support production and sale of the gases produced using our Fluorine Extraction Process (“FEP”). We will continue to limit our expenditures to essential items such as maintenance of the NRC license, land use agreements, communication with our prospective FEP product customers, and interface with the State of New Mexico and Lea County officials.

LIQUIDITY AND CAPITAL RESOURCES

At September 30, 2021, we had cash and cash equivalents of $753,526 as compared to $1,113,032 at December 31, 2020. This is a decrease of $359,506 or approximately 32%. For the nine months ended September 30, 2021, net cash provided in operating activities was $64,294 and net cash provided for the nine months ended September 30, 2020 in operating activities was $960,314. The decrease in cash provided in operating activities and decrease in cash and cash equivalents at period end in the period-to-period comparison is the result of increased net loss and decreased accounts payable.

Inventories at September 30, 2021 totaled $582,298, and inventories at December 31, 2020 totaled $837,787. Previously, a significant amount of our inventory consisted of work-in-process cobalt raw material held at the ATR located outside of Idaho Falls, Idaho. Work in process includes costs to irradiate cobalt-60 material under a contract with the DOE. This material has been placed in the ATR and the Company made progress payments to purchase this material which was completed during the second quarter of 2021. At September 30, 2021, this raw cobalt material inventory at the ATR accounted for approximately 0% of our work-in-process inventory. At December 31, 2020, this in-process raw material inventory accounted for approximately 46% of our work in process inventory.

Cash used in investing activities was $196,730 for the nine months ended September 30, 2021, and cash provided in investing activities was $1,756 for the same period in 2020. The cash used in the nine months ended September 30, 2021 was for the purchase of equipment.

Financing activities used cash of $34,994, during the nine months ended September 30, 2021, and cash used by financing activities for the same period in 2020 was $636,136. During the nine months ended September 30, 2021, cash paid for interest was $69,042 and during the same six-month period in 2020, cash paid for interest was $67,575. Additionally, during the nine months ended September 30, 2021, we received $13,528 in proceeds from the sale of our common stock through our Employee Stock Purchase Plan, as compared to $13,430 for the same period in 2020.

In February 2021, the Company paid its third annual dividend on the Series C Preferred Stock. Dividends payable totaled $254,280. Some holders of the Series C Preferred Stock elected to settle their dividend payments with shares of the Company’s common stock in lieu of cash. The Company issued 1,398,200 shares of common stock in lieu of a dividend payment of $207,480. The remaining $46,800 of dividend payable was settled with cash.

Total decrease in cash for the nine-month period ended September 30, 2021, was $167,430 compared to a cash increase of $325,934 for the same period in 2020.

We expect that cash from operations, cash raised via equity or debt financings, and our current cash balance will be sufficient to fund operations for the next twelve months. Our future liquidity and capital funding requirements will depend on numerous factors, including, contract manufacturing agreements, commercial relationships, technological developments, market factors, available credit, our ability to raise additional capital and voluntary warrant redemption by shareholders. There is no assurance that additional capital and financing will be available on acceptable terms to the Company or at all, especially in light of the market volatility and uncertainty as a result of the COVID-19 pandemic.

At September 30, 2021, there were 7,065,000 outstanding warrants to purchase our common stock. Included in this number are 4,140,000 Class M Warrants issued February 17, 2017, with an exercise price of $0.12 per share and an expiration date of February 17, 2022; and, 2,925,000 Class N Warrants issued May 12, 2017, with an exercise price of $0.10 per share and an expiration date of May 12, 2022.

According to the terms of the 2019 Promissory Note, at any time, a holder of the 2019 Promissory Note may elect to have any or all of the principal and accrued interest settled with shares of our common stock based on the average price of the shares over the previous 20 trading days. In connection with the 2019 Promissory Note, we issued 30,000,000 Class O Warrants to purchase shares of our common stock at $0.045 per share (the Class O Warrants). The Class O Warrants were exercisable at an exercise price of $0.045 per share and had a term of five years. In January 2021, all 30,000,000 Class O Warrants were exercised. At September 30, 2021, accrued interest on the 2019 Promissory Note totaled $69,131.

The SBA Loan was scheduled to mature on April 22, 2022 and had a 1.00% interest rate and was subject to the terms and conditions applicable to loans administered by the SBA under the CARES Act.

In July 2021, we received notification from the SBA that we received approval of forgiveness of the entire loan.
