**EXPLANATORY NOTE**

This Amendment No. 1 to Form 10-K (this "Amendment") amends the [Annual Report on Form 10-K for the fiscal year ended December 31, 2025](https://www.sec.gov/ix?doc=/Archives/edgar/data/1279704/000110465926023167/clrb-20251231x10k.htm), originally filed with the Securities and Exchange Commission on March 4, 2026 (the "Original 10-K") by Cellectar Biosciences, Inc. (the "Company", "Cellectar", "we", "us", "our"). We are filing this Amendment to provide the additional information required by Part III (Items 10, 12, 13 and 14) of Form 10-K. Portions of this information was previously omitted from the Original 10-K in reliance on General Instruction G(3) to Form 10-K, which permits the information in the above-referenced items to be incorporated in the Original 10-K by reference to our definitive proxy statement if such statement is filed no later than 120 days after our fiscal year-end. We are filing this Amendment to include such information in the Original 10-K because our definitive proxy statement will be filed later this year. Specifically, this Amendment addresses the following changes:

● Items 10, 12, 13 and 14 of Part III of the Original 10-K are hereby deleted in their entirety and replaced with the following Items 10, 12, 13 and 14 of Part III set forth below.

● As required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended, currently dated certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002 are attached hereto as Exhibit 31.2 and Exhibit 31.4, respectively. Therefore, Item 15 of Part IV of the Original 10-K is being amended to add such new certificates as filed exhibits hereto. Since no financial statements are included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted.

● The cover page has been amended to update the number of ordinary shares outstanding and to remove the statement that information is being incorporated by reference from our definitive proxy statement.

Except as described above, no other changes have been made to the Original 10-K. Accordingly, this Amendment should be read in conjunction with the Original 10-K. The Original 10-K continues to speak as of the date of the Original 10-K, and we have not updated the disclosures contained therein to reflect any events which occurred at a date subsequent to the filing of the Original 10-K.

The audit fees for the fiscal year ended December 31, 2024, are inclusive of fees related to the restatement of the Company's annual financial statements for the fiscal years ended December 31, 2023, and December 31, 2022.

Our Audit Committee has determined that the services Deloitte performed for us during fiscal 2025 and fiscal 2024 were at all times compatible with its independence.

**Policy on Pre-Approval of Audit and Non-Audit Services**

Our Audit Committee approves each engagement for audit and non-audit services before we engage our independent auditor to provide those services.

Our Audit Committee has not established any pre-approval policies or procedures that would allow our management to engage our independent auditor to provide any specified services with only an obligation to notify the Audit Committee of the engagement for those services. None of the services provided by Deloitte for the fiscal years ended December 31, 2025 and December 31, 2024 were obtained in reliance on the waiver of the pre-approval requirement afforded in SEC regulations.
