Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation and Summary of Significant Accounting Policies | 1. Basis of Presentation and Summary of Significant Accounting Policies Perspective Therapeutics, Inc. is a radiopharmaceutical development company that is pioneering advanced treatment applications for cancers throughout the body. The accompanying condensed consolidated financial statements are those of Perspective Therapeutics, Inc., and its wholly owned subsidiaries, referred to herein as “Perspective Therapeutics” or the “Company.” All significant intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, all adjustments necessary for the fair presentation of the condensed consolidated financial statements for the interim periods presented have been included. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and related notes as set forth in the Company’s Annual Report on Form 10-K for the period ended December 31, 2025 filed with the Securities and Exchange Commission (SEC) on March 16, 2026 (2025 Form 10-K). The unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP). Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures are adequate for the information not to be misleading. The unaudited condensed consolidated financial statements reflect, in management’s opinion, all adjustments of a normal, recurring nature that are necessary for the fair statement of the Company’s financial position, results of operations and cash flows for the interim periods, but are not necessarily indicative of the results expected for the full fiscal year or any other period. Segment Information A segment is defined as a component of an entity that has discrete financial information available for regular evaluation by the Chief Operating Decision Maker (CODM) and is used to make decisions on how to allocate resources and assess performance. The Company has one operating and reportable segment, which is its radiopharmaceutical development segment. The accounting policies of the radiopharmaceutical development segment are the same as those reported in Note 2, Summary of Significant Accounting Policies, in the 2025 Form 10-K. The measurement of segment profit or loss is reported as “net loss” in the Condensed Consolidated Statements of Operations and Comprehensive Loss. The Company monitors its cash, cash equivalents and short-term investments, as reported in the Condensed Consolidated Balance Sheets, to determine funding for its research and development. To allocate resources, the Company’s CODM, who is its Chief Executive Officer, regularly reviews scientific data from clinical and preclinical studies and forecasted expenses for continuing operations. The Company currently does not generate revenue from commercial products and incurs the majority of its operating expenses in the United States. Liquidity The Company assesses its liquidity in terms of its ability to generate cash to fund its operating, investing and financing activities. The Company has had a history of operating losses and an absence of significant recurring cash inflows from revenue. At March 31, 2026, the Company had cash, cash equivalents and short-term investments of $270.9 million and total accumulated deficit of $361.0 million. The Company has historically financed its operations primarily through selling equity. The Company believes that its $270.9 million of cash, cash equivalents and short-term investments as of March 31, 2026 will enable it to fund its current planned operations into late 2027, t hough it may raise additional capital through a combination of equity offerings, debt financings, collaborations, strategic alliances and marketing, distribution or licensing arrangements and/or government funding and grants. In February 2026, the Company announced the closing of an underwritten offering with gross proceeds of approximately $175.0 million. The accompanying unaudited condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The operating plan may change as a result of many factors currently unknown to management, and there can be no assurance that the current operating plan will be achieved in the timeframe anticipated by management or at all, and the Company may need to seek additional funds sooner than anticipated. The unaudited condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from potential unknown factors. Summary of Significant Accounting Policies The Company’s significant accounting policies and recent accounting pronouncements are described in Note 2, Summary of Significant Accounting Policies, to the consolidated financial statements in Item 8 of the 2025 Form 10-K. There have been no material changes to the Company’s significant accounting policies.
