1. NATURE OF BUSINESS AND ORGANIZATION

Cellectar Biosciences, Inc. (the "Company") is a late-stage clinical biopharmaceutical company focused on the discovery and development of drugs for the treatment of cancer leveraging our proprietary phospholipid drug conjugate™ (PDC™) delivery platform that are designed to specifically targets cancer cells and deliver improved efficacy and better safety as a result of fewer off-target effects.

The Company has incurred losses since inception in devoting substantially all of its efforts toward research and development and has an accumulated deficit of approximately $133,132,597 at March 31, 2021. During the three months ended March 31, 2021, the Company generated a net loss of approximately $6,357,170 and expects that it will continue to generate operating losses for the foreseeable future. However, the Company believes that its cash balance at March 31, 2021 is adequate to fund our basic budgeted operations for at least 12 months from the filing of these financial statements.The Company’s ability to execute its current operating plan depends on its ability to obtain additional funding via the sale of equity and/or debt securities, a strategic transaction or otherwise. The Company plans to continue to actively pursue financing alternatives , but there can be no assurance that it will obtain the necessary funding.

The accompanying Condensed Consolidated Balance Sheet as of December 31, 2020 has been derived from the Company’s audited financial statements. The accompanying unaudited Condensed Consolidated Balance Sheet as of March 31, 2021, and the Condensed Consolidated Statements of Operations, the Condensed Statements of Stockholders’ Equity and, the Condensed Consolidated Statements of Cash Flows for the three months ended March 31, 2021 and 2020, and the related interim information contained within the notes to the Condensed Consolidated Financial Statements, have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions, rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, they do not include all the information and the notes required by U.S. GAAP for complete financial statements. In the opinion of management, the unaudited interim condensed consolidated financial statements reflect all adjustments which are of a nature necessary for the fair presentation of the Company’s consolidated financial position at March 31, 2021 and consolidated results of its operations, stockholders’ equity and cash flows for the three months ended March 31, 2021 and 2020. The results for the three months ended March 31, 2021 are not necessarily indicative of future results.

These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto included in the Company’s Form 10-K for the fiscal year ended December 31, 2020, which was filed with the SEC on March 2, 2021.

Principles of Consolidation — The consolidated financial statements include the accounts of the Company and the accounts of its wholly-owned subsidiary. All significant intercompany accounts and transactions have been eliminated in consolidation.

Fixed Assets — Property and equipment are stated at cost. Depreciation on property and equipment is provided using the straight-line method over the estimated useful lives of the assets (3 to 10 years). Because of the significant value of leasehold improvements purchased, leasehold improvements are depreciated over 64 months (their estimated useful life), which represents the full term of the lease. Our only long-lived assets are property and equipment. The Company periodically evaluates long-lived assets for potential impairment. Whenever events or circumstances change, an assessment is made as to whether there has been impairment to the value of long-lived assets by determining whether projected undiscounted cash flows generated by the applicable asset exceed its net book value as of the assessment date. There were no long-lived fixed asset impairment charges recorded during the three months ended March 31, 2021 or year ended December 31, 2020.

Right-of-Use (ROU) Asset and Lease Liabilities -On January 1, 2019, the Company adopted FASB Accounting Standards Codification (“ASC”) Topic 842 using the modified retrospective method for all material leases that existed at or commenced after January 1, 2019. ROU Assets are amortized over their estimated useful life, which represents the full term of the lease.

Stock-Based Compensation — The Company uses the Black-Scholes option-pricing model to calculate the grant-date fair value of stock option awards. The resulting compensation expense for awards that are not performance-based is recognized on a straight-line basis over the service period of the award, which for grants issued in 2021 and 2020 ranged from one year to three years for stock options.

Research and Development — Research and development costs are expensed as incurred. To the extent that such costs are reimbursed by the federal government on a fixed price, best efforts basis and the federal government is the sole customer for such research and development, the funding is recognized as a reduction of research and development expenses.

Income Taxes — Income taxes are accounted for using the liability method of accounting. Under this method, deferred tax assets and liabilities are determined based on temporary differences between the financial statement basis and tax basis of assets and liabilities and net operating loss and credit carryforwards using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when it is more likely than not that some portion of the deferred tax assets will not be realized. Management has provided a full valuation allowance against the Company’s gross deferred tax asset. Tax positions taken or expected to be taken in the course of preparing tax returns are required to be evaluated to determine whether the tax positions are “more likely than not” to be sustained by the applicable tax authority. Tax positions deemed not to meet a more-likely-than-not threshold would be recorded as tax expense in the current year. There were no uncertain tax positions that require accrual to or disclosure in the financial statements as of March 31, 2021 and December 31, 2020.

Fair Value of Financial Instruments — The guidance under FASB ASC Topic 825, Financial Instruments, requires disclosure of the fair value of certain financial instruments. Financial instruments in the accompanying financial statements consist of cash equivalents, prepaid expenses and other assets, accounts payable and long-term obligations. The carrying amount of cash equivalents and accounts payable approximate their fair value as a result of their short-term nature. (See Note 2)

Concentration of Credit Risk — Financial instruments that subject the Company to credit risk consist of cash and equivalents on deposit with financial institutions. The Company’s excess cash as of March 31, 2021 and December 31, 2020 is on deposit in interest-bearing transaction accounts with well-established financial institutions. At times, such amounts may exceed the FDIC insurance limits. As of March 31, 2021, and December 31, 2020, uninsured cash balances totaled approximately $53,100,000 and $56,700,000, respectively.

Recently Adopted Accounting Pronouncements - For the fiscal year beginning January 1, 2021, management early adopted Accounting Standards Update ("ASU") 2020-06 using the modified retrospective method. ASU 2020-06 simplifies entities' accounting for convertible instruments by eliminating the cash conversion and beneficial conversion feature ("BCF") models outlined in ASC 470-20 Debt-Debt with Conversion and Other Options. Under ASU 2020-06, convertible instruments that would have previously been subject to the BCF or cash conversion guidance no longer require separate accounting for the conversion feature. Entities may elect to early adopt ASU 2020-06 for fiscal years beginning after December 15, 2020. Since the Company early adopted ASU 2020-06 beginning January 1, 2021, the Company would no longer be required to recognize a BCF even when shareholder approval is received. In December 2020, the Company completed a private placement where we issued Series D convertible preferred stock. The preferred shares are convertible into shares of common stock upon receipt of stockholder approval of the issuance of the underlying shares of common stock as required by Nasdaq Marketplace Rule 5635(d) at a special stockholder meeting. The shareholders approved this conversion on February 25, 2021. As such, management will continue to account for the Series D Preferred Stock in equity without any separate accounting for the conversion options
