(1)       The Company and Basis of Presentation

International Isotopes Inc. (INIS) was incorporated in Texas in November 1995. The accompanying unaudited condensed consolidated financial statements are presented in conformity with accounting principles generally accepted in the United States of America (GAAP) and include all operations and balances of INIS and its wholly-owned subsidiaries, including International Isotopes Idaho Inc., a Texas corporation; International Isotopes Fluorine Products, Inc., an Idaho corporation; International Isotopes Transportation Services, Inc., an Idaho corporation; RadQual, LLC, a limited liability company (RadQual); RadVent, LLC, a limited liability company; Radnostix, LLC, a limited liability company; and TI Services, LLC, a limited liability company (TI Services). RadQual is a global supplier of molecular imaging quality control and calibration devices, and is based at INIS headquarters in Idaho Falls, Idaho. TI Services is headquartered in Boardman, Ohio and distributes products for nuclear medicine, nuclear cardiology, and Positron Emission Tomography (PET) imaging. INIS, and its wholly-owned subsidiaries are collectively referred to herein as the “Company,” “we,” “our” or “us.”

Nature of Operations – The Company manufactures a full range of nuclear medicine calibration and reference standards, a wide range of products, including cobalt teletherapy sources, and an FDA-approved radiopharmaceutical drug product. The Company also holds several patents for a fluorine extraction process that would be used in conjunction with a proposed commercial depleted uranium de-conversion facility which would be located in Lea County, New Mexico (the “De-Conversion Facility”). For 2025, the Company’s business consists of five major business segments: Theranostics Products, Cobalt Products, Nuclear Medicine Standards, Medical Devices, and Fluorine Products. The Company’s headquarters and all operations, with the exception of TI Services, are located in Idaho Falls, Idaho.

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

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

Interim Financial Information – The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (SEC). Accordingly, the accompanying unaudited condensed consolidated financial statements do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments and reclassifications considered necessary in order to make the financial statements not misleading and for a fair and comparable presentation have been included and are of a normal recurring nature. Operating results for the three and six months ended June 30, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025 or any future periods. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on March 3, 2025.

Recent Accounting Pronouncements – In December 2023, Financial Accounting Standards Board issued ASU 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures, which enhances the disclosures required for income taxes in the Company’s annual consolidated financial statements. Notably, this ASU requires entities to disclose specific categories in the effective tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. ASU 2023-09 is effective for the Company in its annual reporting for fiscal 2025 on a prospective basis. Early adoption and retrospective reporting are permitted. The Company is currently evaluating the impact of ASU 2023-09 on its consolidated financial statements.
