PART I

Item 1.

BUSINESS

General Business and Products Description

International Isotopes Inc. (the “Company”, “we”, “us” and “our”) manufactures a full range of nuclear medicine calibration and reference standards, a wide range of products, including cobalt teletherapy sources, and a varied selection of radioisotopes and radiochemicals for medical research, pharmacy compounding, and clinical applications. We also provide a host of transportation, recycling, and processing services on a contract basis for customers.

We were formed as a Texas corporation in 1995.  Our wholly-owned subsidiaries are International Isotopes Idaho Inc., a Texas corporation; International Isotopes Fluorine Products, Inc., an Idaho corporation; and International Isotopes Transportation Services, Inc., an Idaho corporation.  Our core business consists of five reportable segments which include: Nuclear Medicine Standards, Cobalt Products, Radiochemical Products, Fluorine Products, and Radiological Services.

During 2018, we focused our efforts on achieving profitability in each of our core business segments and reached several significant goals.  During 2018, we:

·

Increased revenue by approximately 40% and reduced our net loss by approximately 78%;

·

Pursued and were awarded numerous field service jobs through the Department of Energy’s (DOE) Orphan Source Recovery Program (OSRP) and other domestic programs using our mobile hot cell and highly experienced personnel and increased revenue in the Radiological Services segment by approximately 67%;

·

Contracted with an alternate supplier of cobalt-60 to fulfill cobalt contract obligations and meet customer demand for various types of sealed source products, which increased our revenue in the Cobalt Products segment by approximately 302%;

·

Expanded sales of our nuclear medicine products through exercising our management opportunity with RadQual, LLC (RadQual).  In particular, we increased our international sales by utilizing the marketing and distribution expertise of our joint venture with RadQual, TI Services, LLC (TI Services);

·

Supported the review by the U.S. Food and Drug Administration (FDA) of our abbreviated new drug application (aNDA) which was submitted to the FDA with a request for expedited review; and

·

Maintained our relationships in Lea County, New Mexico (location of our proposed de-conversion facility) and continued to pursue opportunities to obtain additional contracts for depleted uranium de-conversion services related to our proposed de-conversion project.

1

In 2019, we plan to continue efforts to further expand and improve upon our operations in our core business segments. We intend to continue to invest in these segments and work to pursue product development, reduce production costs and expand sales in each of them.  The following paragraphs provide a brief description of each of our business segments.  Certain financial information with respect to each of our business segments, including revenues from external customers, a measure of profit or loss, and total assets, is set forth in Note 15 to our Consolidated Financial Statements which begin on page F-7.

Nuclear Medicine Standards

This segment consists of the manufacture of sources and standards associated with Single Photon Emission Computed Tomography (SPECT) imaging, patient positioning, and calibration or operational testing of dose measuring equipment for the nuclear pharmacy industry. Our nuclear medicine standards products include flood sources, dose calibrators, rod sources, flexible and rigid rulers, spot markers, pen point markers, and a host of specialty design items.  These products are manufactured through an exclusive manufacturing agreement with RadQual, of which we own a 24.5% interest. In August 2017, affiliates of the Company purchased the remaining 75.5% interest of RadQual and at that time we were named as one of two managing members of RadQual.  As a result of this ownership change, we gained significant influence in management decisions with regard to RadQual’s business operations. We have a manufacturing agreement with RadQual, that will remain in place and provides that we will manufacture sources exclusively for RadQual and will not manufacture products that would directly compete with RadQual sources.

There are over 5,000 nuclear medicine centers in the United States (U.S.) that require nuclear medicine products on a regular repeat basis.  We have been manufacturing these products for RadQual since 2001. The majority of nuclear medicine product sales are to U.S. customers; however, in recent years, as a result of stronger marketing efforts, we have seen an increase in foreign sales, as shown in Note 14 to the accompanying audited financial statements. All of these products contain radioactive isotopes that decay at a predictable rate. Therefore, customers are required to periodically replace most of these products when they reach the end of their useful lives. The useful life of these products varies depending on the isotope used in manufacture, but in most cases averages eighteen months to two years. The isotopes used in manufacturing these nuclear medicine products are available from various sources world-wide and we are not dependent on a single supplier.  In addition to the products themselves, we have developed a complete line of specialty packaging for the safe transportation and handling of these products.

RadQual has numerous distributors for direct sales of its products. Formerly, the largest distributor was Technology Imaging Services Inc. (TIS). In December 2010, we formed a 50/50 joint venture with RadQual to acquire the assets of TIS, and those assets were used to create TI Services LLC.  This joint venture has provided sales opportunities in existing and future RadQual product lines both domestically and internationally as a marketer for RadQual products.

Cobalt Products

Our cobalt products segment includes the production of bulk cobalt (cobalt-60), fabrication of cobalt capsules for radiation therapy as well as various industrial applications, and recycling of expended cobalt sources.

Although bulk cobalt sales have historically accounted for a significant amount of the total revenue from this business segment, during the past several years we have not had any bulk sales because of an interruption in cobalt production in the DOE’s Advanced Test Reactor (ATR) located in Idaho.  Through continued work with the DOE, a new cobalt target was designed and in October 2014 we entered into a ten-year agreement with the DOE for the irradiation of the new target design. We had expected our supply of cobalt material from the ATR to resume in 2018.  However, due to extended reactor shut-downs during the year, we now expect our supply of cobalt material from the ATR to resume by the third quarter of 2019. Subsequent to completing the agreement with the DOE, we entered into contracts with several customers for the sale of this material.  In accordance with those agreements, we began receiving pre-payments from customers on future cobalt shipments which we recorded as unearned revenue.  To fulfill our supply agreements with these customers, we were able to identify a secondary supplier of cobalt to satisfy the terms of our supply agreements.  Accordingly, at the time of shipment, customer payments previously recorded as deferred revenue were reclassified as revenue.

The year-over-year demand for cobalt products has remained strong as a result of the introduction of several new types of cobalt therapy units and we have continued to see demand for cobalt-manufactured products for those devices. We have explored and intend to continue to explore, opportunities to further develop cobalt products and sales on an on-going basis.  The production, use, transport, and import/export of these products are all heavily regulated, but we have developed an experienced staff of technicians, drivers, and supervisors as part of our efforts to comply with the regulations as well as support cost effective and timely delivery of these products.

At the present time, we are the sole producer of high activity cobalt from any of the DOE reactors in the U.S.  There are a few other cobalt source manufacturers in North America, but we believe both our product and service provide us with a competitive edge in competing with these other manufacturers.

2

We also own older cobalt targets stored at the ATR that hold significant market value to us assuming the material is recoverable.  Through working with the DOE, we have determined a feasible and cost-effective method of transfer and shipping for these targets and hope to begin shipping them to our facility in third quarter 2019.  We will re-evaluate the market value of all remaining older material at the end of 2019.

Radiochemical Products

This segment includes the production and distribution of various isotopically pure radiochemicals for medical, industrial, and research applications.  These products are either directly produced by us or are purchased in bulk from other producers and distributed by us in customized packages and chemical forms tailored to meet customer and market demands. Sodium Iodide (Iodine-131) radiochemical product accounts for the largest portion of sales within this segment.  Our generic sodium iodide drug product will be the only generic product of this type manufactured in North America and we believe the product will offer customers an attractive alternative to the single existing commercial drug product being sold in the U.S.  We have several suppliers of sodium iodide from whom we purchased material during 2018.

Other less significant sales of radiochemical products in this segment consist of sales of isotopes such as Cobalt-57 (Co-57), Cesium-137 (Cs-137), Germanium – 68 (Ge-68), Sodium-22 (Na-22), and Barium-133 (Ba-133).

Radiological Services

This segment includes a wide variety of services such as decommissioning disused irradiation units, performing sealed source exchanges in irradiation and therapy units, and processing gemstones.

We are licensed through the Nuclear Regulatory Commission (NRC) to perform certain field service activities in connection with the DOE’s Orphan Source Recovery Program (OSRP).  These activities include services to support recovery of disused sources under the DOE’s OSRP and installation or removal of certain cobalt therapy units. We designed and built a mobile hot cell unit to use in this field service work and during 2018 and 2017 we used the unit extensively to perform numerous OSRP field service jobs. The unique design of our mobile hot cell allows us to modify the hot cell’s interface with various therapy units or transportation containers in order to perform customized source removal which provides us with a significant competitive advantage over other techniques. Additionally, this unit has allowed us to expand our field service work to include similar international contract opportunities through the International Atomic Energy Agency (IAEA).  As anticipated, this type of field service work generated the majority of revenue within this business segment during 2018 and we expect the same in the coming years.

Fluorine Products and the Planned Uranium De-Conversion Facility

In 2004, we began a major undertaking to construct the first commercial uranium de-conversion facility in the U.S.  At that time, we believed that such an undertaking would provide an excellent commercial opportunity to us in the future.

DUF6 is the waste by-product of uranium enrichment and any uranium enrichment facility will create very large quantities of DUF6.  Our intended plant design would process DUF6 into DUF4 and then use the DUF4 in the FEP process, thereby, creating a business model in which we would be paid to process the DUF6 and then would be able to sell the fluoride products produced from the DUF4.

We established the fluorine products business segment in 2004 to support production and sale of the gases produced using our Fluorine Extraction Process (FEP) that we intended to use in conjunction with the operation of the proposed depleted uranium de-conversion facility in Lea County, New Mexico.  The FEP is a process that produces ultra-high-purity fluoride gas products through a solid-to-solid reaction between depleted uranium tetrafluoride (DUF4) and various solid metal oxides such as silicon. High-purity fluoride gases are in high demand for processes such as ion-implantation and chemical vapor deposition and also for the manufacture of organic complexes used in a host of industrial applications and manufacturing processes.

We acquired seven patents for the FEP in January 2004 and built a pilot production facility in Idaho that began operation in 2006.  In 2010, we were granted an additional process patent on FEP based upon information gained through the operation of the pilot facility.  Our pilot facility was not used for commercial gas production but instead focused upon production of high-purity products and examined methods of scaling up the size of the production operations in support of the proposed de-conversion facility in New Mexico.  By the end of 2012, we had completed our testing of individual components and analytical processes and in April 2013, we shut down the pilot facility and terminated our lease on that property.

In October 2012, we received the Nuclear Regulatory Commission (NRC) construction and operating license for the planned de-conversion facility.  This is a forty (40) year operating license and is the first commercial license of this type issued in the U.S.  There are no other companies with a similar license application under review by the NRC and the license does not require us to begin construction of the project by any specific date.  Therefore, the NRC license represents a significant competitive barrier and we believe that it provides us with a very valuable asset now and in the future when we are ready to resume formal design and engineering work on the plant.

3

Due to changes in the nuclear industry near the end of 2013, we placed further engineering work on the proposed uranium de-conversion facility on hold. We still anticipate a potential future need for a depleted uranium conversion facility and, therefore, we are keeping all licenses and permits current.

Further activity within this segment will be deferred until market and industry conditions change and justify resuming design and construction of the facility.  In the meantime, we expect to continue to incur some costs associated with the maintenance of licenses, property agreements, and other project investments.

In connection with the proposed de-conversion facility, Lea County, New Mexico transferred property to us under the provisions of the New Mexico Local Economic Development Act, Project Participation Agreement (PPA) as a location for construction of the facility.  Under the original agreement, we were obligated to meet certain performance objectives.  We did not meet these objectives, however, in July 2015, we executed an amendment to the PPA that extended the due date of the Phase I construction to December 31, 2016, and Phase I completion and hiring at least 75 employees to December 31, 2016.  We did not meet the December 31, 2016 deadline and management is working with Lea County to execute an additional modification to the agreement to further extend these dates once an estimated resumption date has been identified. If we do not succeed in extending the commitment dates or in reaching performance dates set forth in a modified agreement then we may either purchase or re-convey the property to Lea County, New Mexico.  In addition, if Lea County does not agree to that modification and we do not retain title to the property, it could have a material adverse impact on our planned de-conversion and FEP project since another location would need to be selected and evaluated for environmental compliance.

Industry Overview, Target Markets, and Competition

The industries and markets that require or involve the use of radioactive material are diverse.  Our current core business operations involve products that are used in a wide variety of applications and in various markets.  The following provides an explanation of the markets and competitive factors affecting our current business segments.

Nuclear Medicine Standards

Cobalt Products

Historically, we sold high-activity bulk cobalt to one customer that used it to fabricate several models of sealed sources for medical and industrial applications.  In June 2012, a leak of a cobalt target at the ATR belonging to another commercial business resulted in the curtailment of all further cobalt handling and production activities at the ATR pending completion of several corrective actions.  Due to this issue, we were forced to discontinue the irradiation of that cobalt target design.  Aside from a few shipments in 2014 and 2016 we have not been able to process this old material. We believe that this older material will be recoverable from the targets and once we are able to ship the material to our facility, we can make this determination.  Through collaboration with the DOE, we have determined a viable and cost-effective method of transporting this material to our facility and anticipate shipments to begin about third quarter 2019.

Additionally, we were able to purchase bulk cobalt from another supplier during 2018 and were able to manufacture some sealed source products during 2018. We anticipate that we will continue to use this alternate cobalt supply in 2019.

In 2014, we entered into a new 10-year agreement with the DOE utilizing a new cobalt target design.  Because of the lengthy irradiation time required we initially anticipated that cobalt shipments to customers would resume in late 2018. However, due to irradiation delays at the ATR, we now expect those shipments to take place during the third quarter of 2019. Our cobalt products are used in applications such as radiation therapy, security devices, radiography examination and in some commercial applications.  While there are other technologies available to provide external radiation therapy, there are several new devices just gaining market approval that still depend on cobalt sources for their specialized applications.  There are currently no other producers of high specific activity cobalt in the U.S., however, there is one producer of medium specific activity material and there are at least three significant producers

4

of high specific activity material in Canada and other parts of the world.  In addition to us, there is only one other company in the U.S. currently licensed to handle large quantities of cobalt.

We manufacture cobalt sources as well as recycle used cobalt sources by recovering the cobalt for re-use in the manufacture of new sealed sources for teletherapy devices, irradiators, and other source applications.  We are the only company in the U.S. that provides this unique service.   There has been a significant increase in regulation by the NRC in recent years that has created a significant barrier to new entrants to this market.  We expect steady demand for cobalt sealed source products over the next several years but are currently dependent upon our contract relationship with the DOE for access to its ATR in Idaho for a large portion of our cobalt production activities. The interruption to cobalt production experienced in 2012 had a significant negative impact on our cobalt products business segment, and although we currently have a ten-year irradiation contract in place with the DOE, future interruptions in the operation of the ATR could have a negative impact on our cobalt products business segment.  With our new cobalt production contract in place with the DOE we anticipate our market position in this business segment will become stronger in future years.

Radiochemical Products

We typically supply radiochemical products in bulk form. The markets for most radiochemicals are highly competitive.  The target markets for these products are customers who (1) incorporate them into finished industrial or medical devices; (2) use radioisotope products in clinical trials for various medical applications; or (3) further process and include the radioisotope products into pharmaceutical products approved by the U.S. FDA for labeled use in therapy or imaging.

We have submitted an aNDA to the FDA for a radiochemical sodium iodide product. The FDA has granted the Company’s request for an expedited review of the application which could accelerate the approval of the product. Once approved we anticipate a quick start-up of commercial sales of the drug product which should have a significant positive impact on our revenues. We are also considering other generic drug opportunities and plan to expand the range of products offered within this business segment in the coming years.

Fluorine Products and the Planned Depleted Uranium De-Conversion Facility

Our Fluorine Products segment was developed in conjunction with uranium de-conversion in order to take advantage of the anticipated need for depleted uranium de-conversion services.  Our FEP patents provide a unique opportunity to provide certain high-purity fluoride compounds while also offering a “for fee” de-conversion service to the uranium enrichment industry.  During 2013, we curtailed the formal engineering work on the de-conversion facility because of a lack of demand for uranium de-conversion services at that time.  However, we believe that in the future there will be a demand for this service to address still growing stockpiles of depleted UF6.   When that demand occurs, we believe the ground-work we have completed on the depleted uranium de-conversion and fluorine extraction project should put us in a strong position to take advantage of our position in the industry and should serve to justify the financial investment in this uranium de-conversion project in the future.

Radiological Services

Our radiological services include the support of field services, including therapy unit decommissioning, and gemstone processing.

In the past several years, we have seen increased opportunities for radiological field service activities involving installation or decommissioning of radiation devices in hospitals, research institutions, and various other commercial facilities. In 2012, we obtained our first amendment to our NRC license to permit certain field service activities and since that time radiological field service work has become a significant contributor to revenue within the segment.  During 2018 and 2017 we were awarded numerous contracts for field service activities in connection with the DOE’s OSRP program as well as contracts through the IAEA.  We designed and built a mobile hot cell unit for use in this field service work and in 2014 and 2015 we were granted additional amendments to our NRC license that have allowed us to expand the types of services we can provide. The design of our mobile hot cell allows us to adapt it to work in various source removal situations that would not otherwise be possible.  We will continue to use the mobile hot cell to support these expanded services both domestically and internationally. While there are other companies that compete with us for field services work, we believe our mobile hot cell gives us a unique competitive advantage in some of these opportunities. We are under contract for several of these jobs which are scheduled to take place in 2019. We will continue to pursue these field service opportunities in the U.S. and abroad and expect that, in future years, field services will be the major source of revenue within this business segment.

Our transportation services (IITS) was originally formed as a separate business segment to support transportation of our own products and to provide “for hire” transportation services.  Over the years the business activities in this segment were primarily derived from the Company’s radiological services and cobalt products business segments.  Therefore, beginning in the first period of 2018, we began combining the transportation services financial reporting within the radiological services segment to provide more qualitative reporting. Prior period information has been adjusted for comparative reporting.

Government Regulation

Licensing

We currently operate under two NRC licenses, one for broad scope operations and another for exempt distribution. Our broad scope license covers calibration and reference standard manufacturing and distribution, radioisotope processing and distribution, large scale cobalt processing and recycle operations, radioactive gemstone processing, environmental sample analysis, certain field service activities, and research and development.  The exempt distribution license permits the release and distribution of irradiated gemstones to unlicensed entities in the U.S.  All of our existing licenses and permits are adequate to allow current business operations.  We do not handle “special nuclear materials” (i.e. nuclear fuels and weapons grade uranium, thorium or plutonium); therefore, our facility is not designated as a “nuclear” facility that would require additional licensing.

As a condition of our NRC licenses in Idaho, we are required to provide financial assurance for decommissioning activities.  We fulfill this license requirement with a surety bond which names the NRC as beneficiary and is supported by a restricted cash account held in trust by a third party. In January 2018, we re-evaluated the financial assurance needed to support decommissioning and increased the bond amount and the restricted cash amount during the first quarter of 2018. Similar financial assurances will be required to fund the decommissioning of the proposed de-conversion facility.

In October 2012, we were granted a 40-year construction and operating license by the NRC for our planned depleted uranium de-conversion and fluorine extraction processing facility (the “de-conversion facility”).  The de-conversion facility is planned to be located in Lea County, New Mexico, and is proposed to initially de-convert up to approximately 11 million pounds of depleted uranium hexafluoride (DUF₆) annually into fluoride products and depleted uranium oxides (DUO).  Further engineering work on the proposed de-conversion facility was placed on hold in 2013 until additional contracts for utilization could be obtained.  There is no specific timeline required by the NRC for the start of construction on this project. The majority of the pre-construction design, licensing and state permitting has already been completed for the project and a ground water permit from the state of New Mexico remains to be obtained before the plant could begin operation.

Regulation of Radioisotope Production Waste

All of our manufacturing processes generate some radioactive waste.  We must handle this waste pursuant to the Low Level Radioactive Waste (LLRW) Policy Act (LLRW Act), which requires the safe disposal of mildly radioactive materials.   The estimated costs for storage and disposal of these materials have been included in the manufacturing and sales price of our products.  However, actual disposal costs are subject to change at the discretion of the disposal site and are ultimately applied at the time of disposal.  We have obtained all necessary permits and approvals for the disposal of our waste materials and we do not anticipate any negative changes in capacity or regulatory conditions that would limit or restrict our waste disposal capabilities.

The planned de-conversion facility will produce large quantities of depleted uranium oxide waste.  Disposal of depleted uranium waste will be the responsibility of the customers suppling DUF6 to the company for de-conversion.  There are proposed changes to some of the regulations for low level radioactive waste disposal that could impact the rules surrounding disposal of large quantities of depleted uranium.  The Company will continue to monitor any changes in the regulatory framework that could impact the de-conversion facility project.

Nuclear Regulatory Commission Oversight

We operate under two NRC licenses and are subject to NRC oversight and periodic inspections of our operations.

Other Regulations

We are registered as a medical device manufacturer through the FDA for several of our nuclear medicine reference and calibration standards. We are registered with the U.S. Department of Transportation (DOT) for the shipment of radioactive materials. We also have an NRC license for the import and export of radioactive materials.  Because of increasing security controls and regulations, it is likely that we may encounter additional regulations affecting transportation, storage, sale, and import/export of radioactive materials.

We are also subject to inspection by the FDA to be in compliance with cGMP for our sodium iodide product and are registered with the FDA as an Active Pharmaceutical Ingredient manufacturer and a manufacturing facility.  We have submitted an aNDA to the FDA for our sodium iodide product. Once approved, the facility will thereafter be subject to periodic and random inspections by the FDA for the continued manufacture of this drug product.

6

We are subject to government regulation and intervention both in the U.S. and in all foreign jurisdictions in which we conduct business. Compliance with applicable laws and regulations results in higher capital expenditures and operating costs and changes to current regulations with which we must comply can necessitate further capital expenditures and increases in operating costs to enable continued compliance.

Environmental Compliance

We are subject to various federal, state, local and foreign government requirements regulating the discharge of materials into the environment or otherwise relating to the protection of the environment. These laws and regulations include, but are not limited to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the Resource Conservation and Recovery Act (RCRA) and state statutes such as the Idaho Hazardous Waste Management Act, the LLRW Policy Act, NRC regulations concerning various irradiated, radioactive, and depleted uranium materials, and U.S. DOT regulations concerning shipment of radioactive materials. Certain of these laws and regulations can impose substantial fines and criminal sanctions for violations and require installation of costly equipment or operational changes to limit emissions and/or decrease the likelihood of accidental hazardous substance releases. We have incurred, and expect to continue to incur, capital and operating costs to comply with these laws and regulations. For the years ended December 31, 2018 and 2017, we incurred costs of approximately $153,000 and $307,000, respectively, for licensing and monitoring fees. In addition, changes in laws, regulations and enforcement of policies, or the imposition of new clean-up requirements or remedial techniques, could require us to incur costs in the future that would have a negative effect on our financial condition or results of operations.

Distribution Methods for Products

We sell our products directly to our customers who, in some cases, are both end users and distributors.  We use common commercial carriers and our own transportation vehicles and personnel for delivery of our products.  For smaller quantities of material, and overnight and next-day delivery, we utilize other commercial carriers.  For our products that involve large quantities of radioactive material, most commonly cobalt-60, and that invoke certain special transportation requirements, we use our own specially trained employees.

Dependence on Customers

Historically, we have been dependent on one customer, RadQual, of which we own 24.5%, for a significant amount of our gross revenue.  In August 2017, several affiliates of the Company purchased the remaining 75.5% and at that time, we were named as a managing member of RadQual.  Our sales to RadQual prior to August 2017 accounted for approximately 17% of our total gross revenue for 2017 and our sales to RadQual for 2018 totaled approximately 24% of our total gross revenue.

Combined sales, on which we are dependent, to our three largest customers, accounted for 46% of our total gross revenues in 2018 and accounted for 31% of our total gross revenues in 2017. We are making efforts to reduce our dependency on a small number of customers by expanding sales in both domestic and foreign markets and through our relationship with our joint venture, TI Services, to expand distribution of our nuclear medicine products.  The change in ownership of RadQual and naming us as a managing member of RadQual business operations, has significantly reduced any risk associated with RadQual as a single major customer of ours.

In 2004, we obtained certain patents related to the FEP.   In 2010, we were granted an additional process patent on the FEP process and during 2011 we started the process to file for international protections of this patent in South Africa, Russia, and the European Union.  During 2012, we were granted additional process patents for the FEP process in the United States.  In 2013, the FEP process patent was granted in Russia and in 2014 the FEP process patent was granted in South Africa.

Employees

As of December 31, 2018, we had 32 total employees, including 30 full-time employees.

Item 1A.

RISK FACTORS

Readers should carefully consider the following factors that may affect our business, future operating results and financial condition, as well as other information included in this Annual Report. The risks and uncertainties described below are not the only ones the Company faces. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our business operations. If any of the following risks actually occur, our business, financial condition and operating results could be materially adversely affected.

Risks Related To Our Company Generally

We have incurred, and may continue to incur, losses.   We have incurred net losses for most fiscal periods since our inception. From inception through December 31, 2018, we have generated $115,017,303 in revenues and an accumulated deficit (including preferred stock dividends and returns) in the amount of $126,541,421. The negative cash flow we have sustained has materially reduced our working capital, which in turn could materially and negatively impact our ability to fund future operations and continue to operate as a going concern. Management has taken and continues to take, actions to improve our financial condition and results of operations. The availability of necessary working capital, however, is subject to many factors beyond our control, including, among other things, our ability to obtain financing on favorable terms, or at all,  economic cycles, market acceptance of our products, competitors' responses to our products, the intensity of competition in our markets, and the level of demand for our products.

We may need additional financing to continue operations.  Because we may continue to experience negative cash flow, we may need to obtain additional financing to continue operations. Management will continue to plan and take actions to improve our financial results which could enhance our ability to obtain debt financing.  However, obtaining additional financing is subject to many factors beyond our control and may not be available to us on acceptable terms or at all.

Our operations expose us to the risk of material environmental liabilities.   We are subject to potential material liabilities related to the remediation of environmental hazards and to personal injuries or property damages that may be caused by hazardous substance releases and exposures. The materials used in our operations expose us to risks of environmental contamination that could subject us to liability, including remediation obligations that could be very costly. In addition, the discovery of previously unknown contamination could require us to incur costs in the future that would have a negative effect on our financial condition or results of operations. We have a Surety Bond in place supported by funds in a restricted cash account to provide the financial assurance required by the NRC for our Idaho facility license for decommissioning and a similar mechanism will be required to fund the decommissioning of the proposed new depleted uranium facility. However, if a contamination event occurred within, or outside of, our facility, we would be financially responsible to remediate such contamination and could have to borrow money or fund the remediation liability from our future revenue. We may not be able to borrow the funds, or have available revenue, sufficient to meet this potential liability, which could have a significant negative impact on our financial condition and results of operations.

We are dependent upon key personnel.   Our ongoing operations are dependent on Steve T. Laflin, President and Chief Executive Officer. The loss of Mr. Laflin could have a material adverse effect on our business. We have a $2 million key man life insurance policy on Mr. Laflin and an employment agreement that extends through February 28, 2022. However, there is no assurance that we will be able to retain Mr. Laflin or our existing personnel or attract additional qualified employees. The loss of any of our key personnel or an inability to attract additional qualified employees could result in a significant decline in revenue.

General economic conditions in markets in which we do business can impact the demand for our goods and services. Decreased demand for our products and services can have a negative impact on our financial performance and cash flow.   Demand for our products and services, in part, depends on the general economic conditions affecting the countries and industries in which we do business. A downturn in economic conditions in the U.S. or industry that we serve may negatively impact demand for our products and services, in turn negatively impacting our operations and financial results. Further, changes in demand for our products and services can magnify the impact of economic cycles on our businesses. For instance, our topaz gemstone processing is affected by the demand for luxury items such as jewelry as well as by the instability of foreign markets which are key factors in the manufacture of products using irradiated gemstones.

Volatility in raw material and energy costs, interruption in ordinary sources of supply and an inability to recover unanticipated increases in energy and raw material costs from customers could result in lost sales or significantly increase the cost of doing business.   Market and economic conditions affecting the costs of raw materials, utilities, energy costs, and infrastructure required for the delivery of our goods and services are beyond our control and any disruption or halt in supplies, or rapid escalations in costs could affect our ability to manufacture products or to competitively price our products in the marketplace.  For instance, an interruption in the supply of isotopes such as cobalt-57, cobalt-60, or iodine-131 could result in lost sales of nuclear medicine and calibration standards sales, cobalt product sales and radiochemical products.

8

We are subject to extensive government regulation in jurisdictions around the globe in which we do business. Regulations address, among other things, environmental compliance, import/export restrictions, healthcare services, taxes and financial reporting, and can significantly increase the cost of doing business, which in turn can negatively impact our operations, financial results and cash flow.   We are subject to government regulation and intervention both in the United States and in all foreign jurisdictions in which we conduct business. Compliance with applicable laws and regulations results in higher capital expenditures and operating costs and changes to current regulations with which we must comply can necessitate further capital expenditures and increases in operating costs to enable continued compliance. Additionally, from time to time, we may be involved in legal or administrative proceedings under certain of these laws and regulations. Significant areas of regulation and intervention include the following:

Radioactive Waste.   All of our manufacturing processes generate some radioactive waste. For waste that cannot be decayed in storage we must handle this waste pursuant to the LLRW Policy Act, which requires the safe disposal of mildly radioactive materials. The estimated costs for storage and disposal of these materials have been included in the manufacturing and sales price of our products. However, actual disposal costs are subject to change at the discretion of the disposal site and are ultimately applied at the time of disposal. An unexpected or material increase in these costs could have a material adverse effect on our financial condition and results of operations.

Health Compliance.   Health regulations dictated by the United States Occupational Safety and Health Administration and NRC are extensive in our business. There is no assurance that our activities will comply with all applicable health regulations at times and, as a result, may expose us to liability under applicable health regulations. Costs and expenses resulting from such liability may materially negatively impact our operations and financial condition. Overall, health laws and regulations will continue to affect our business worldwide.

NRC License Enforcement Actions.   The NRC may take enforcement action in the event that we are found to be in violation of NRC regulations or in violation of any of our license requirements.  Consequences of violations depend upon the severity of the violations as well as the adequacy and timeliness of corrective actions implemented by the licensee to investigate and correct the cause of the violation and to prevent reoccurrence.  The NRC has discretionary authority in the action they choose to take against license violations, but these actions can include civil penalties and restrictions upon licensee operations or license suspension. The imposition of any such penalties and/or restrictions upon our operations or suspension of our license could have a material adverse effect on our financial condition and results of operations.

Environmental Regulation.   We are subject to various federal, state, local and foreign government requirements regulating the discharge of materials into the environment or otherwise relating to the protection of the environment. These laws and regulations include, but are not limited to CERCLA, the RCRA and state statutes such as the Idaho Hazardous Waste Management Act, the LLRW Policy Act, NRC regulations concerning various irradiated, radioactive, and depleted uranium materials, and U.S. DOT regulations concerning shipment of radioactive materials. Certain of these laws and regulations can impose substantial fines and criminal sanctions for violations and require installation of costly equipment or operational changes to limit emissions and/or decrease the likelihood of accidental hazardous substance releases. We have incurred, and expect to continue to incur, capital and operating costs to comply with these laws and regulations. In addition, changes in laws, regulations and enforcement of policies, or the imposition of new clean-up requirements or remedial techniques, could require us to incur costs in the future that would have a negative effect on our financial condition or results of operations.

Import/Export Regulation.   We are subject to significant regulatory oversight of our import and export operations due to the nature of our product offerings. Penalties for non-compliance can be significant and violations can result in adverse publicity. Because of increasing security controls and regulations, it is likely that we may encounter additional regulations affecting the transportation, storage, sale, and import/export of radioactive materials.

Taxes.   We structure our operations to be tax efficient and to make use of tax credits and other incentives. Nevertheless, changes in tax laws, actual results of operations, final audit of tax returns by taxing authorities, and the timing and rate at which tax credits can be utilized can change the rate at which we are taxed, thereby affecting our financial results and cash flow.

We may incur material losses and costs as a result of product liability claims that may be brought against us.  We face an inherent business risk of exposure to product liability claims in the event that products supplied by us fail to perform as expected or such failures result, or are alleged to result, in bodily injury. Although we have purchased insurance with coverage and in amounts that we believe to be adequate and reasonable in light of our current and planned operations, including our planned uranium de-conversion and fluoride gas production business, if a successful product liability claim were brought against us in excess of our available insurance coverage, it would have a material adverse effect on our business and financial results.

9

Our earnings, cash flow and financial position are exposed to financial market risks worldwide, including interest rates.   Fluctuations in domestic and world markets could adversely affect interest rates and impact our ability to obtain credit or attract investors. Such market risk could have a negative impact on future business opportunities including our ability to raise additional capital for planned business expansion.  We also purchase some of our radiochemical products from overseas suppliers and the price of those products could be adversely affected through changes in currency exchange rates.

Catastrophic events such as natural disasters, pandemics, war and acts of terrorism could disrupt our business or the business of our suppliers or customers, and any such disruptions could have a negative impact on our operations, financial results and cash flow.   Our operations are at all times subject to the occurrence of catastrophic events outside our control, ranging from severe weather conditions such as hurricanes, floods, earthquakes and storms, to health epidemics and pandemics, to acts of war and terrorism. Any such event could cause a serious business disruption that could affect our ability to produce and distribute our products and possibly expose us to third-party liability claims. Additionally, such events could impact our suppliers, thereby causing energy and raw materials to become unavailable to us, and our customers, who may be unable to purchase or accept our products and services. Any such occurrence could have a negative impact on our operations and financial condition.

Our future growth is largely dependent upon our ability to develop new products that achieve market acceptance with acceptable margins.   Our businesses operate in global markets that are characterized by rapidly changing technologies and evolving industry standards. Accordingly, our future growth rate depends upon a number of factors, including, but not limited to, our ability to (i) identify emerging technological trends in our target end-markets, (ii) develop and maintain competitive products, (iii) enhance our products by adding innovative features that differentiate our products from those of our competitors, and (iv) develop, manufacture, and bring products to market quickly and cost-effectively. Our ability to develop new products based on technological innovation or U.S. FDA approval can affect our competitive position and requires the investment of significant resources. These development efforts divert resources from other potential investments in our businesses, and they may not lead to the development of new products on a timely basis or that meet the needs of our customers as fully as competitive offerings. In addition, the markets for our products may not develop or grow as we currently anticipate. The failure of our technologies or products to gain market acceptance due to more attractive offerings by our competitors could significantly reduce our revenues and adversely affect our competitive standing and prospects.

Risks Related To Our Current Business Operations

We are dependent on various third parties in connection with our business operations.   The production of high-specific activity cobalt is dependent upon the DOE, and its prime-operating contractor, which controls the Idaho reactor. Current activity at the Idaho ATR may continue to affect the supply of cobalt material needed for the manufacture of cobalt sources.  Loss of the ability to use, or cost-effectively use, these irradiation services would significantly impact our cobalt products business segment because there is not currently another reactor available in the U.S. that is capable of providing this type of service for us. Our radiochemical iodine is supplied to us through three supply sources. Unanticipated contract terminations by any of these suppliers and other third parties would have a material adverse impact on our operations, financial results, and cash flow.

We are dependent on a limited number of customers in connection with our current business operations.  During 2018 and 2017, sales to RadQual represented 24% and 17%, respectively, of our total gross revenue. Combined sales to our three top customers accounted for 46% and 31% of our total gross revenue during 2018 and 2017, respectively. Although we are making efforts to reduce our dependency on a small number of customers, the loss of any one of these customers could have a significant impact on our future results of operations and financial condition. Unanticipated contract terminations by any of these current customers could have a material adverse impact on operations, financial results, and cash flow.

We are subject to competition from other companies.   Each of our existing business areas has direct competition from other businesses. High-specific activity cobalt is supplied by other reactor facilities around the world. Nuclear medicine calibration and reference standards are being produced by one other major manufacturer in the U.S. Most of our radiochemicals are also manufactured by several other companies in the world, and there are other providers of radiological field services. Most of our competitors have significantly greater financial resources that could give them a competitive advantage over us.

Risks Related To Our Common Stock

Trading in our common stock is limited and the price of our common stock may be subject to substantial volatility.  Our common stock is quoted on the OTCQB Marketplace under the U.S. trading symbol “INIS”. The market for our securities is limited, the price of our stock is volatile, and the risk to investors in our common stock is greater than the risk associated with stock trading on other markets. These factors may reduce the potential market for our common stock by reducing the number of potential investors. This may make it more difficult for investors in our common stock to sell shares to third parties or to otherwise dispose of their shares. This could cause our stock price to decline.

10

We currently do not intend to pay dividends on our common stock.  We do not plan to pay dividends on shares of our common stock in the near future. Consequently, an investor in our common stock can only achieve a return on its investment in us if the market price of our common stock appreciates.

We are contractually obligated to issue shares in the future, which will dilute your interest in us.  As of December 31, 2018, there were approximately 19,541,000 shares of common stock issuable upon the exercise of vested stock options, at a weighted-average exercise price of $.05 per share.  An additional 33,972,216 shares were reserved for issuance under our equity plans as of December 31, 2018. Our outstanding preferred stock and certain of our outstanding debt is also convertible into shares of our common stock at the holders’ option.  In addition, we expect to issue additional options to purchase shares of our common stock to compensate employees, consultants and directors, and we may issue additional shares to raise capital to expand our manufacturing capability, develop additional products, or fund our planned uranium de-conversion plant.  Any such issuances will have the effect of further diluting the interest of the holders of our securities.  Also, outstanding as of December 31, 2018, were Series M Warrants for the issuance of 17,165,000 shares of common stock and Series N Warrants for the issuance of 2,925,000 shares of common stock. The weighted average exercise price for all outstanding warrants as of December 31, 2018 was $0.12 per share.

Risks Related to Our Proposed De-Conversion and FEP Produced Fluoride Gas Business

We will need to raise additional funds to complete the construction of our de-conversion and FEP facility.  We need to secure more customer contracts and raise additional funds to complete the design and construction of a de-conversion facility with a production-scale FEP operation. We may not be able to raise the additional capital required to complete the facility on acceptable terms, or at all.  In addition, the total funds required to complete this project have been based upon early preliminary estimates and, while we believe these estimates are conservative, unforeseen expenses may be incurred and additional funding may be required to complete the project.

We do not have an operating history with respect to our strategy to combine de-conversion services and FEP-produced fluoride gas products and this business may not succeed.   We have no operating results with respect to providing de-conversion services or producing high volumes of fluoride gas products using FEP to date and, therefore, we do not have an operating history upon which you can evaluate this business or our prospects. Our prospects must be considered in light of the risks and uncertainties encountered in entering a new line of business.

Some of these risks relate to our potential inability to:

• construct our planned de-conversion and FEP production plant, including the effective management of the cost of the design and construction of the facility, and obtain the additional financing necessary for such construction;

•  maintain the necessary regulatory approvals for the facility and the ongoing operations of the facility;

•  obtain the groundwater permit from the state of New Mexico;

•  produce commercially economic volumes of high-purity fluoride products using FEP;

•  effectively manage this new business and its operations;

•  successfully establish and maintain our intended low-cost structure; and

•  successfully address the other risks described throughout this Annual Report.

If we cannot successfully manage these risks, our business and results of FEP operations and financial condition will suffer.

There is no history of large-scale commercial fluoride gas production utilizing FEP.  We have successfully demonstrated the feasibility of using FEP to produce some fluoride gases and Starmet Corporation (Starmet), which originally developed and patented the technology, also used FEP to produce a fluoride gas. However, FEP has not been used for large-scale commercial production of the size and magnitude envisioned in conjunction with the de-conversion process and there may be technical issues and process challenges related to the utilization of FEP for large-scale commercial production. Unforeseen issues associated with constructing and scaling up these new FEP operations could significantly impact our proposed schedule and our overall ability to produce high-purity fluoride gas in the quantities anticipated.

11

Prior to the start of operations of the facility, we must obtain a Ground Water Permit from the State of New Mexico, and we cannot guarantee the amount of time required to obtain this permit from the State of New Mexico for operation of these facilities.   The operation of the planned depleted uranium de-conversion facility requires a ground water permit from the State of New Mexico.  There is no assurance that the ground water permit will be issued to us by the State of New Mexico.  We also have no control over the actual time required by the State of New Mexico to review and approve the application for the ground water permit.  Failure to obtain the permit, or any delay in obtaining the permit, could delay the start of operations of our planned depleted uranium de-conversion facility, thereby delaying revenue-generating operations at the facility.

The DOE is obligated to take depleted uranium from enrichment companies.   The DOE has constructed two depleted uranium de-conversion facilities. These facilities are obligated to process depleted uranium produced from United States commercial uranium enrichment facilities at a price determined by DOE. We believe our depleted uranium processing facility will offer the better value to enrichment companies, but we cannot assure you that enrichment companies will not select the DOE as their de-conversion service provider.

We may be handling large quantities of DUF₆ and fluoride products, which are radioactive and hazardous materials, respectively, and are subject to intense regulation.  The hazardous nature of DUF₆ and fluoride products affects the actions we are required to take for licensing, air permitting, environmental review, emergency response, liability insurance, personnel training, and generally increases the level of concern by the general public with respect to our handling of these materials. All of these factors complicate the licensing and operations processes and involve a host of additional regulatory factors that could affect the timeline for completing our de-conversion and FEP facility.  Additionally, the NRC is revising its regulations on the disposal of depleted uranium waste at LLRW disposal facilities that accept large quantities of depleted uranium. Any changes to the current regulations may result in increased disposal costs that we intend to pass through to our customers, which, depending on the significance of the increased cost, may cause potential customers to continue to store their DUF ₆ rather than pay for de-conversion and disposal services.

We will be subject to competition from the DOE and other companies.   While there are no currently operating commercial DUF₆ de-conversion facilities in the U.S., the DOE is operating two de-conversion plants intended to process DUF₆ from the DOE’s existing 1.5 billion-pound stockpile.  Additionally, AREVA currently operates a de-conversion plant in France, UUSA is constructing a facility in the U.K., and the State Atomic Energy Corporation ROSATOM has constructed a facility in Russia. We cannot assure you that the operators of the existing DUF ₆ de-conversion facilities will not build additional facilities to expand their operations and compete with us in providing de-conversion services or that commercial enrichment companies will not choose to ship their depleted DUF ₆ overseas for processing in France, the U.K., or Russia.

Our business may be harmed if we fail to protect our proprietary FEP technology utilized in our planned de-conversion and FEP production facility.   We rely on patents to protect our intellectual property rights to the FEP technology to be used in our planned de-conversion and FEP production plant. Although we have filed international Patent Cooperation Treaty (PCT)  applications to seek international protection for the FEP process in certain countries, we cannot be certain that our competitors will not be able to design around our patents and that the laws of some countries in which our FEP patents are or may be practiced will protect our products or intellectual property rights to the same extent as do the laws of the United States, increasing the possibility of piracy of our patents. Although we intend to vigorously defend our intellectual property rights, we may not be able to prevent misappropriation of our FEP technology. Our competitors may also independently develop technologies that are substantially equivalent or superior to our technology.

Item 2.

PROPERTIES

We lease one property which serves as or main corporate headquarters and houses all of our current manufacturing operations for our core business segments. We also hold the conditional title to 640 acres of land in Lea County, New Mexico for the proposed de-conversion facility.  The following paragraphs provide a brief summary of these properties.

4137 Commerce Circle, Idaho Falls, Idaho – The facility located on this property houses our main corporate headquarters and all of our current manufacturing operations. We hold this property pursuant to a lease that extends through April 2021.  The facility was new when leased in March 2001 and remains in excellent condition.  We have a purchase option and a right of first refusal on this property that allows us to purchase this property at any time for a stated amount.

Land - Lea County, New Mexico – In August 2011, we received land from Lea County, New Mexico, pursuant to a PPA, whereby the land was deeded to us for no monetary consideration. In return, we committed to construct a uranium de-conversion and FEP facility on the land.  In order to retain title to the property, we were 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. We did not meet the performance milestones set forth in the PPA and we executed a modification to the agreement extending these due dates to December 31, 2016 and 2017, respectively, but did not meet either of those milestones and are working again with Lea County to further extend the commitment dates.  If we do not succeed in extending the commitment dates or in reaching performance dates set forth in a modified agreement then we may, at our 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.  We have 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 our obligations under the agreements for permanent transfer of the title.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of our results of operations and financial condition should be read in conjunction with the accompanying financial statements and related notes thereto included in Item 8, “Financial Statements and Supplementary Data,” within this Annual Report. Some of the information contained in this discussion and analysis or set forth elsewhere in this Annual Report, including information with respect to our plans and strategies for our business, statements regarding the industry outlook, our expectations regarding the future performance of our business and the other non‑historical statements contained herein are forward‑looking statements. See “Cautionary Note Regarding Forward‑Looking Statements.” You should also review the “Risk Factors” in Item 1A. of this Annual Report for a discussion of important factors that could cause actual results to differ materially from the results described herein or implied by such forward‑looking statements.

Overview

We manufacture a full range of nuclear medicine calibration and reference standards, a wide range of products including cobalt teletherapy sources, and a varied selection of radioisotopes and radiochemicals for medical research, pharmacy compounding, and clinical applications. We also provide a host of transportation, recycling, and processing services on a contract basis for customers. A more detailed description of each of these product lines and services along with a description of our business segments can be found in Item 1, “Business” within this Annual Report.

During 2018, we focused our efforts on achieving profitability in each of our core business segments and reached several significant goals.  During 2018, we:

·

Increased revenue by approximately 40% and reduced our net loss by approximately 78%;

·

Pursued and were awarded numerous field service jobs through the DOE’s OSRP and other domestic programs using our mobile hot cell and highly experienced personnel and increased revenue in the Radiological Services segment by approximately 67%;

·

Contracted with an alternate supplier of cobalt-60 to fulfill cobalt contract obligations and meet customer demand for various types of sealed source products, which increased our revenue in the Cobalt products segment by approximately 302%;

·

Expanded sales of our nuclear medicine products through exercising our management opportunity with RadQual.  In particular, we increased our international sales by utilizing the marketing and distribution expertise of our joint venture with TI Services;

·

Supported the review and approval by the U.S. FDA of our request for an expedited review of our aNDA, which could accelerate the approval of the product; and

·

Maintained our relationships in Lea County, New Mexico (location of our proposed de-conversion facility), through business meetings and correspondence with Lea County officials, and continued to pursue opportunities to obtain additional contracts for depleted uranium de-conversion services related to our proposed de-conversion project.

Business Strategy and Core Philosophies

Broadly defined, our business strategy is to continue to build our reputation as a leader in the cobalt, radiochemical, field services, and nuclear medicine product industries, as well as seek ways to improve our customer service and expand our market share, with the ultimate goal of providing greater return to our shareholders.  Specifically, we are continuously working with our customers to improve and develop products to better serve the needs of the end user which, ultimately, we believe will boost product sales. A key part of our short-term and long-term business strategy is to develop and market additional generic drug products, such as our sodium iodide product, in our core business segments that will offer customers a high quality and desirable product as well as increase our revenues and secure additional customer contracts. In addition, we will pursue financial support that will be structured in such a way to support further expansion of our products and services.

Our core philosophy is to strive to provide high quality products and services as a profitable and environmentally conscious business, while offering excellent customer service and providing a safe and high-quality working environment for our employees.  We operate in accordance with an ISO Quality Management System and in accordance with all current Good Manufacturing Practices under which we seek to maintain the highest level of quality and continuously improve our product manufacturing processes.

Following is a summary of results of operations for 2018:

·

Revenue in 2018 was approximately $10.4 million, which is a 40% increase over 2017;

·

Our 2018 sales in our Cobalt Products, Nuclear Medicine Products, and Radiological Services business segments all increased as compared to 2017;

·

Our 2018 sales in Radiochemical Products declined as compared to 2017;

·

Our total gross profit rate increased from 44% in 2017 to 45% in 2018; and

·

Our operating costs for 2018 decreased approximately 6% as compared to operating costs for 2017.

Year Ended December 31, 2018 Compared to Year Ended December 31, 2017

The following table presents comparative revenues for the years ended December 31, 2018 and 2017:

Revenues

Radiochemical Products

Sales of radiochemical products accounted for approximately 21% of our total sales revenue in 2018 and approximately 31% of total sales revenue in 2017. Sales in this segment decreased by $57,725, or approximately 2% to $2,264,007 as compared to $2,321,732 in 2017. This decrease in revenue was the result of an interruption in our supply of sodium iodide material when one of our suppliers shut-down its operations for an extended period.  We were able to acquire material from an alternate supplier but experienced a delay in receiving material for customer orders. Because we were able to identify alternate suppliers of sodium iodide during 2018, we so not anticipate supply interruptions during 2019.

Within this segment, we currently distribute sodium iodide (I-131) as a radiochemical product. This product is being used for a variety of applications including use in investigational and clinical trials for the treatment of breast, lung, prostate, and ovarian cancers. We have submitted an aNDA to the FDA for a sodium iodide radiopharmaceutical product which was accepted for an expedited review by the FDA.  This is the first of several potential generic drug products we plan to submit to the FDA in the coming years. We believe that the product enhancements we have made, in addition to the generic drug products we plan to submit to the FDA, should increase future sales in this business segment.

15

Cobalt Products

Cobalt products sales accounted for approximately 20% of our total sales revenue in 2018 and approximately 7% in 2017.  Sales in this segment increased by $1,533,675, or approximately 302%, in 2018 to $2,041,579, as compared to $507,904 in 2017. The increase was the result of our ability to purchase bulk cobalt-60 from an alternate supplier in order to fill outstanding customer orders and is discussed in more detail below. Our sealed source manufacturing generates the majority of our revenue within this segment and sealed source sales depend on our ability to produce or procure this cobalt material.

Although we have not been able to obtain high specific activity material from the ATR reactor since late 2013, periodically we are able to acquire recycled material that can be used to manufacture sealed sources for customers, and in some instances, our customers have supplied their own cobalt material for source fabrication. In October 2014, we entered into a ten-year agreement with the DOE for the irradiation of cobalt targets.  It takes approximately three to five years to irradiate these cobalt targets to the desired level of activity and we anticipated having high specific activity cobalt available for our customers in late 2018.   However, extended reactor shut-downs delayed this delivery schedule and we now expect to have high specific activity cobalt available for customers by about the third quarter of 2019, and every year thereafter, through at least 2024.  The agreement gives us the ability to purchase the current full capacity of the DOE’s ATR throughout the ten-year period.

In March 2017, we completed a purchase agreement for some additional cobalt material from a supplier and that material was delivered to us in late 2017 and early 2018.  The limited availability of cobalt material during most of 2017 directly impacted our ability to manufacture high activity sealed sources in this business segment, however, with the receipt of the material from our alternate supplier, we were able to resume fulfilling customer orders and significantly increased sales in this business segment during 2018. As mentioned above, in late 2018 we expected to receive material currently undergoing irradiation at the ATR.  However, extended periods of shut-down of the ATR delayed this delivery schedule and we now expect to receive shipments in the third quarter of 2019.  Delivery of this high specific activity material should support strong cobalt product sales in late 2019 and beyond.

In 2015, 2016, and 2018, we entered into cobalt supply agreements with several customers.  Pursuant to these contracts, we will supply bulk cobalt-60 and, in some cases, provide source manufacturing and installation services for the customer. The terms of these cobalt contracts require some advance   progress payments from each customer. The funding received under these contracts has been recorded as unearned revenue under short- and long-term liabilities in our consolidated financial statements. We began recognizing some of this revenue in 2018 when we fulfilled contract performance objectives by supplying sealed sources manufactured with cobalt from our alternate supplier.

As of December 2018, we continued to hold many old design cobalt targets at the ATR that have undergone some irradiation. In 2018, in performing year-end analytical procedures, we concluded that the older design targets we hold at the ATR, and that we continue to report as inventory, hold varying but significant market values in excess of their current carrying values and we concluded that no impairment existed. We anticipate that during the third quarter of 2019, when we expect to begin shipping the new design targets to our facility, we will begin shipping these older design targets to our facility as well. We will extract the material from these older targets and determine its value to us in manufacturing sources. We will periodically continue to review any residual value of this cobalt material for potential impairment and make adjustments to the carrying value if deemed appropriate.

Nuclear Medicine Standards

Sales of nuclear medicine standards accounted for approximately 37% and 44%, of our total sales revenue in 2018 and 2017, respectively. Sales in this segment increased by $556,550, or approximately 17%, to $3,788,779 in 2018, as compared to $3,232,229 in 2017.

In August 2017, affiliates of the Company purchased 75.5% of the member units of RadQual and at that time, we were named as one of the managing members of RadQual.  Because of this change in member ownership and management, we have consolidated RadQual’s operations within the nuclear medicine segment for financial reporting.  For purposes of consolidation, all significant intercompany activity has been eliminated in the reporting process. Prior to this change in control, we reported our 24.5% interest in RadQual using the equity method of accounting.

We formed a 50/50 joint venture, TI Services, with RadQual in 2010, to distribute products and promote services for nuclear medicine, nuclear cardiology and PET imaging. Again, due to our affiliate members and management, we have also consolidated TI Services into our financial statements and have eliminated all intercompany transactions.

As a result of the change to consolidated reporting, revenue in this segment includes all of our 2018 sales to RadQual and to TI Services, our 50/50 joint venture with RadQual, with all intercompany sales eliminated.  In 2017, revenue in this segment includes all sales to RadQual and TI Services prior to August 10, 2017, with non-controlling interest income eliminated for TI Services, and all sales of RadQual and TI Services from August 10, 2017 to December 31, 2017 with intercompany sales for this consolidated period eliminated.

16

We anticipate that our sales through RadQual will remain strong and that the change in RadQual member ownership and management will create significant future opportunities to work on new product development and customer service improvements. Additionally, we will continue to work closely with TI Services using their expertise in marketing and distribution strategies to strengthen nuclear medicine product sales through TI Services.

Radiological Services

The following table presents radiological services revenue for the years ended December 31, 2018 and 2017:

Revenues from our Radiological Services segment accounted for approximately 22% of our total sales revenue in 2018 and approximately 18% in 2017. Sales in this segment increased by $915,933, or approximately 67%, from $1,385,525 in 2017, to $2,274,458 in 2018.  The increase in revenue is attributable to numerous radiological field service contracts awarded to us under the DOE’s OSRP and through the IAEA.

Revenue from field service work performed in connection with both the DOE’s OSRP and the IAEA accounts for the majority of revenue in this segment and was $1,897,952 for the year ended December 31, 2018, and $976,262 for the same period in 2017.  This is an increase of $921,690, or approximately 94%, and was the result of the increased number of these contracts were awarded to us by the DOE. In addition, we have numerous field service jobs under contract with the DOE that we expect to complete during 2019.

Revenue from gemstone processing for the year ended December 31, 2018, was $376,506 compared to $382,263 for the same period in 2017.  This was a slight decrease of $5,757, or approximately 2%. This slight decrease in revenue from gemstone processing is the combined result of the quantity of stones being held on our premises awaiting shipment requests from our customer, as well as fluctuations in the current market demand for luxury items such as jewelry. We expect similar fluctuations to occur in future periods.

Radiological Field Services accounted for approximately 83% of the Radiological Services segment sales in 2018 and approximately 72% in 2017.  Gemstone processing accounted for approximately 17% of Radiological Services sales in 2018 and approximately 28% in 2017.

Fluorine Products

There was no revenue to report from the Fluorine Products segment for 2018.  We developed our fluorine products in conjunction with the uranium de-conversion project, in order to take advantage of the anticipated need for depleted uranium de-conversion services. We established the Fluorine Products segment in 2004 to support production and sale of the gases produced using our FEP. Our FEP patents offer a unique opportunity to provide certain high-purity fluoride compounds while also offering a “for fee” de-conversion service to the uranium enrichment industry. From 2004 to 2012, we used a pilot facility to develop production processes for various high-purity products and to test methods of scaling up the size of FEP production in support of a planned de-conversion facility in Lea County, New Mexico.  In 2012, we completed our testing of individual components and analytical processes and late in 2013 we closed the pilot plant facility. Also, in 2013, we made the decision to place continued formal design work on the proposed de-conversion facility on hold until such time that we are able to secure additional de-conversion services contracts. Until such time that work resumes on the project, we will 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.

During 2018, we incurred $122,651 of planning and other expenses related to the de-conversion project, as compared to $209,110 in 2017.  This is a decrease of $86,459, or approximately 41%, and is the result of decreased consulting and interest costs allocated to this project in 2018. We expect that our costs in the future will be limited to essential items such as continued interactions with our customers, the state of New Mexico, and Lea County, New Mexico.

We are no longer reporting transportation activities in a separate business segment. In the past, the business activities previously reported in this segment were primarily derived from our radiological services and cobalt products business segments.  Because of this, beginning in 2018, we began combining transportation services financial activities within these other segments to provide more qualitative reporting. Prior period results for the affected segments have been retrospectively revised to reflect this change.

17

Cost of Revenues and Gross Profit

During 2018, we continued to monitor and control direct costs.  Raw materials used in our radiochemical products, nuclear medicine standards, and our cobalt products segments represent the bulk of direct costs for 2018.  In each of these business segments, we have purchase agreements in place with suppliers to obtain optimum pricing. Periodically, the cost increases for these raw materials or we may also use alternate supply sources for our material which might not carry pricing as favorable as our contracted suppliers. Specifically, in our cobalt products segment, we contracted with a supplier for cobalt-60 material used in source production which increased our direct costs in that business segment.  We have turned to alternate suppliers for this material until we are able to obtain cobalt from the targets currently undergoing irradiation at the DOE’s ATR.

Throughout 2018, in our nuclear medicine product segment, we maintained a low cost of scrapped material as a result of adjustments made in the manufacturing processes in this segment.  With the exception of the cost of cobalt material, we are not aware of any significant future price increases that may potentially affect our cost of revenues.

Operating Costs and Expenses

Total operating costs and expenses for 2018 were $4,980,357, as compared to $5,303,258 in 2017.  This is a decrease of $322,901, or approximately 6%.

The following table presents operating costs and expenses for 2018 as compared to 2017:

Salaries and contract labor expense increased by $193,453, or approximately 9%, which is the result of annual salary and wage increases and periodic performance awards made during the year as well as the addition of new personnel. In addition, non-cash equity compensation expense recorded for the year ended December 31, 2018 was $188,476 as compared to $163,873 for the same period in 2017.  This is an increase of $24,603, or approximately 15%, and is the result of equity compensation recorded for outstanding stock options granted to employees and non-employees.

General administrative and consulting expenses decreased to $2,200,044 in 2018, as compared to $2,808,303 in 2017, a decrease of $608,259, or approximately 22%. This significant decrease is due to the conclusion of arbitration proceedings and the related decrease in legal costs which concluded in December 2017.  Additionally, our licensing costs decreased during the year ended December 31, 2018 as compared to the same period in 2017, as a result of certain facility licensing fees incurred in 2017 but not incurred in 2018.

18

Research and development expense was $468,603 for 2018, compared to $376,698 for 2017.  This is an increase of $91,905, or approximately 24%. The majority of this increase in research and development expense is the result of increased costs associated with development work being done in our Radiochemical Products segment, specifically, increased costs pertaining to support work for the submittal and monitoring of the abbreviated new drug application to the FDA.  During both 2018 and 2017 we limited further investment in the planned de-conversion facility and limited further spending on the project only for expenses necessary to maintain licensing and continued interactions with New Mexico and Lea County. We will continue to delay further engineering work on the de-conversion project until we are able to secure additional contracts for de-conversion services.

Other Income (Expense)

The following table presents other income (expense) for 2018 as compared to 2017:

Other income was $86,796 for 2018 as compared to other expense of $1,203,234 for 2017. For the year ended December 31, 2017, we recorded a loss on the forfeit of an asset, discussed above, in the amount of $255,000.  This amount represented the cash deposit on the AOS shipping container that we recorded as an asset on our consolidated balance sheets. When we were informed after arbitration proceedings that we would not recover the deposit, we recorded the $255,000 loss as other expense.

Also, in August 2017, affiliates of the Company, including our Chairman of the Board and Chief Executive Officer, acquired a 75.5% interest in RadQual.  Prior to this ownership change, we reported our investment in RadQual as an asset on our consolidated balance sheets in the amount of $1,436,843. At August 10, 2017, the fair market value of our investment in RadQual was determined to be $489,999 and we recorded a loss of $946,844 as other expense for the year ended December 31, 2017, to adjust the carrying value to fair value.

Interest income in 2018 was $9,428 as compared to $3,051 in 2017.  This increase of $6,377 was due to interest earned on increased cash balances held at banks and other institutions in interest-bearing accounts.

Interest expense decreased during 2018, to $470,106, from $509,740 in 2017. This is a decrease of $39,634, or approximately 8%. This decrease in interest expense is the combined result of a decrease in interest paid on our Notes (as defined below), which carried an interest rate of 8% per year prior to their maturity and repayment in full in July 2017 and an increase in dividends recorded as interest, paid on Series C Preferred Stock that was issued in 2017 and for which the first annual interest payment was made in 2018. The majority of interest expense recorded in 2017 was related to the Notes.  Interest expense recorded for the Notes was $294,382 for the year ended December 31, 2017, whereas no interest was recorded for the Notes in 2018 as a result of the July 2017 repayment at maturity. In addition, dividends accrued on Series C Preferred Stock, which was issued as a result of the amended notes, totaled $215,358 and was recorded as interest expense for 2017. Dividends accrued on Series C Preferred Stock totaled $257,002 and were recorded as interest expense for 2018.

In connection with the 2013 Promissory Note (as defined below), we recorded $30,000 of interest expense for each of 2018 and 2017, and approximately $27,000 of non-cash interest expense related to a debt discount feature on the 2013 Promissory Note for 2018 and 2017.

In September 2016, we borrowed an aggregate of $360,000 from our Chairman of the Board and one of our directors (the “2016 Promissory Note”). The 2016 Promissory Note bears interest at 6% per annum, which was payable upon maturity on March 31, 2017 and was secured by all unencumbered assets.  Per the terms of the 2016 Promissory Note, at any time, the lenders could settle any or all of the principal and accrued interest with shares of our common stock, or our other securities, based on the average closing price of our common stock over a 20-day period. In February 2017, all principal plus accrued interest under the 2016 Promissory Note was converted into shares of our Series C Preferred Stock and warrants that we offered through a private placement transaction, as described herein.

Net Loss

Our net loss was $844,576 in 2018, compared to a net loss of $3,757,284 in 2017. This is a decrease in loss of $2,912,708, or approximately 78%. Our decrease in net loss is the result of our approximate 40% increase in revenue, the approximate 4% decrease in operating expense and the approximate 77% decrease in other expense, all of which are discussed above.

19

Liquidity and Capital Resources

On December 31, 2018, we had cash and cash equivalents of $828,039 compared to $409,338 at December 31, 2017. Net cash provided by operating activities was $97,159 in 2018, compared to net cash used in operating activities of $465,744 in 2017.  This represents a decrease in cash used in operating activities of approximately $563,000.

Accounts receivable at December 31, 2018 were $820,370 as compared to $635,026 at December 31, 2017. Historically, we have not written off any accounts receivable, and there were no accounts written off during 2018.

Inventories at December 31, 2018 were $2,765,729 as compared to $1,951,513 at December 31, 2017.  The majority of our inventory consists of irradiated material held at the site of the DOE’s prime-operating contractor, which controls the ATR located outside of Idaho Falls, Idaho.  For 2018, our target inventory accounted for approximately 89% of our work in process inventory and includes cobalt targets of an older design as well as irradiated cobalt material under a new contract with the DOE. During 2017, our target inventory accounted for approximately 92% of our work in process inventory. In 2018 and 2017, as part of our year-end procedures, we evaluated our older target inventory for impairment and concluded that these older design targets have varying but significant degrees of market value depending on any additional costs we may have to incur to transport them to our facility for processing.

Included in our raw material inventory are raw cobalt, strontium and other raw elements. During 2017 we wrote-off approximately $1,500 to expense for raw material we believed to be of no future value to us. We had no similar write-down in 2018. Raw material inventory is regularly reviewed for obsolescence.

Included in our work in process inventory are in-process and completed nuclear medicine products, irradiated cobalt and nuclear medicine-related materials and products.

We incurred a net loss of $844,576, for the year ended December 31, 2018, and have an accumulated deficit of $126,541,421 since inception.  To date, our operations and plant and equipment expenditures have been funded principally from proceeds from public and private sales of debt and equity as well as through asset sales.

Net cash used in investing activities was $86,320 for 2018 and net cash provided by investing activities for 2017 was $80,180.  During 2018, we used $86,320 to purchase equipment.  During 2017, we used $110,115 to purchase property and equipment and intangible assets, acquired cash through consolidation accounting of RadQual of $81,184, and received member distributions from our investment in RadQual in the amount of $109,111.

In July 2012, we entered into a securities purchase agreement with certain institutional and private investors pursuant to which we sold convertible, unsecured debentures for an aggregate of $3,069,900 (the Notes). The Notes carried an interest rate of 8% and had were scheduled to mature in July 2017.  The Notes were convertible at any time into shares of our common stock at an initial conversion price of $0.225 per share, subject to adjustment under certain conditions.  Each investor also received a common stock purchase warrant to purchase common stock equal to 25% of the shares issuable upon conversion of the 8% Notes.  These warrants were immediately exercisable at a price of $0.30 per share and had a term of five years.

In February 2017, we entered into subscription agreements with certain investors, including two of our directors, for the sale of (i) an aggregate of 3,433 shares of Series C Preferred Stock, and (ii) Class M warrants to purchase an aggregate of 17,165,000 shares of our common stock (Class M Warrants), for gross proceeds of $3,433,000. The Series C Preferred Stock accrues dividends at a rate of 6% per annum, payable annually on February 17th of each year, commencing on February 17, 2018.  Shares of Series C Preferred Stock are convertible at the option of the holder at any time into shares of our common stock at an initial conversion price equal to $0.10 per share, subject to adjustment.  At any time after February 17, 2019, if the volume-weighted average closing price of our common stock over a period of 90 consecutive trading days is greater than $0.25 per share, we may redeem all or any portion of the outstanding Series C Preferred Stock at the original purchase price per share plus any accrued and unpaid dividends, payable in shares of common stock.  All outstanding shares of Series C Preferred Stock must be redeemed by us on February 17, 2022 at the original purchase price per share, payable in cash or shares of common stock, at the option of the holder. Holders of Series C Preferred Stock do not have any voting rights, except as required by law and in connection with certain events as set forth in the Statement of Designation of the Series C Preferred Stock. The Class M Warrants are immediately exercisable at an exercise price of $0.12 per share, subject to adjustment as set forth in the warrant, and have a term of five years.

20

In March 2017, we amended the Notes and gave the noteholders certain additional rights (the Amendment).  Pursuant to the Amendment, the Notes were modified to provide each holder the right, at the holder’s option and exercisable prior to May 12, 2017, to convert all or any portion of the principal amount of the Notes, plus accrued but unpaid interest, into shares of our Series C Preferred Stock at a conversion price of $1,000 per share.  Holders that elected to convert their Notes into Series C Preferred Stock received a warrant to purchase up to 3,750 shares of our common stock for each share of Series C Preferred Stock received upon conversion of the Notes, with each warrant having a five-year term, a cashless exercise feature, and an exercise price of $0.10 per share of common stock. As a result of this modification, an aggregate of $780,000 of the Notes was converted to 780 shares of Series C Preferred Stock and 2,925,000 Class N Warrants.  Residual interest was also paid to Note holders who converted was $1,515. The Notes matured in July 2017 and were repaid in full.

In December 2013, we entered into a promissory note agreement with our chairman of the Board and one of our major shareholders pursuant to which we borrowed $500,000. The $500,000 note bears interest at 6% and was originally due June 30, 2014.  At any time, the lenders may settle any or all of the principal and accrued interest with shares of the Company’s common stock.  In connection with the note, each of the two lenders was issued 5,000,000 warrants to purchase shares of the Company’s common stock at a purchase price of $0.06 per share.  In June 2014, we renegotiated the terms of this promissory note. Pursuant to the modification, the maturity date was extended to December 31, 2017, and each Lender was granted an additional 7,500,000 warrants to purchase shares of the Company’s common stock at $0.06 per share.  The warrants were immediately exercisable.  In December 2016, the note was modified to extend the maturity date to December 31, 2022, with all remaining terms remaining unchanged. On December 23, 2018, all of the warrants expired.

In March 2016, we entered into a note payable for the purchase of a vehicle.  The principal amount financed was $47,513.  The term of the note is six years and the note carries an interest rate of 6.66%.  Monthly payments are $805 and the note matures April 2022. The note is secured by the vehicle.

In August 2017, we entered into a promissory note agreement with our Chairman of the Board, pursuant to which we borrowed $60,000 (the “2017 Promissory Note”). The 2017 Promissory Note bears interest at 5% per annum and was scheduled to mature on June 30, 2018 and was unsecured. On February 12, 2019, the maturity date was extended to July 31, 2019. At December 31, 2018, accrued interest on the 2017 Promissory Note totaled $4,117.

In April 2018, we borrowed $120,000 from our Chief Executive Officer and Chairman of the Board pursuant to a short-term promissory note (the “2018 Promissory Note”). The 2018 Promissory Note accrues interest at 6% per annum, which is payable upon maturity of the 2018 Promissory Note. The 2018 Promissory Note is unsecured and originally matured on August 1, 2018. At any time, the holder of the 2018 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. Pursuant to an amendment to the 2018 Promissory Note on June 29, 2018, the maturity date was extended to March 31, 2019 with all other provisions remaining unchanged. Pursuant to a second amendment to the 2018 Promissory Note on February 12, 2019, the maturity date was extended to July 31, 2019. At December 31, 2018, accrued interest on the 2018 Promissory Note totaled $5,220.

In February 2019, we borrowed $185,474 from RadQual pursuant to a short-term promissory note with a stated interest rate of 6% and a maturity date of July 31, 2019. The promissory note is unsecured.

We expect that cash from operations, cash obtained through securities offerings, and our current cash balance will be sufficient to fund operations for the next twelve months. Although we may seek additional debt financing for our projects and operations in the future, there is no assurance that we will be able to secure additional debt financing on acceptable terms to us, or at all.

Off-Balance Sheet Arrangements

As of December 31, 2018, we had no material off-balance sheet arrangements or obligations.

Goals for 2019

Based upon the investments we have made in our facilities and investments we anticipate making, and based on projects, and products developed in 2018, we have the following goals for 2019:

·

Support the review and approval of our abbreviated new drug application by the U.S. FDA for our sodium iodide product;

·

Pursue additional field service work through both the DOE’s OSRP program and other domestic and international programs utilizing our mobile hot cell and highly experienced personnel;

21

·

Begin production development of one or more new generic drug products to further enhance revenue production within our Radiochemical segment and identify additional future generic product opportunities;

·

Expand sales of our nuclear medicine products and increase cash flow by using our management opportunity with RadQual to expand international sales and utilize the marketing expertise of our joint venture, TI Services;

·

Continue to expand our customer base, increase revenues, reduce production and operating costs, and attempt to achieve profitability in our core business segment operations; and

·

Continue to support essential tasks related to our de-conversion project and continue to pursue any opportunities to obtain additional contracts for depleted uranium de-conversion.

Critical Accounting Policies

Revenue recognition - We recognize revenue when products ship or services are performed according to predetermined amounts per customer contract obligations or milestones. We have contracted with several customers for the purchase of cobalt-60 material which is currently undergoing irradiation. We have collected advance payments from these customers for project management and up-front handling and irradiation charges and these prepayments have been recorded as unearned revenue. Our estimated future recognition of this unearned revenue is based on an irradiation completion and shipment schedule and on product shipment dates and service performance dates.

Patents and other intangibles - We amortize our patents and intangibles using the straight-line method over their estimated useful lives.  Patents and other intangibles are evaluated for impairment annually or when events or circumstances arise that indicate the existence of impairment. We evaluate the recoverability of intangible assets whenever events or changes in circumstances indicate that an intangible asset’s carrying amount may not be recoverable. Such circumstances could include, but are not limited to, (1) a significant decrease in the market value of an asset, (2) a significant adverse change in the extent or manner in which an asset is used, or (3) an accumulation of costs significantly in excess of the amount originally expected for the acquisition of an asset. If impairment indicators exist, we measure the carrying amount of the asset against the estimated undiscounted future cash flows associated with it. Should the sum of the expected future cash flows be less than the carrying value of the asset being evaluated, an impairment loss would be recognized. The impairment loss would be calculated as the amount by which the carrying value of the asset exceeds its fair value.

Impairment of long-lived assets - As part of our year-end procedures we test our long-lived assets for signs of impairment when indicators of impairment exist. If impairment indicators exist, we measure the carrying value of the asset against its estimated future cash flows.  If the expected future value is less than the carrying value of the asset an impairment loss would be recognized.

Critical Accounting Estimates

Asset retirement obligation – The asset retirement obligation is based on the expected future cash flows of the decommissioning funding plan.   The decommissioning funding plan is based on the estimated number of hours of specific personnel, estimated wages and disposal costs.  Once the decommissioning funding plan has been developed, we use a discount rate to determine the estimated current value of the liability.

New Accounting Standards

In May 2014, the FASB issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes all existing revenue recognition requirements, including most industry specific guidance. The new standard requires a company to recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration that the company expects to receive for those goods or services. The FASB has subsequently issued the following amendments to ASU 2014-09 which have the same effective date and transition date of January 1, 2018:

·

In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which delayed the effective date of the new standard from January 1, 2017 to January 1, 2018. The FASB also agreed to allow entities to choose to adopt the standard as of the original effective date.

·

In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations, which clarifies the implementation guidance on principal versus agent considerations.

22

·

In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which clarifies certain aspects of identifying performance obligations and licensing implementation guidance.

·

In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients related to disclosures of remaining performance obligations, as well as other amendments to guidance on collectability, non-cash consideration and the presentation of sales and other similar taxes collected from customers.

In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, which amends certain narrow aspects of the guidance issued in ASU 2014-09 including guidance related to the disclosure of remaining performance obligations and prior-period performance obligations, as well as other amendments to the guidance on loan guarantee fees, contract costs, refund liabilities, advertising costs and the clarification of certain examples.

We have evaluated and implemented this guidance, particularly as it pertains to the Company’s cobalt products segment where pre-payments are received from customers and has determined that this guidance will not have a material impact on its consolidated financial statements. We maintain the practice of identifying performance obligations under customer contracts and recognizes revenue only as contractual milestones are met and in an amount that is in accordance with the contract price allocated to that performance obligation. Unearned revenue and pre-payments on contracts are recorded as either short-term or long-term liability on our consolidated balance sheets with revenue recognized in the period in which we fulfill the performance obligation.

In February 2016, the FASB issued ASU 2016-02, “Leases” which was issued to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements.  The amendments in ASU 2016-02 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.  We have completed our assessment and will record significant asset and liability balances in connection with our leased property. We expect to record an adjustment of approximately $800,000 in January 2019, to both the assets and liabilities to recognize a lease related to real estate.

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows” which was issued to improve uniformity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments in ASU 2016-15 were effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years.  We adopted this guidance effective January 1, 2018, and it did not have any impact on the Company’s consolidated statements of cash flows.

We adopted ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force)” (“ASU 2016-18”), effective January 1, 2018. This update clarified that transfers between cash and restricted cash are not reported as cash flow activities in the statements of cash flows. As such, restricted cash amounts are included with cash and cash equivalents in the beginning-of-period and end-of-period total amounts on the statements of cash flows. We applied this update retrospectively, which resulted in an adjustment to the beginning-of-period and end-of-period total amounts on the condensed consolidated statement of cash flows for the year ended December 31, 2017 to include restricted cash balances from those periods.

In June 2018, the FASB issued ASU 2018-07, “Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting”, which expands the scope of Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 specifies that Topic 718 applies to all share-based payment transactions in which the grantor acquires goods and services to be used or consumed in its own operations by issuing share-based payment awards. ASU 2018-07 also clarifies that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under ASC 606. The amendments in ASU 2018-07 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We have assessed this topic and have concluded that there will be no impact of this guidance on our consolidated financial statements.

Report of Independent Registered Public Accounting Firm

To the Board of Directors
International Isotopes, Inc. and Subsidiaries
Idaho Falls, Idaho

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of International Isotopes, Inc. and Subsidiaries as of December 31, 2017 and 2016, and the related consolidated statements of operations, stockholders’ equity, and cash flows, for the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the International Isotopes, Inc. and Subsidiaries as of December 31, 2017 and 2016, and the results of their operations and their cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the entity’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to International Isotopes, Inc. and Subsidiaries in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. International Isotopes, Inc. and Subsidiaries is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risk of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks.  Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements.  Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.  We believe that our audits provide a reasonable basis for our opinion.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEARS ENDED DECEMBER 31, 2018 AND 2017

NOTE 1 – DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Description of business – International Isotopes Inc. (the “Company” or “INIS”) was incorporated in Texas in November 1995. The accompanying 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 the Company and its wholly-owned subsidiaries, International Isotopes Idaho Inc., International Isotopes Fluorine Products, Inc., and International Isotopes Transportation Services, Inc. The consolidated financial statements also include the accounts of TI Services, LLC, (“TI Services”), and the accounts of RadQual, LLC (RadQual).  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 devices, and is headquartered in Idaho Falls, Idaho.  In addition, the Company owns a 24.5% interest in RadQual. In August 2017, affiliates of the Company purchased 75.5% of RadQual and at the time the Company was named as one of the two managing members of RadQual. As a result of this ownership change, the Company has significant influence in management decisions with regard to RadQual’s business operations.

Nature of Operations – INIS and its subsidiaries, TI Services and RadQual (collectively, the “Company,” “we,” “our” or “us”) manufacture a full range of nuclear medicine calibration and reference standards, a wide range of products, including cobalt teletherapy sources, and a varied selection of radioisotopes and radiochemicals for medical research, pharmacy compounding, and clinical applications.  The Company also distributes a varied selection of radioisotopes and radiochemicals for medical and clinical research applications. The Company also provides a host of transportation, recycling, and radiological field services on a contract basis for customers and holds several patents for a fluorine extraction process that it plans to use in conjunction with a proposed commercial depleted uranium de-conversion facility which would be located in Lea County, New Mexico (the “De-Conversion Facility”). The Company’s business consists of five business segments: Nuclear Medicine Standards, Cobalt Products, Radiochemical Products, Fluorine Products, and Radiological Services Beginning in 2018, the Company began reporting the Transportation segment activity, which was previously reported as a separate segment, within its other business segments. 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 the operating cycle, have been recorded as unearned revenue and, depending upon estimated ship dates, classified under either current or long-term liabilities on the Company’s consolidated balance sheets.  These unearned revenues will be recognized as revenue in the future period during which the cobalt shipments begin.  All assets expected to be realized in cash or sold during the normal operating cycle of the business are classified as current assets.

Principles of Consolidation – The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, as well as its 24.5% interest in RadQual, and its 50% owned joint venture, TI Services.

Because the Company controls a greater than 50% direct and indirect ownership interest in TI Services, the operating results and financial condition of TI Services, are consolidated with those of the Company.  In addition, because the Company has significant management control over RadQual’s operations, all of RadQual’s operating results and financial condition are consolidated with those of the Company. All significant intercompany accounts and transactions have been eliminated during consolidation.

Significant accounting policies

a)

Financial instruments and cash equivalents

The carrying value of notes payable approximates fair value because they bear interest at rates which approximate market rates.

Cash and cash equivalents, totaling $828,039 and $409,338 at December 31, 2018 and 2017, respectively, consist of operating accounts and money market accounts. For purposes of the consolidated statements of cash flows, the Company considers all highly-liquid financial instruments with original maturities of three months or less at date of purchase to be cash equivalents.

F-7

At December 31, 2018 and 2017, the Company had pledged cash on deposit in a money market account valued at $622,428 and $453,575, respectively, as security for a surety bond.  The surety bond is required as part of the Company’s operating license agreement with the Nuclear Regulatory Commission (NRC).

In addition, at December 31, 2017, the Company reported restricted cash in the amount of $387,455 which represented a cash contingency held by RadQual as a result of the sale of membership units in RadQual in August 2017. The purchasing members of RadQual stipulated that a cash contingency be created to cover expenses and other debt incurred by the prior managing member of RadQual.  This determination was concluded in 2018 and the remaining cash was distributed to the prior member.  At December 31, 2018, there was no restricted cash held by RadQual.

The Company maintains its cash accounts in various deposit accounts, the balances of which are periodically in excess of federally insured limits.

b)

Accounts receivable

The Company sells products mainly to recurring customers, wherein the customer’s ability to pay has previously been evaluated. The Company generally does not require collateral. The Company periodically reviews accounts receivable for amounts considered uncollectible and allowances are provided for uncollectible accounts when deemed necessary. At December 31, 2018 and 2017, the Company recorded no allowance for uncollectible accounts.

c)

Inventories

Inventories are carried at the lower of cost or net realizable value. Cost is determined using the first in, first out method. Work in progress inventory contains product that is undergoing irradiation and this irradiation process can take up to three years to reach high specific activity (HSA) levels. When indicators of inventory impairment exist, the Company measures the carrying value of the inventory against its market value, and if the carrying value exceeds the market value, the inventory value is adjusted down accordingly.  For the years ended December 31, 2018 and 2017, no cobalt inventory impairment was recorded. During 2017, $1,500 of raw material inventory was determined to be obsolete and was written off to expense.

d)

Property, plant and equipment

Depreciation on property, plant and equipment is computed using the straight-line method over the estimated useful life of the asset.

Leasehold improvements are amortized over the shorter of the life of the lease or the service life of the improvements. Maintenance, repairs, and renewals that neither materially add to the value of the property nor appreciably prolong its life are charged to expense as incurred. Gains or losses on dispositions of property and equipment are included in the results of operations.

e)

Goodwill and other intangibles

Goodwill is not amortized but is tested for impairment at least annually. Goodwill represents the excess of the purchase price over the fair value of net tangible and identifiable intangible assets recorded as a result of the change in ownership for each of RadQual and TI Services.  As of December 31, 2018, there had been no impairment of goodwill.

Patents and other intangibles are amortized using the straight-line method over their estimated useful lives and are evaluated for impairment at least annually or when events or circumstances arise that indicate the existence of impairment. The Company evaluates the recoverability of identifiable intangible assets whenever events or changes in circumstances indicate that an intangible asset’s carrying amount may not be recoverable. Such circumstances could include but are not limited to: (1) a significant decrease in the market value of an asset, (2) a significant adverse change in the extent or manner in which an asset is used, or (3) an accumulation of costs significantly in excess of the amount originally expected for the acquisition of an asset. When indicators of impairment exist, the Company measures the carrying amount of the asset against the estimated undiscounted future cash flows associated with it. Should the sum of the expected future cash flows be less than the carrying value of the asset being evaluated, an impairment loss would be recognized. The impairment loss would be calculated as the amount by which the carrying value of the asset exceeds its fair value. The evaluation of asset impairment requires the Company to make assumptions about future cash flows over the life of the asset being evaluated. These assumptions require significant judgment and actual results may differ from assumed and estimated amounts. During the years ended December 31, 2018 and 2017, the Company had no impairment losses related to intangible assets.

F-8

f)

Impairment of long-lived assets

Long-lived assets are reviewed for impairment annually, or when events or circumstances arise that indicate the existence of impairment, using the same evaluation process as described above for patents and other intangibles.  There was no impairment recorded during the years ended December 31, 2018 and 2017.

g)

Income taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rate is recognized in income in the period that includes the enactment date.

h)

Use of estimates

Company management has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of revenues and expenses during the reporting period to prepare these consolidated financial statements in conformity with GAAP.  Actual results could differ from those estimates.

i)

Revenue recognition

Revenue is recognized when products are shipped. No warranty coverage or right of return provisions are provided to customers. Amounts received as prepayment on future products or services are recorded as unearned revenues and recognized as income when the product is shipped or service performed.

j)

Research and development costs

Research and development costs are expensed as incurred and totaled $468,603 and $376,698 for the years ended December 31, 2018 and 2017, respectively. These research and development costs were incurred to maintain our planned de-conversion facility license and in our radiochemical products and nuclear medicine standards business segments.

k)

Share-based compensation

The Company accounts for issuances of share-based compensation to employees in accordance with GAAP which requires the recognition of the cost of employee services received in exchange for an award of equity instruments in the financial statements and is measured based on the grant date fair value of the award. Compensation expense is recognized over the period during which an employee is required to provide service in exchange for the award (the vesting period).

For the years ended December 31, 2018 and 2017, the Company recognized share-based compensation expense of $188,476 and $163,873, respectively, related to stock options, warrants and stock grants. This expense is included as part of salaries and contract labor in the accompanying statements of operations.

l)

Net loss per common share – basic and diluted

Basic loss per share is computed on the basis of the weighted-average number of common shares outstanding during the year. Diluted loss per share is computed on the basis of the weighted-average number of common shares plus all potentially dilutive issuable common shares outstanding during the year.

At December 31, 2018 and 2017, the Company had the following common stock equivalents outstanding that were not included in the computation of diluted net loss per common share as their effect would have been anti-dilutive, thereby decreasing the net loss per common share:

F-9

m)

Business segments and related information

GAAP establishes standards for the way public business enterprises are to report information about operating segments in annual financial statements and requires enterprises to report selected information about operating segments in interim financial reports issued to shareholders. It also establishes standards for related disclosure about products and services, geographic areas and major customers. The Company currently operates in five business segments.

n)

Recent accounting standards

In May 2014, the FASB issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes all existing revenue recognition requirements, including most industry specific guidance. The new standard requires a company to recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration that the company expects to receive for those goods or services. The Company has evaluated and implemented this guidance which had no material effect on the financial statements.

The FASB has subsequently issued the following amendments to ASU 2014-09 which have the same effective date and transition date of January 1, 2018:

·

In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which delayed the effective date of the new standard from January 1, 2017 to January 1, 2018. The FASB also agreed to allow entities to choose to adopt the standard as of the original effective date.

·

In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations, which clarifies the implementation guidance on principal versus agent considerations.

·

In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which clarifies certain aspects of identifying performance obligations and licensing implementation guidance.

·

In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients related to disclosures of remaining performance obligations, as well as other amendments to guidance on collectability, non-cash consideration and the presentation of sales and other similar taxes collected from customers.

·

In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, which amends certain narrow aspects of the guidance issued in ASU 2014-09 including guidance related to the disclosure of remaining performance obligations and prior-period performance obligations, as well as other amendments to the guidance on loan guarantee fees, contract costs, refund liabilities, advertising costs and the clarification of certain examples.

The Company has evaluated this guidance, particularly as it pertains to the Company’s cobalt products segment where pre-payments are received from customers and has determined that this guidance will not have a material impact on its consolidated financial statements. The company maintains the practice of identifying performance obligations under customer contracts and recognizes revenue only as contractual milestones are met and in an amount that is in accordance with the contract price allocated to that performance obligation. Unearned revenue and pre-payments on contracts are recorded as either short-term or long-term liability on the Company’s consolidated balance sheets with revenue recognized in the future period in which the Company fulfills the performance obligation.

F-10

In February 2016, the FASB issued ASU 2016-02, “Leases” which was issued to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements.  The amendments in ASU 2016-02 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.  We are in the process of completing our assessment and anticipate that ASU 2016-02 will have a material impact on our consolidated Balance Sheets, as we will record significant asset and liability balances in connection with our leased property. The Company has evaluated this standard and will record an adjustment of approximately $800,000 in January 2019, to both the assets and liabilities of the Company to recognize a lease related to real estate.

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows” which was issued to improve uniformity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments in ASU 2016-15 were effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years.  The Company adopted this guidance effective January 1, 2018, and it did not have any impact on the Company’s consolidated statements of cash flows.

The Company adopted ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force)” (ASU 2016-18), effective January 1, 2018. This update clarified that transfers between cash and restricted cash are not reported as cash flow activities in the statements of cash flows. As such, restricted cash amounts are included with cash and cash equivalents in the beginning-of-period and end-of-period total amounts on the statements of cash flows. The Company applied this update retrospectively, which resulted in an adjustment to the beginning-of-period and end-of-period total amounts on the condensed consolidated statement of cash flows for the year ended December 31, 2017 to include restricted cash balances from those periods.

In June 2018, the FASB issued ASU 2018-07, “Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting”, which expands the scope of Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 specifies that Topic 718 applies to all share-based payment transactions in which the grantor acquires goods and services to be used or consumed in its own operations by issuing share-based payment awards. ASU 2018-07 also clarifies that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under ASC 606. The amendments in ASU 2018-07 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently assessing the impact of this guidance on its consolidated financial statements.

o)

Reclassifications

Certain prior year amounts have been reclassified to conform with the current year’s presentation.  Net income was not affected by these reclassifications.

NOTE 2 – BUSINESS CONDITION AND LIQUIDITY

The Company has a history of recurring losses with an accumulated deficit of $126,541,421 at December 31, 2018, and a net loss of $844,576 for the year then ended. The Company’s working capital, which includes inventory that will not be sold for up to three years, has decreased by $681,088 from the prior year. The Company has provided cash flows from operations of $97,159.  During 2018, the Company sought to improve future cash flows from operating activities through execution of new sales agreements, improving operating cost control measures, making improvements in current manufacturing processes, pursuing new service contracts, and developing new products. The Company’s net loss was $844,576 in 2018, compared to a net loss of $3,757,284 in 2017. This is a decrease in net loss of $2,912,708.

As discussed in Note 3, net loss for the year ended December 31, 2017 includes loss related to a change from the equity method of accounting to the consolidation method of accounting for the Company’s interest in RadQual.  The related loss totaled $946,844 in 2017 and was included in other expenses.

Also included in net loss for the year ended December 31, 2017, is the loss of a $255,000 deposit made to Alpha Omega Services (AOS) for a shipping container.  The Company entered into arbitration proceedings in 2016 in an attempt to recover the deposit for the container, plus damages, for a total claim of $1,673,241.  The arbitration was concluded in December 2017 and the Company was notified that it would not recover any damages from AOS. Accordingly, in 2017 the Company recorded a $255,000 loss which was included in other expenses.

F-11

During the year ended December 31, 2018, the Company continued to focus on its long-standing core business segments, which consist of its radiochemical products, cobalt products, nuclear medicine standards, and radiological services segments, and in particular, the pursuit of new business opportunities within those segments.

In October 2014, the Company secured a ten-year cobalt production agreement with the United States Department of Energy (DOE).  The agreement provides the Company with access to the currently available cobalt production positions in the DOE’s Advanced Test Reactor (ATR) located at the Idaho National Laboratory in Idaho Falls, Idaho.  The ATR is the only DOE reactor in the United States (U.S) capable of producing large quantities of high specific activity cobalt.

In addition to the cobalt production agreement with the DOE, the Company entered into supply agreements in 2015 with several customers for the purchase of cobalt-60. Because it takes approximately three to five years to irradiate cobalt targets to the desired level of activity, the shipment of cobalt-60 product to these customers was anticipated to begin in mid to late 2018. However, deliveries have been delayed to about the third quarter of 2019 due to unanticipated shut-downs at the DOE’s ATR located outside of Idaho Falls, Idaho.   Pursuant to these cobalt-60 supply agreements, the Company will not only supply cobalt-60 to the customers but, in some instances, will also provide on-going services with respect to manufacturing and selling cobalt sources. Each contract requires quarterly progress payments to be paid by customers to the Company.

Due to changes in the nuclear industry over the past few years, the Company’s plans for the design and construction of a large-scale uranium de-conversion and fluorine extraction facility were placed on hold.  The Company expects that further activity on this project will remain on hold until the market and industry conditions change to justify resuming design and construction of the facility.  The Company will continue to incur some costs associated with the maintenance of licenses and other necessary project investments for the proposed facility, and the Company expects to continue to keep certain agreements in place to support resumption of project activities at the appropriate time. In July 2015, the Company announced that it executed an amendment to its Project Participation Agreement (PPA) with the Lea County, New Mexico Board of Commissioners. The PPA granted to the Company direct and indirect assistance for locating its proposed depleted UF6 de-conversion facility in Hobbs, New Mexico. The principal component of assistance was the conveyance of approximately 640 acres of land for construction and operation of the proposed facility.  The conveyance of the land was contingent upon the Company commencing construction on Phase 1 of the facility by December 31, 2014 and hiring a certain number of employees by December 31, 2015. Under the amendment to the PPA, the Lea County, New Mexico Board of Commissioners agreed to extend those dates to December 31, 2016 and December 31, 2017, respectively. The Company did not meet the deadlines set forth in the amended PPA, but is currently in discussions with the Lea County, New Mexico Board of Commissioners to further extend the milestone dates once a more definitive date for the resumption of the project is known.  If the Company does not succeed in extending the commitment dates or in reaching performance dates set forth in a modified agreement, then it may, at our 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 holds a Nuclear Regulatory Commission (NRC) construction and operating license for the depleted uranium facility 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 believes that it provides it with a very valuable asset. During the year ended December 31, 2018, the Company incurred costs of approximately $123,000 to maintain licenses and other necessary project investments. During the same period in 2017, the Company incurred costs of approximately $209,000 for planning and development activities on the project.

The Company expects that cash from operations 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.

NOTE 3 – PURCHASED ASSET AND INVESTMENTS

Interest in RadQual, LLC

The Company owns a 24.5% interest in RadQual, with which the Company has an exclusive manufacturing agreement for nuclear medicine products. On August 10, 2017, affiliates of the Company, including the Company’s Chairman of the Board and the Chief Executive Officer, acquired the remaining 75.5% interest in RadQual. As a result of this change in ownership, the Company was named as a managing member of RadQual and gained the ability to exercise significant management control over the operations of RadQual. Because of this increased management ability, and pursuant to GAAP, the Company has consolidated the accounts of RadQual into its financial statements beginning as of August 10, 2017. Prior to August 10, 2017, the Company reported its 24.5% ownership of RadQual as an asset with a balance of $1,436,843 and was using the equity method of accounting for this asset. At August 10, 2017, the fair market value of the Company’s investment in RadQual was determined to be $489,999 and the Company reported as other expense a loss of $946,844 for the year ended December 31, 2017, to adjust the carrying value to fair value under ASC 805. Upon recording the fair value of the assets and liabilities of RadQual, a provisional amount of $386,836 was assigned to intangible assets that were acquired and $1,422,991 was recorded as Goodwill. Goodwill was later adjusted, as allowed by ASC 805, when the fair value of a patent included as part of the purchase was determined to be greater than originally recorded.  Accordingly, the amount of Goodwill was decreased with a corresponding increase in the fair value of the patent.

For the year ended December 31, 2017, member distributions from RadQual received prior August 10, 2017, totaled $109,111 and were recorded as a reduction of the investment in RadQual. During the same period, earnings allocated to the Company from RadQual prior to August 10, 2017, totaled $53,173, and were recorded as equity in net income of affiliate on the Company’s condensed consolidated statements of operations and as a reduction to the investment on the consolidated balance sheets, prior to consolidation.

Acquisition of Interest in TI Services, LLC

In December 2010, the Company together with RadQual, formed a 50% owned joint venture, TI Services, LLC (TI Services). TI Services is engaged in the distribution and selling of products related to the nuclear medicine industry. Because the Company controls more than a 50% direct and indirect ownership interest in TI Services, the assets and liabilities of TI Services are consolidated with those of the Company, and RadQual’s non-controlling interest in TI Services is included in the Company’s financial statements as a non-controlling interest.
