Imunon, Inc.

NOTES TO THE CONDENSED CONSOLIDATED

FINANCIAL STATEMENTS

(UNAUDITED)

SEPTEMBER 30, 2025

Note 1. Business Description

Imunon, Inc. (“Imunon” or the “Company”) is a clinical-stage biotechnology company focused on advancing a portfolio of innovative treatments that harness the body’s natural mechanisms with the aim to generate safe, effective and durable responses across a broad array of human diseases, constituting a differentiating approach from conventional therapies. Imunon is developing its non-viral DNA technology across its modalities. The first modality, TheraPlas®, is developed for the coding of proteins and cytokines in the treatment of solid tumors where an immunological approach is deemed promising. The second modality, PlaCCine®, is developed for the coding of viral antigens that can elicit a strong immunological response. This technology may represent a promising platform for the development of vaccines in infectious diseases.

The Company’s lead clinical program, IMNN-001, is a DNA-based immunotherapy for the localized treatment of advanced ovarian cancer that has completed multiple clinical trials including one Phase II clinical trial (OVATION 2) and is currently conducting a Phase 3 clinical trial (OVATION 3). IMNN-001 works by instructing the body to produce safe and durable levels of powerful cancer-fighting molecules, such as interleukin-12 and interferon gamma, at the tumor site. Additionally, the Company has completed dosing in a first-in-human study of its COVID-19 booster vaccine (IMNN-101). The Company will continue to leverage these modalities and to advance, either directly or through partnership, the technological frontier of plasmid DNA to better serve patients with difficult-to-treat conditions.

Note 2. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements, which include the accounts of the Company and its wholly owned subsidiaries, have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. All significant intercompany balances and transactions have been eliminated in consolidation. During the quarter and nine-month period ended September 30, 2025, there were no changes to the Company’s accounting policies. Certain information and disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations.

In the opinion of management, all adjustments, consisting only of normal recurring accruals considered necessary for a fair presentation, have been included in the accompanying unaudited condensed consolidated financial statements. Operating results for the nine months ended September 30, 2025 and 2024 are not necessarily indicative of the results that may be expected for any other interim period(s) or for any full year. For further information, refer to the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, filed with the Securities and Exchange Commission on February 27, 2025.

The preparation of financial statements in conformity with GAAP requires management to make judgments, estimates, and assumptions that affect the amounts reported in the Company’s condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. Events and conditions arising subsequent to the most recent balance sheet date have been evaluated for their possible impact on the unaudited condensed consolidated financial statements and accompanying notes.

Going Concern Uncertainty

Since inception, the Company has incurred substantial operating losses, principally from expenses associated with the Company’s research and development programs, clinical trials conducted in connection with the Company’s drug candidates, and applications and submissions to the U.S. Food and Drug Administration (“FDA”). The Company has not generated significant revenue and has incurred significant net losses in each year since inception. For the nine months ended September 30, 2025, the Company had a net loss of $10.3 million and used $10.2 million to fund operations. As of September 30, 2025, the Company has incurred approximately $419 million of cumulative net losses. As of September 30, 2025, the Company had $5.3 million in cash and cash equivalents to fund its operations.

The Company’s ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility in, financial markets in the U.S. and worldwide resulting from the recent tariff announcement by the U.S. federal government, the Russian invasion of Ukraine and the unrest in the Middle East. The Company continues to monitor its operating activities in light of these events, and it is possible that these events could result in a variety of risks to the business. The specific impact, if any, is not readily determinable as of the date of these unaudited condensed consolidated financial statements.

The Company has based its estimates on assumptions that may prove to be wrong. The Company may need to obtain additional funds sooner or in greater amounts than it currently anticipates. Potential sources of financing include strategic relationships, public or private sales of the Company’s shares or debt and other sources. If the Company raises funds by selling additional shares of common stock or other securities convertible into common stock, the ownership interest of existing stockholders may be diluted.

The actual amount of funds the Company will need to operate is subject to many factors, some of which are beyond the Company’s control. These factors include the progress of research activities; the number and scope of research programs; the progress of preclinical and clinical development activities; the progress of the development efforts of parties with whom the Company has entered into research and development agreements; the costs associated with additional clinical trials of drug candidates; the ability to maintain current research and development licensing arrangements and to establish new research and development and licensing arrangements; the ability to achieve milestones under licensing arrangements; the costs involved in prosecuting and enforcing patent claims and other intellectual property rights; and the costs and timing of regulatory approvals.

A fundamental component of the ability to continue as a going concern is the Company’s ability to raise capital as required, as to which no assurances can be provided. To address the additional funding requirements of the Company, management has undertaken the following initiatives:

The Company’s ability to continue as a going concern will depend on its ability to raise additional capital, attain further operating efficiencies, reduce expenditures, and, ultimately, to generate revenue. There are no assurances that these future funding and operating efforts will be successful. If management is unsuccessful in these efforts, the Company’s current capital is not expected to be sufficient to fund operations for the next twelve months.

Such conditions raise substantial doubts about the Company’s ability to continue as a going concern. Based on the above, management has determined there is substantial doubt regarding our ability to continue as a going concern. The report of our independent registered public accounting firm for the year ended December 31, 2024, includes an explanatory paragraph which expresses substantial doubt about our ability to continue as a going concern.

Management’s plan includes private or public equity financings, collaborations, or other strategic transactions such as raising funds from outside investors via its ATM program and other potential funding sources. The Company may not be able to obtain funding on acceptable terms, or at all. The terms of any financing may adversely affect the holdings or the rights of the Company’s stockholders. The Company’s ability to raise additional funds will depend, among other factors, on financial, economic and market conditions, many of which are outside of its control, and it may be unable to raise financing when needed, or on terms favorable to the Company. If the Company is unable to obtain sufficient capital to fund its operations it may be required to evaluate alternatives. The Company’s condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of assets, carrying amounts or the amount and classification of liabilities that may be required should the Company be unable to continue as a going concern.

**Note 3. New Accounting Pronouncements **

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) and are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued accounting pronouncements will not have a material impact on the Company’s condensed consolidated financial position, results of operations, and cash flows, or do not apply to its operations.

In December 2023, the FASB issued Accounting Standards Update (“ASU”) No. 2023-09, “Improvements to Income Tax Disclosures”, which requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation, and modifies other income tax-related disclosures. ASU No. 2023-09 is effective for the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. Early adoption is permitted. The Company is currently evaluating the impact of the ASU on the income tax disclosures within the unaudited condensed consolidated financial statements; the Company expects changes to the Company’s income tax disclosure.

In November 2024, the FASB issued ASU No. 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures: Disaggregation of Income Statement Expenses” (“ASU 2024-03”). ASU 2024-03 will require more detailed information about the types of expenses in commonly presented income statement captions such as “Cost of sales” and “Selling, general and administrative expenses”. The new guidance is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027 with early adoption permitted. The Company is currently evaluating the impact that this change will have on the Company’s disclosures.

Note 4. Net Loss per Common Share

Basic and diluted net loss per common share was computed by dividing net loss for the year by the weighted average number of shares of common stock outstanding, both basic and diluted, during each period. The impact of common stock equivalents has been excluded from the computation of diluted weighted average common shares outstanding in periods where there is a net loss, as their effect is anti-dilutive.

The total number of shares of common stock issuable upon exercise of warrants, stock option grants and equity awards was 990,233 and 447,499 shares for the nine months ended September 30, 2025 and 2024, respectively. For the nine-month periods ended September 30, 2025 and 2024, diluted loss per common share was the same as basic loss per common share as the other warrants, and equity awards that were convertible into shares of the Company’s common stock were excluded from the calculation of diluted loss per common share as their effect would have been anti-dilutive.

The Company declared a 15% stock dividend that was distributed on August 21, 2025 to stockholders of record as of August 7, 2025. In accordance with Accounting Standards Codification (“ASC”) 260, basic and diluted earnings per share amounts and weighted-average shares outstanding have been restated for all periods presented to reflect the effect of this stock dividend. The Company did not pay any dividends during the first nine months of 2024.

Note 5. Segment Performance Measures and Expenses

The Company operates inone segment for the research and development of product candidates. The Company’s chief operating decision maker (“CODM”) has been identified as the Chief Executive Officer and President, who reviews operating results to make decisions about allocating resources and assessing performance for the entire Company based on condensed consolidated financial information. Consequently, the Company views the entire organization asone reportable segment and the strategic purpose of all operating activities (including general and administrative expenses) is to support that one segment. As a pre-revenue research and development company, the CODM evaluates company-wide performance and allocates resources based on non-financial research and development milestones achieved, and to a lesser extent, financial measures of performance such as clinical development (research and development expenses) and general and administrative expenses incurred. The CODM does not generally evaluate the Company’s performance using asset or historical cash flow information.

The table below provides a summary of the significant expense categories and consolidated net loss details provided to the CODM (in thousands):

Note 6. Other Accrued Liabilities

Other accrued liabilities at September 30, 2025 and December 31, 2024 include the following:

Note 7. Stockholders’ Equity

On May 15, 2024, the Company filed with the U.S. Securities and Exchange Commission (“SEC”) a shelf registration statement on Form S-3 (the “2024 Registration Statement”) for the offer and sale of up to $75 million of its securities. The 2024 Registration Statement was declared effective on May 22, 2024. The 2024 Registration Statement is intended to provide the Company with flexibility to raise capital in the future for general corporate purposes. As noted in the prospectus supplement that the Company filed on July 22, 2025, the aggregate market value of outstanding Common Stock held by non-affiliates was approximately $79,075,969, based on 2,121,895 shares of Common Stock outstanding as of July 22, 2025, of which 2,100,291 shares were held by non-affiliates, and a price of $37.65 per share, which was the last reported sale price of Common Stock on The Nasdaq Stock Market LLC (“Nasdaq”) on June 2, 2025. As a result, the Company’s public float increased above $75.0 million, and the Company is no longer subject to the limitations contained in General Instruction I.B.6 of Form S-3.

Reverse Stock Split

On July 25, 2025, the Company effected a 15-for-1 reverse stock split of its common stock which was made effective for trading purposes as of 12:01 a.m. ET on July 25, 2025. As of that date, each 15 shares of issued and outstanding common stock and equivalents were consolidated into one share of common stock. All shares have been restated to reflect the effects of the 15-for-1 reverse stock split. In addition, at the market open on July 25, 2025, the Company’s common stock started trading under a new CUSIP number 15117N701 although the Company’s ticker symbol, IMNN, remained unchanged.

The reverse stock split was previously approved by the Company’s stockholders at the 2025 Annual Meeting held on July 11, 2025, and the Company subsequently filed a Certificate of Amendment to its Certificate of Incorporation to effect the stock consolidation. The primary reasons for the reverse stock split and the amendment are:

Immediately prior to the reverse stock split, the Company had 31,828,447 shares of common stock outstanding which consolidated into 2,121,942 shares of the Company’s common stock. No fractional shares were issued in connection with the reverse stock split. All fractional shares were rounded up to the nearest whole share. The reverse stock split did not impact the total authorized number of shares of common or preferred stock or the par value thereof. The number of outstanding options, stock awards and warrants were adjusted accordingly, with outstanding options and stock awards being reduced from approximately 1.9 million to approximately 0.1 million and outstanding warrants being reduced from approximately 12.7 million to approximately 0.8 million.

Increase to Authorized Shares

At the 2025 Annual Meeting of Stockholders (the “Annual Meeting”) of the Company held on July 11, 2025, upon the recommendation of the Company’s board of directors, the Company’s stockholders voted on and approved an amendment to the Company’s Restated Certificate of Incorporation to increase the number of authorized shares of common stock from 112,500,000 shares to 350,000,000 shares, and to make a corresponding change to the number of authorized shares of capital stock. Such amendment became effective on July 11, 2025 upon filing with the Secretary of State of the State of Delaware.

Stock Dividend

On July 28, 2025, the Company announced that the Company’s Board of Directors approved a 15% stock dividend,0.15 shares of common stock (the “Stock Dividend”) per share of the Company’s issued and outstanding shares of common stock and per each common stock equivalent with dividend rights.

The Board of Directors fixed August 7, 2025 as the record date (the “Record Date”) for the Stock Dividend, and the Stock Dividend was issued on August 21, 2025 to stockholders of record as of the Record Date.

The number of outstanding warrants were adjusted accordingly, with outstanding warrants increasing from approximately 0.8 million to approximately 1.0 million.

At the Market Offering Agreement

On May 15, 2024, the Company amended the At the Market Offering Agreement, dated as of May 25, 2022 (the “ATM Agreement”) with H.C. Wainwright & Co., LLC (“Wainwright”) as sales agent. Pursuant to the terms of the amended ATM Agreement, the Company may offer and sell, from time to time, through Wainwright, shares of the Company’s common stock having an aggregate offering price of up to $5,500,000. The Company intends to use the net proceeds from any offering under the amended ATM Agreement for general corporate purposes, including research and development activities, capital expenditures and working capital.

On July 30, 2024, the Company notified Wainwright that it was suspending its use of and terminating the “at the market offering” sales agreement prospectus (the “ATM Prospectus”), related to the potential issuance from time to time of the Company’s common stock pursuant to the ATM Agreement, by and between the Company and Wainwright. Notwithstanding the termination of the ATM Prospectus, the ATM Agreement remains in full force and effect.

On September 3, 2024, the Company filed a new prospectus supplement to the 2024 Registration Statement with the SEC for an aggregate offering price of up to $5,500,000 related to the potential issuance from time to time of the Company’s common stock pursuant to the ATM Agreement with Wainwright as sales agent.

On July 22, 2025, the Company filed a prospectus supplement (the “Prospectus Supplement”) to register an additional $4,500,000 of shares of the Company’s common stock, par value $0.01 per share issuable pursuant to the At the Market Offering Agreement, dated as of May 25, 2022, as amended by Amendment No. 1 to At the Market Offering Agreement, dated as of May 15, 2024 (as amended, the “Sales Agreement”), by and between the Company and H.C. Wainwright & Co., LLC, as sales agent or principal (the “Sales Agent”). The Company previously registered the offer and sale of up to $5,500,000 of shares of Common Stock through the Sales Agent under the Sales Agreement. Prior to the date hereof, the Company has sold an aggregate of $1,815,267 shares of Common Stock through the Sales Agent under the Sales Agreement. Accordingly, the Prospectus Supplement covers an aggregate of $8,184,733 of Shares, consisting of $3,684,733 remaining of the amount originally registered and the additional $4,500,000 increase under the Prospectus Supplement.

The Company sold 5,932 shares of common stock under the ATM Agreement for net proceeds of $99,506 during 2024. During 2025, the Company sold 551,265 shares of common stock under the ATM Agreement for net proceeds of $3,638,767 through September 30, 2025.

Pursuant to the terms of the Agreement, the Company will issue to the Warrant Holders an aggregate of 194,734 shares of Common Stock (the “Warrant Exchange Shares”), on a one-for-one basis, in exchange for shares issuable under the Warrants (the “Warrant Exchange”), in reliance on an exemption from registration provided by Section 3(a)(9) of the Securities Act of 1933, as amended (the “Securities Act”). Pursuant to the Agreement, the Warrant Holders also agreed to waive the Company’s compliance with the provisions of Section 4.12(b) of the Securities Purchase Agreement, dated July 30, 2024, with respect to any Company Variable Rate Transaction (as defined in the Purchase Agreement) for a period of forty-five (45) days from the date of the Agreement and agreed to a lock up period on the Warrant Exchange Shares ending on the opening of trading on May 14, 2025.

The Prefunded Warrants became exercisable immediately after issuance for a term of two and one-half years following the date of issuance. The Warrants will be exercisable upon receipt of such approval as may be required by the applicable rules and regulations of the Nasdaq Stock Market (or any successor entity) from the stockholders of the Company with respect to issuance of all of the Warrants and the shares of Common Stock upon the exercise thereof (“Stockholder Approval,” and such date, the “Stockholder Approval Date”) and have a term of three years. The prefunded warrants were exercised in full on June 16, 2025 and June 18, 2025.

In addition, the Company issued to H.C. Wainwright & Co., LLC warrants (the “Placement Agent Warrants”) to purchase up to an aggregate of 24,075 shares of common stock at an exercise price equal to $8.44 per share.

On July 11, 2025, the Company’s stockholders approved the issuance of the Warrants.

Note 8. Stock-Based Compensation

The Company has long-term compensation plans that permit the granting of equity-based awards in the form of stock options, restricted stock, restricted stock units, stock appreciation rights, other stock awards, and performance awards.

In 2018, stockholders approved the Imunon, Inc. 2018 Stock Incentive Plan (the “2018 Plan”). The 2018 Plan, as amended, permits the granting of 131,334 shares of Imunon common stock as equity awards in the form of incentive stock options, nonqualified stock options, restricted stock, restricted stock units, stock appreciation rights, other stock awards, performance awards, or in any combination of the foregoing.

As of September 30, 2025, there were a total of 264,667 shares of Imunon common stock reserved for issuance under the 2018 Plan, which were comprised of 24,986 shares of Imunon common stock subject to equity awards previously granted under the 2018 Plan and 235,509 shares of Imunon common stock available for future issuance under the 2018 Plan. At the 2025 Annual Stockholders Meeting of the Company held on July 11, 2025, stockholders approved an amendment to the 2018 Plan, as previously amended, whereby the Company increased the number of shares of common stock available by 133,333 to a total of 264,667 under the 2018 Plan, as amended.

Total compensation cost related to stock options and restricted stock awards was approximately $0.1 million and $0.4 million of expense for the nine months ended September 30, 2025 and 2024, respectively. Of these amounts, approximately $29,000 for the nine months ended September 30, 2025 and $0.2 million expense for the same period ended September 30, 2024 were charged to research and development expenses and $0.1 million of expense for the nine months ended September 30, 2025 and $0.2 million of expense for the nine months ended September 30, 2024 were charged to general and administrative expenses.

A summary of stock option awards and restricted stock grants, inclusive of awards granted under the 2018 Stock Plan and Inducement Option Grants for the nine months ended September 30, 2025 is presented below:

As of September 30, 2025, there was $58,000 of total unrecognized compensation cost related to non-vested stock-based compensation arrangements. That cost is expected to be recognized over a period of three tofour years. The weighted average grant date fair value of the stock options granted was $11.44 during the nine months ended September 30, 2025.

The fair values of stock options granted were estimated at the date of grant using the Black-Scholes option pricing model. The Black-Scholes model was originally developed for use in estimating the fair value of traded options, which have different characteristics from the Company’s stock options. The model is also sensitive to changes in assumptions, which can materially affect the fair value estimate. The Company used the following assumptions for determining the fair value of options granted under the Black-Scholes option pricing model:

Expected volatilities utilized in the model are based on historical volatility of the Company’s stock price. The risk-free interest rate is derived from values assigned to U.S. Treasury bonds with terms that approximate the expected option lives in effect at the time of grant.
